so ON THE GENUS ERIOGONUM. 



imperfectly developed axillar^^) pentangular, with a four 

 or five toothed border, producing intermingled with the 

 pedicells plumose filaments a little longer than the involu- 

 crum, most conspicuous in fruiting specimens. Calyx 

 subcyathiform, 6-parted, persistent, unequal, pubescent 

 around the exterior nerve, acute, and tubular at the base ; 

 3 of the interior laminas longer than the exterior^ erect 

 and connivent, enlarging after infloresence, then cordate, 

 oval, and enveloping the seed; the three exterior segments 

 shorter, in fruit reflected, cuneate-oval, obtuse, and con- 

 cave. Stamina 9, disposed by 3's, on the base of the larger 

 divisions of the calyx. Filaments a little longer than the 

 calyx, pubescent towards the base. Anthers short, ob- 

 long, oval, two celled. Germ conoid-ovate, acute. Styles 

 3, filiform, simple, a little longer than the stamens, pubes- 

 cent towards the germ. Stigmata minute, obtuse. Seed 

 conic, acuminate, acutely triangular, smooth, shining, and 

 of a testaceous colour; in a marcescent state, at the period 

 of germination, partly opening at the base like a trivalvular 

 Capsule, seed within the proper integument compressed 

 only on two sides? oval, acute, of a dark brown colour. 

 Corculum inverted, flat and erect. Radicle exserted, 

 straight, obtuse, in a direction contrary to the peduncle. 

 Cotyledones large, oboval, green. Perisperm small, farina, 

 ceous, extremely white, scarcely covering the seed lobes. 

 Stature, Stem about three feet high. Boot-leaves four 

 to six inches long and one inch broad. Conspicuous stem 

 leaves about an inch long, extreme involucrate leaves 

 scarcely half an inch. It begins to flower the second year 

 in July and xA.ugust, the flowers are whitish; it does not 

 appear to endure more than from seven to ten years, 

 and is perfectly proliferous never sending off" surculi or 

 lateral stems.
