ter radiating and much surpassing it: axillary clusters of hairs short and soft: 
petals copper-colored or buff: seeds blackish, granulate-tuberculate, with metallic 
luster.—Plains of western Texas. 
5. P. pilosa L. Annual, the base often hardening with age: leaves linear-subu- 
late, 6 to 12 mm. long, with copious axillary hairs: petals carmine, crimson, or pur- 
ple, 2 to 4 mm. long: seeds blackish, muriculate-granulose, with metallic luster.— 
Throughout Texas, and by far the commonest species. 
6. P. parvula Gray. Annual, but sometimes fleshy-rooted, depressed and diffuse : 
leaves oblong-linear, obtuse, 4 to 10 mm, long, with copious axillary hairs: petals 
yellow and copper-colored, barely 2 mm, long: seeds pale red, minutely granulate.— 
Plains of western Texas, where it has been mistaken for P. pilosa. 
2. TALINOPSIS Gray. 
Shrubby and smooth, with slender branches, fleshy linear nearly 
terete leaves, a few-flowered terminal cyme of purple flowers, 2 ovate 
membranaceous persistent sepals, 5 petals, numerous stamens, a short 
3-cleft style, a fusiform 3-valved pod, and numerous hooked seeds. 
1. T. frutescens Gray. About 6 dm. high, smooth except the minute axillary 
hairs: leaves 12 to 24 mm. long, scarcely 2mm. wide: cyme few-flowered, with short 
angled articulated branches: flowers closely sessile in the forks and readily falling 
away in dried specimens: pod nearly 24 mm. long, covered except the tapering sum- 
mit by the persistent (becoming) scarious calyx.—-Bluffs and high mesas along or 
near the Rio Grande to New Mexico. 
3. TALINUM Adans. 
Low glabrous herbs (sometimes suffrutescent), with mostly fleshy 
leaves, 2 herbaceous ovate concave deciduous sepals, 5 ephemeral petals, 
5 to 30 stamens, a 3-lobed style, and a subglobose 3-valved pod with 
numerous shining carunculate seeds. 
* Leafy plants with flat leaves and flowers in an ample panicle. 
1. T. patens Willd. Stem slender, erect: leaves oblanceolate-spatulate, shortly 
cuspidate, 5 to 7.5 cm, long: flowers rose-colored or yellow: bracts small, ovate and 
cuspidate : seeds tuberculate. (T. reflexum Cav. T. spathulatum Engelm.)—Rocky 
banks, hillsides, or dry prairies, along or near the Rio Grande from the 100th meridian 
westward. Var. SARMENTOSUM Gray (TL. sarmento sum Eng.) is a procumbent form 
apparently more common than the species. 
** Leafy plants with flattish leaves and solitary axillary lowers. 
2, T. lineare HBK. Stem ascending, much branched : leaves lanceolate or linear- 
lanceolate, 3.5 to 7.5 em. long: peduncles reflexed in fruit: flowers orange to red: 
seeds beautifully marked with curved ridges and transverse striw. (7. aurantiacum 
Engelm.)—On rocky soil or prairies, abundant everywhere west of the Pecos and 
extending through southern Texas to the Gulf. The tuberous root is edible when 
cooked. 
** * Flowers in mostly naked cymes on terminal slender naked peduncles much surpassing 
the terete linear leaves. 
3. T. calycinum Engelm. Stems at length branching: leaves elongated, 3.5 to 5 
cm, long: flowers 20 to 30 mm, in diameter: sepals ovate-orbicular, cuspidate, tardily 
deciduous: petals pink, twice as long as the calyx : stamens 30 or more: style twice 
longer than the stamens, declined.—In sandy soil, western Texas (Gillespie County 
and northward).
