Johann Georg Teede, a German naturalist who collected in Portugal and Surinam before 1799 and is mentioned in the Journal für die Botanik dated 1799. There was another Teede who collected in Africa in 1896 but that was someone else. The genus Teedia in the Scrophulariaceae was published in 1799 by German naturalist Karl Asmund Rudolphi.

Robert Templeman, seedsman in the Cape Town Botanical Garden, commemorated with Pillansia templemannii (formerlyTritonia templemannii) and the former taxon Gladiolus templemannii, now synonymized to G. virescens. (Gunn & Codd; JSTOR)
The taxon Abutilon theophrasti, which is often considered a weed and has the common name velvetleaf or indian mallow, has a long history going back to about 900 B.C. 'Abutilon' was first used by the Persian philosopher and polymath Avicenna or Abū Alī al-usayn ibn Abd Allāh ibn Sīnā (Ibn-Sina) for plants that resembled mallows or mulberries. For some unknown reason, Theophrastus of Eresus (c.371-288 BC), an early Greek botanist and student of Aristotle's who wrote nine books on the history of plants, used the Greek word 'side' which was a name that applied to water plants for plants that today are called sidas or velvetleafs. This is the root of the generic names Sida, Sidalcea and several others. It seems that there was a plant that Theophrastus called althaia or marsh mallow, and the specific epithet theophrasti as applied to a taxon of genera Abutilon was carried over from previously used names such as Althaea theophrasti, and was meant to indicate that this was the species referred to by Theophrastus. Linnaeus had classified the velvetleaf as Sida abutilon in 1753 and then Phillip Miller, who was chief gardener at the Chelsea Physic Garden for fifty years, published the name Abutilon in the fourth edition of his Gardener's Dictionary in 1754. In 1787 the German botanist Friedrich Kasimir Medikus rearranged the Malvaceae and placed Sida abutilon in the genus Abutilon, giving it the name of Abutilon theophrasti. Subsequent to that, the German botanist Joseph Gaertner (1732-1791) reclassified the plant as Abutilon avicennae, to honor the Persian Avicenna, but the rules of nomenclature dictated that the epithet of Medikus took precedence, and that's the way it has remained. The name Abutilon is often stated to be of Arabic or Arabian origin, but since Avicenna was Persian, this is not correct. There are at least ten other species with this specific epithet but none of them appear in southern Africa. (Weed Science Society of America; Encyclopedia of Evolution)
Dr George Thom (1789-1842), a Scottish minister and missionary of the N.G. Kerk who sent botanical and geological specimens overseas to Profs. W. J Hooker and Couper in Glasgow. He is commemorated withMystropetalon thomii, Otholobium thomii, the former taxon Tripteris thomii (now T. oppositifolia) and possibly also for Selago thomii. (Hugh Clarke, pers. comm.; Gunn & Codd)

Louis-Marie Aubert du Petit-Thouars (1758-1831), a well-known French botanist who during the French Revolution was imprisoned for two years and then exiled to Madagascar and the nearby islands of L'île de France (Mauritius) and L'île de Bourbon (La Réunion) where he became involved in botany and started collecting plants. He was particularly interested in orchids and published the names of eleven orchid genera and many species. His years there were documented in the books Histoire des végétaux recueillis dans les îles de France, de Bourbon et de Madagascar,Mélanges de botanique et de voyages, and Histoire particulière des plantes orchidées recueillies dans les trois îles australes de France, de Bourbon et de Madagascar. After ten years he returned to France with a collection of some 2000 plants most of which went to the Muséum de Paris. He was later elected to the Academy of Sciences. He is commemorated with Pentamaris thuarii, Digitaria thouarsiana, Voacanga thouarsii, Torenia thouarsii, and the former taxa Tetraria thuarii (now T. compar), Pseudocyphellaria thouarsii (now P. intricata) and Corymborkis thouarsii (now C. corymbis). He is also commemorated with the genera Thouarsiora and Thouarsia, which do not appear in southern Africa. His younger brother, Aristide Aubert Du Petit Thouars, was a naval officer and a hero of the Battle of the Nile. (JSTOR; Wikipedia; CRC World Dictionary of Plant Names)
Mats Thulin (1948- ), Swedish botanist, professor at Uppsala University who has devoted more than twenty years in his study of the family Campanulaceae in Africa, and author of The Genus Wahlenbergia, Leguminosae of Ethiopia, co-author of Introduction to Phylogeny and Systematics of Flowering Plants, and editor of the 4-volume Flora of Somalia, commemorated with Wahlenbergia thulinii.

