dal. Seeds numerous, anatropous, with a membranaceous arillus 

 on one side ; the testa crustaccous and reticulated. Embryo in the 

 axis of fleshy albumen, slightly curved : cotyledons somewhat 

 plano-convex. — Herbaceous or sometimes sufTrutescent plants (con- 

 fined, except one species, to tropical America) ; the pubescence 

 often hispid, but not stinging. Leaves simple, alternate, exstipulate, 

 sometimes with 2 glands at the apex of the petiole. Peduncles 

 l-flowered : petals mostly yellow. 



1. TURNERA. Plumier, gen. p. \b, t.\2; Linn.; Ga^rtn.fr. t. 78. 



Calyx infundibuliform or obconic at the base. Petals longer than the 

 calyx. Styles 3, simple : stigmas flabcllate, many-cleft. Capsule 3-valved 

 from the apex to the middle.— Herbs or sufTrutescent plants, with the habit 

 of Cistus. 



1. T. cistoidcs (Linn.) : hirsute ^\'^th bristly hairs ; flowers in tlio axils of 

 the upper leaves, and racemose at the summit of the stem ; pedicel free, 

 articulated above the middle, but not bractcolate ; leaves lanceolate, the 

 lower ones oblong, slightly petioled, crenate or obtusely serrate, tomentose 

 beneath, not glandular at the base. — Plumier, Amer. ed. Burm. t. 150, /. 1 ; 

 Pursh, fl. I. p. 206 ; Ell. sTc. 1. p. 370. 



Fields and barren soil, Georgia ! to Florida ! .Tune-Scpt. — We have 

 some doubt as to the identity of our plant with that of the West Indies, which 

 we have not the means of removing by a comparison of specimens. Ours 

 is apparently a perennial plant, more or less hirsute with rigid fulvous hairs, 

 and besides the lower surface of the leaves is tomentose with a stellate pubes- 

 cence ; the upper irdnutely pubescent in the same manner. The lower 

 leaves are oblong and obtuse, the upper mostly lanceolate, and when the 

 raceme is elongated, the upper floral leaves are usually bract-like and much 

 shorter than the pedicels. The flowers are about an inch in diameter when 

 expanded : the seeds rather large, pale, and slightly curved. 



Order LIX. PASSIFLORACE^. Jiiss. 



Sepals 4-5, more or less united below into a tube of variable 

 length, the throat of which is usually lined with a ring of filament- 

 ous processes. Petals 4-5, arising from tlie throat of the calyx on 

 the outside of the filamentous crown, sometimes irregular or want- 

 ing, imbricated in sestivation. Stamens 4-5 (very rarely indefinite), 

 monadelphous, surrounding the stalk of the ovary : anthers introrse, 

 but versatile, and at length turned outwards. Ovary free, stipitate, 

 l.celled, with 3-4 parietal placenta3 : styles 3-4, clavate : stigmas 

 dilated. Fruit naked or surrounded with the persistent calyx, 

 sometimes opening by loculicidal dehiscence, often fleshy and inde- 

 hiscent. Seeds numerous, anatropous, with a brittle sculptured testa,
