with minute points. Flotuers white, as large as in T. an- 

 guhia, but with a fimple, much (hortcr fringe. Fruit four 

 or five inches long, and an inch and a half in diameter, 

 contrafted at the bafe ; its rind thin, fmooth, greenifh, va- 

 riegated ; the pulp white and very bitter, with brown 

 feeds.

 Cochinch. 589. Willd. n. 8. — " Fruit ovate, acute. Leaves 

 lieart-fhaped, three -pointed, many-ribbed, fmooth. — Native 

 of Cochinchina. Stem fhrnbby, climbing, with three-eleft 

 tendrils. Leaves finely toothed, with thick, nearly orbicular, 

 crenMe Jiipulas. Floiuers fringed, white, in axillary fpik.es, 

 with large toothed braBeas. Fruit fmall, yellow, of two 

 cells, with Ivio feeds. Loureiro- 



9. T. pilofa. Villous Hair-blolTom. Loureir. Cochinch. 

 5^8. AVilld. n. 9. — Fruit ovate, acute. Leaves heart- 

 fhaped, toothed, hairy ; the lower ones palmate ; upper 

 three-lobed. Found wild in Cochinchina. Stem rather 

 Ihrubby, chmbing to a .great extent, by means of divided 

 tendrils, hairy as well as the leaves. Spikes lateral, long, 

 witii lanceolate ferrated bradeas. Flowers white, with a 

 long fringe. Fruit fcarlet, of one cell. Seeds rhomboid, 

 comprefTed, lobed, brown. 



10. T. tuberofa- Tuberous Hair-bloflbm. Willd. n. 10. 

 Ait. n. 3. (T. corniculata ; Lamarck Dift. v. I. 191. 

 Anguria fruftu parvo, florum fegmentis ramofis ; Plum. Ic. 

 14. t. 24.) — Fruit elliptic-oblong. Leaves in three deep 

 lobes ; the lateral ones cloven ; all entire. — Native of the 

 Well Indies. M. Thouin fent it in 18 10 to Kew, where 

 it bloffoms in the ftove about June and July. The root is 

 a huge, globular, perennial, tuberculated, flefhy mafs, near 

 a foot in diameter. Stems annual, climbing by fimple ten- 

 drils. Segments of the leaves lanceolate, divaricated, two 

 or three inches long. Flowers fomewhat umbellate. Co- 

 rolla with a longidi rather fparing fringe at the end of each 

 fegment, if we may rely on Burman's copy of Plumier's 

 figure. Willdenow has taken rather an unwarrantable 

 liberty in changing Lamarck's printed names, of this and 

 our fifth fpecies ; though in the prcfent inftance certainly 

 for the better, the refemblance of horns, in the flower, being 

 probably a deception. 



11. T.laciniofa. Jagged Hair-bloflbm. Willd. n. 11. — 

 " Fruit ovate, acute. Leaves heart-fliaped, palmate, with 

 five or fevcn lobes, toothed, fmooth." — Native of the Eafl 

 Indies. Sent by Klein to Willdenow, who defcribes it 

 with a fmooth, (lender, angular, climbing ^em. Leaves 

 two or three inches long, remotely toothed. Male Jlaiuers 

 about fix together, in axillary corymbofe clufters ; with 

 ovate toothed petals : female ones folitar)', on axillary ftalks ; 

 l\\^T pitals fringed.

Obf. It is neceflary to note, that the above charafters, 

 as far as refpefts the ftamens, agree with the fpecific defi- 

 nition of one of the two Linnaean fpecies only. Linnaeus 

 has left a manufcript remark, that " Adanfon refers this 

 genus to Teucricm ;" fee that article. He certainly does 

 fo, in his Families des Plantes, v. 2. 188, like Dillcnius ; but 

 in contradiftion to his own juft charafter of the latter, con- 

 fitting in the want of an upper lip. 



1 . T. dichotomum. Marjoram-leaved Annual Trichofl;ema. 

 Linn. Sp. PI. 834. Willd. n. i. Ait. n. i. Purfli n. i. 

 (Trichoftema; Linn. Hort. Cliffy. 493. T. ftaminibus 

 longiflimis exfertis ; Gron. Virg. ed. 2. 90.) — Stamens 

 very long, prominent. Leaves rhomboid-lanceolate. Flower- 

 ing branches twice forked. — In fields and on funny hills, 

 from Pennfylvania to Carolina. Annual, flowering in July 

 and Auguft. Floiuers large, fine blue. The whole plant 

 has an agreeable refinous fcent. Purjlo, Root fibrous. 

 Stem a fpan higli, ereft, round, downy, with oppofite 

 crofiing branches. Leaves oppofite, lanceolate, obtufe, en- 

 tire, rough, the lower ones accompanied by axillary tufts 

 of fmall leaves, or rudiments of branches. Flowering 

 branches from the bofoms of the upper leaves, taller than 

 the fl.em, crofling each other, and bearing a leaf fimilar to 

 thofe juft defcribed. Each branch ends in a panicled form, 

 with forked divifions, the properfloiver^alis fingle-flowered. 

 Stamens fetaceous, vei-y long. Calyx reflexed after flower- 

 ing. Linn. Hort. Cliff. 



Purfli adopts from Walter, Fl. Carol. 164, a variety 

 with linear leaves, called by that writer T. lineare. 



2. T. brachiatum. Seflile-leaved Trichoftema. Linn. 

 Sp. PI. 834. Willd. n. 2. Ait. n. 2. Purfli n. 2. 

 (Teucrium virginicum, origani folio; Dill. Elth. 380. 

 t. 285.) — Stamens ftiort, within the flower. Leaves ovato- 

 lanceolate. Flowering branches oppofite, panicled. — Native 

 of Virginia, according to Dillejiius. Mr. Purfli never faw 

 this fpecies but in the Bankfian herbarium, nor have we 

 examined an authentie fpecimen. The habit of the plant 

 feems much like the laft, but the leaves are more feflile. 

 Dillenius's reprcfentation of the parts of the fioiuer, though, 

 doubtlefs, accurate, but ill agrees with the Linnxan generic 

 defcription, nor are thofe parts far unlike thofe of a 

 Teucrium. The Jlamens are ftrongly incurved, or involute, 

 and therefore do not projeft out of the flower. We fuf- 

 peft this may not be a diftinft fpecies from the foregoing. 

 Both require elucidation from American botanifts. 



3. T.fpirale. Spiral Trichoftema. Loureir. Cochinch. 

 371. {Cay rdu meo of the Cochinchinefe. ) — " Stamens 

 very long and fpiral. Leaves ovate, acute." — Native of 

 Cochinchina. Stem herbaceous, ereft, fquare, four feet 

 high, with oppofite crofling branches. Leaves oppofite, 

 entire, downy. Flowers pale violet, in long terminal fpikes. 

 Corolla ringent, its upper lip falcate. Stamens very long, 

 rolled up fpirally, and retained within the corolla. Loureiro. 

 This laft charafter anfwers exaftly to Dillenius's plate of 

 T. brachiatum, to which Loureiro thought his plant nearly 

 akin. Not having, probably, accefs to that plate, he did 

 not difcove,r how well it agreed, even where he thought 

 the difference greateft.