Carl Peter Thunberg (1743-1828), Swedish botanist and physician who travelled as surgeon with ships of the Dutch East India Company and did extensive botanical exploration in southern Africa and Japan. He was a student of Linnaeus, one of his so-called apostles and perhaps his foremost disciple, a plant collector and explorer, and after his travelling years was a professor of botany and medicine at Uppsala. He was commissioned by Johannes Burmann to visit Dutch colonies and Japan in order to obtain plants for Dutch botanical gardens, spent three years in the Cape Colony learning Dutch and collecting plants in the company of such men as Scottish botanist Francis Masson and Scottish soldier and naturalist Robert Jacob Gordon, during which time he collected over 3000 species, 1000 of which were not previously known. He collected mostly pressed specimens, but also seeds, bulbs and live plants, and samples of fauna. He spent two months at Batavia before arriving in Japan, where he spent somewhat more than a year. On his journey home he spent several months in Sri Lanka and then stopped at London to meet Joseph Banks. Upon arriving back in Sweden he learned of the death of Linnaeus. He was elected a member of the Royal Swedish Academy of Sciences, and was the author of Flora Japonica (1784), Prodromus plantarum capensium (1800), Icones plantarum japonicarum (1805), and Flora capensis (1813). His post-travel years were mainly occupied by teaching and scientific work, and he published 293 medical and natural history dissertations during that time. He was also responsible for a new botanical garden at Uppsala Castle and a new institution building housing a botanical museum and a conservatory. The South African botanist Verduyn den Boer memorialized him this way: " long as in our paradise of flowers there wanders a single botanist, so long will the name of Thunberg be held in honored remembrance." He was less known as a prominent entomologist but published papers and described numerous scarab taxa. The genus Thunbergia in the Acanthaceae was published in 1780 by Swedish chemist, botanist and entomologist Anders Jahan Retzius, and the genus Thunbergiella in the Apiaceae was published in 1922 by German mycologist and botanist Karl Friedrich August Hermann Wolff. There are too many taxa with his name on them to list fully but they include Crassula, Silene, Phylica, Wahlenbergia, Scirpus, Jamesbrittenia, Pennisetum, Babiana, Stachys, Gasteria, Cyperus, Euryops, Senecio, Cotula, Muraltia, and many others both current and former. He is also commemorated with the genus Thunbergianthus which does not appear in southern Africa.

Heinrich Julius Tode (1733-1797), German clergyman, educator, botanist and cryptogamist, architect, draftsman and author. The website describes him as a "parson in Pritzier; later cathedral and court preacher and superintendant at Schwerin; known for botanic studies and as poet of hymn and cantata texts." Another website says he was interested mainly in "small, strange-looking things." He was the author of Fungi Mecklenburgenses selecti (Selected Fungi from Mecklenburg). The genus Todea in the Osmundaceae was published in 1801 by German doctor and botanist Johann Jacob Bernhardi based on a previous description by German botanist and pharmacist Carl Ludwig von Willdenow. Just as an amusing aside, the Wikipedia translation of his name to English is Heinrich Julius Death. (CRC World Dictionary of Plant Names;
Alexander Johann August Treichel (1837-1901), German botanist. The genus Treichelia in the Campanulaceae was published in 1874 by German botanist Johann (Georg) Karl Wilhelm Vatke. (CRC World Dictionary of Plant Names)
Triton, in Greek and Roman mythology, the name of a sea-deity, son of Poseidon and Ampritrite, or of Neptune and Salacia, or otherwise of Nereus; also one of a race of inferior deities, or imaginary sea‑monsters, of semi-human form. Triton figures in paiting, sculpture etc.; In heraldry Triton is represented by a bearded man with the hind quarters of a fish, holding a trident and a shell-trumpet. Triton was represented with a horn made of shell, which he blew at the bidding of Neptune to raise or appease the waves. Triton, in Greek mythology the son of Poseidon and Amphitrite and messenger of the sea, usually portrayed with the upper body of a human and the lower body of a fish. The genus Tritonia in the Iridaceae was published in 1802 by British botanist John Bellenden Ker Gawler.

Ryk Tulbagh (1699-1771), Governor of the Cape Colony from 1751 to 1771, with whom Linnaeus corresponded. He joined the Dutch East India Company at the age of 16 and a year later sailed on the vessel Terhorst bound for South Afirca. The town of Tulbagh in the Western Cape was named after him. The genus Tulbaghia in the Alliaceae was published by Swedish botanist Carl Linnaeus in 1771. Tulbagh also sent butterflies to Linnaeus.

William Tyson (1851-1920), Jamaican-born South African botanist, plant collector, teacher and Fellow of the Linnean Society. He started studying medicine but had to give it up because of crippling arthritis in his hands. He worked for the Agricultural Department as librarian and sub-editor of the Agricultural Journal. He made a collection of marine algae which was donated to the Bolus Herbarium. The genus Tysonia in the Boraginaceae was published in 1896 by German-Australian botanist, physician and geographer Ferdinand Jacob Heinrich von Mueller, and William Tyson is also commemorated with many current species names in genera Scabiosa, Disa, Neobolusia, Habenaria,Disperis, Euryops, Helichrysum, Berkheya, Senecio, Lactuca, Xysmalobium, Argyrolobium, Jamesbrittenia, Stachys,Hesperantha, Dierama, Salvia, Cyphia, Dioscorea, Oxalis, Pelargonium, Kniphofia and many others that have been synonymized.
