Plants with a stout naked cylindrical caucex, terminated by a tall 
leafy flowering stem with crowded linear hooked-spiny leaves, dicecious 
flowers in dense racemes forming a narrow compound panicle, oblong: 
obovate obtuse perianth segments, exserted stamens, short style, and 
triangular 3-winged 1-celled 1-seeded coriaceous indehiscent truit with 
obtusely triangular seed. 
1. D. Texanum Scheele. Caudex 6 to 15 dm. high, bearing a dense rosette of leaves 
and a flowering stem 24 to 30 dm. high: leaves light green, 6 to 12 dm. long and 8 to

rulate and toothed, the dilated base gradually narrowed and entire: panicle (6 to 
9dm. long) very narrow; partial panicles erect or suberect (Jem. long), equaling the 
broad subtending bracts; floral bracts broadly ovate, acute, lacerately toothed : peri- 
anth 2mm. long: fruit broadly elliptical (6 to 7 mm. long), short pedicellate, with 
the narrow wings continued above and adnate to the style.—Arid and stony slopes 
throughout western Texas. 
2. D. graminifolium Zuce. Like the last, but with base of the shorter glaucous 
leaves abruptly contracted and spiny-toothed above, thicker staminate spikes, body 
of fruit less attenuate above and wings tree from the style.—Hills and table-lands

13. POLYGONATUM L. (SoLoMon’s SEAL.) 
- Perennial herbs, with simple erect or curving stems trom creeping 
thick knotted rootstocks, nearly sessile half-clasping nerved leaves, 
axillary nodding greenish tlowers, oblong-cylindrieal perianth lobed 
at summit, included stamens, slender deciduous style, obtuse stigina, 
and a globular black or blue 1 or 2-seeded_ berry. 
1. P. biflorum (Walt.) Ell. (SMALLER SOLOMON’S SEAL.) Glabrous, except the 
ovate-oblong or lanceolate-oblong neatly sessile leaves, which are commonly minutely

(nostly 2)- flowered: perianth & to 12 mm. long: filaments papillose-roughened, 
inserted toward the summit of the perianth. (Convallaria hitlora Walt.)—Wooded 
hillsides of northern Texas. 
2. P. giganteum Diet. (GREAT SOLOMON’s SEAL.) Glabrous throughout: stem 
stout, 6 to 2ldm, high: leaves ovate, partly clasping (7 to 20 em, long), or the upper 
oblong and nearly sessile: peduncles several (2 to &)-tlowered: flowers 10 to 18 mm, 
long: filaments smooth and naked, inserted on the middle of the tube.—River 
banks of northern Texas. 
14. UNIFOLIUM Adans. (FAtse SoLomon’s SEAL.) 
Perennial herbs, with simple stems from a creeping rootstock, alter-

1. U.racemosum (L.) Britton. Minutely pubescent, 8 to9dm. high; leaves numer-
