HEXANDRIA. TRIGYNIA. fiS5 



Species. l.X. asphodeloides. Hab. In New Jersey, and 

 also very abundant on the summit of the Catawba ridge. 

 North Carolina. The dilaiion of tlie filaments towards the 

 base, the disposition of the stjles, or rather stig-mas, and 

 the opening- of the capsule by 3 external sutures in the 

 centre of each cell, in place of the internal margins of the 

 cells or capsules, are characters of much more importance 

 than those which separate tlelonias and Veratrum. 2. tenax. 

 Pursh, 1. p. 243 — In the Northern Andes or Rocky Moun- 

 tains. 3. gramineum, {Helonias graminea, Bot. Mag. 1559.) 



A North American genus, somewhat allied to Jinphode- 

 his? 



348. TOFIELDIA. Hudson, 



Calix triful. Petals 6. Capsules 5, superior, 

 united at the base, many seeded. Seeds naked, 

 (angularly grooved?) Stifles vertical, very short. 



Hoots aggregate, partly horizontal; leaves irideous; 

 spike short and dense; pedicells solitary, minutely bruc- 

 teate at the base. 



Species. 1. T. * glabra, leaves equitant,iiideous; scape 

 terete, smooth; spike short, dense, and oblong, bracies 

 acute, very small; peduncles solitary, angular, about the 

 length of the flowers; petals oblong-ovate, subacute; styles 

 none; capsules distinct, membranaceous, equal in length 

 with tlie corolla. — Hab. In swamps near Wilmington, N. 

 Carolina. Obs. Much more robust than T. pidustris, and 

 the scape not so far exceeding the leaves. Hoots fascicu- 

 lated horizontal; leaves lineur, ensiform; scape 8 or 10 

 incbes high, solid, rather thick than slender, nearly naked, 

 or with a single leaf; spike 10 to 15 lines long; flowers 

 crowded, nunaerous, (30 or more); bractes extremely mi- 

 nute; raciiis exca%ated opposite the pedicells. Calicle o- 

 toothed. i'etfiis greenish white, like those oi' Helonias in 

 their form and disposition. Filamentsof the stamina equal 

 with the petals and germ, subulate, flat, and cons derubly 

 dilated; anthers oblong, cleft at the base. Siyles none; 

 stigmas flat and circular, sessile. Capsules 3, distinct to 

 the base, whitish, membranaceous, soniewiiat gibbously 

 cynibiform, internal margins closed tind bordered, points 

 entire; 6 to 8 seeded. Seeds linear-oblong, a little curved, 

 small and brownish-yellow^, marked with 5 or 6 longitu- 

 dinal and angular ridges.
