24-8 OCTANDRIA. MONOGYNIA. 



long, only 2 or 3 lines wide; flowers produced towards 

 the summits of the brawches, yellow, capsules racesnose 

 octang-ular; margins alated, dorsal angles obtuse, corru- 

 gate; dissepiments very thin and membranaceous, stipe a 

 little shorter than the fruit; racemes 4 to 6 inches long. 



17. hybrida. 18. linearis. Obs. Root lit^neoii^ stem 

 slender/flexuose, rarelyexceeding a span, often branched, 

 the whole plant conspicuously pubescent; leaves linear, 

 somewhat oblong; r;iclical lea^Ks spathulate-oval; flowers 

 briglit yellow nearly the size of those of ffi. fruticosa, for 

 a dwarf variety of wiiich it might almost be mistaken; tube 

 of the calix much longer than the germ; capsules subco- 

 rymbose or terminal, very few, loundish-obovate, with 8 

 grooNCs, usually shorter than the stipe. Hab. From Vir- 

 ginia to Georgia, in open low and sandy vx'oods. 19. c/ny- 

 sant/ia. 20. pusHla. probably a variety of CC. linearis, the 

 capsules of which are sometimes nearly sessile, and the 

 fruit of this isdescril)ed as clavate. 



'2\. * alata. (E.macocnrpa.Pn. Obs. Root perennial, 

 ' perpendicular, caudex dividing into several simple and 

 decumbent stems, 6 to 12 inches long. Leaves linear-lance- 

 olate acute, upon long petioles, in an early state minutely 

 villous and hoary, margin sometimes distantly and glandu- 

 larly denticulate, always pubescent as well as the nerves, 

 opaque betwixt the light, 5 or 6 inches long and about 

 half an inch wide. Flowers sessile, produced below 

 the summit of the stem, axillary; tube of the calix .S 

 or 4 inches long, (and by cultivation, at the expense of the 

 germ, 6 or 7 inches') segments of the calix sublanceolate, 

 acuminate, flat, externally spotted with purple, and co- 

 vered with a short silky vihus; petals very large, obcor- 

 dately dilated, nearly entire. Pollen triangular, connecting 

 at its angles by a fine web of arachnoid filaments. Stigma 

 4-lobed. Capsule oval, of extraordinary magnitude, com- 

 pressed, coriaceous and shining, producing 4 very broad 

 alated margins, but without any intermediate dorsal 

 ridges, as is usual in this section of the genus, there is 

 consequently no dissepiments, the separation of the 4 cells 

 being produced by the dorsal depression. Seeds gibbous 

 and corrugate, with a lacunose margined depression, dis- 

 posed in 2 rows in each cell; length of the capsule about 

 2 inches, breadth one and a half! This splendid and sin- 

 gular species appears to indicate the existence of some 

 distinct and proximate genus. Hab. On the elevated sum- 

 mits of the calcareous and petrosiliceous hills in the vici- 

 nity of the lead-mines of the river Meremeck, SO miles 

 from St. Louis, Louisiana. Discovered by M^. J. Brad-
