++ 4+ Stems erect: leaves mainly linear or linear-lanceolate, obtuse at both ends and short- 
petioled or sessile. 
6. S. Neo-Mexicana Gray. Minutely puberulent, not cinereous, 1 to 3 dm. high: 
diffusely many-stemmed from a woody base: peduncles not articulated, all short or 
very short: petals orange-yellow often changing to red: carpels without beak or 
cusps, or barely mucronulate, (S. Elliottit, var.? Gray.)—Extreme western Texas 
and adjacent New Mexico and Mexico. 
7. §. Lindheimeri Engelm. & Gray. Cinereous-puberulent, at least the lower 
leat-surface: slender peduncles about equaling the leaves, articulated above the 
middle: petals yellow: carpels bicuspidate.—Southern and eastern Texas, from the 
Rio Grande to the Colorado and Louisiana. 
8. S. longipes Gray. Somewhat scabrous-pubescent: peduncles very long and 
strict, becoming 7.5 to 15 em. long, 3 or 4 times longer than the leaves, articulated 
alictle below the summit: petals orange: carpels without beak or cusp.—All along 
the southern border of Texas. Discovered many years ago in southwestern Texas, 
its range has been recently extended eastward by its discovery in Duval County. 
++ + Calyx not at all angled: flowers long-peduncled and petals violet. 
9. &. filipes Gray. Canescent, 6 to 9 dm. high: leaves lanceolate, cordate at base, 
dentate-serrate, velvety-pubescent above, tomentose beneath: peduncles long and 
slender, 5 to 7.5.em. long, a little longer than the leaves, articulated near the small 
pendulous flower: carpels reticulate-rugose and without beak or cusp.—Hills, be- 
tween the Colorado and the Pecos. 
** * Calyx naked, enlarging much around or under the fruit, membranaceous or scarious. 
10, S. physocalyx Gray. Stems numerous from a thick base, decumbent, strigose: 
leaves thickish, ovate-oblong, crenate-dentate, subcordate at base: calyx 5-parted, 
membranaceous-inflated, winged, with broadly ovate or cordate divisions: corolla 
inconspicuous, yellow: carpels 10, thin-walled, reticulated, and with a beak-like 
apex.—Abundant in the valleys and prairies of southern and western Texas. 
7. ANODA Cav. 
Similar to Sida, except that the carpels are combined into a radiate- 
spreading fruit, subtended by the spreading persistent calyx. 
1. A. hastata Cav. Commonly with some hispid (but no stellate) pubescence: 
leaves hastate or deltoid: peduncles slender and axillary, exceeding the leaves: 
petals violet or purple (varying to white), 6 to 12 mm. long: the much depressed 
fruit mostly surpassed by the widely spreading calyx, the top beset by scattered sim- 
ple bristles; carpels 15 to 20, rather conspicuously beaked: seeds naked (including 
A, cristata Sehlecht).—A Mexican species found in the mountains of extreme south- 
western Texas. 
2. A. Wrightii Gray. Pubescence minute and stellate, with some simple soft- 
hirsute hairs above, viscidulous: lowest leaves ovate and coarsely crenate, the others 
oblong-ovate or triangular-lanceolate : peduncles exceeding the leaves, upper flowers 
naked-racemose: calyx shorter-lobed, less widely spreading, and hardly surpassing 
the densely and stellately hirsute much depressed fruit: petals yellow, about 10 mm, 
long: carpels 8 to 10, beaked: seeds barely puberulent (wrongly referred to 4. par- 
viflora Cav.).—Dry ravines and rocky places along the upper Rio Grande and the 
Limpia. 
3. A. pentaschista Gray. Slender, 3 to 6 dm. high, minutely puberulent and 
more or less cinereous with stellate-pubescence : lower leaves ovate or subcordate, 
somewhat 3-lobed: upper hastate or lanceolate, uppermost linear: calyx 4 mm. long, 
ascending or appressed to and seldom surpassing the little depressed puberulent fruit, 
little shorter than the yellow corolla: carpels 5 (rarely 6 to 10), obscurely beaked:
