flowers 2 or 3 in the axils: calyx-lobes (pistillate) elliptical, obtuse, white-margined : 
glands 3, strap-shaped or 2-parted: styles 2-lobed: pod small: seeds smooth, slightly 
ribbed lengthwise.—Texas. 
4. P. lathyroides, var. commutatus Muell. Branches round filiform: leaves 
dense, oblong-ovate, subacuminate, oblique at base, more or less glaucous, 7 to8 mm. 
long: filaments united in a slender column, shortly trifid at apex.—Southwestern 
Texas and Mexico. 
4. ANDRACHNE L. 
Low and shrubby plants, with rather virgate spreading and leafy 
branches, alternate entire stipulate leaves, monw@cious axillary long- 
pedicelled flowers, 5 or 6-lobed calyx, rather distinet petals, 5 or 6 free 
stamens with cleft anthers, 3 styles (united below) with capitate stig- 
nas, 3-celled substipitate pod, and rugose ecarunculate seeds. 
1. A. phyllanthoides (Nutt.) Branches terete, slender and glabrous: leaves 12 
to 17 mm, long, 10 to 15 mm. broad, obovate, membranaceous, glabrous, little longer 
than the internodes; stipules ovate-lanceolate, pilose: flowers on glabrous capillary 
pedicels (1 em, long): calyx-lobes oblong-obovate: petals of the staminate flowers nar- 
rowly obovate and 3 to 5-toothed, of the pistillate minute and entire. (Lepidanthus 
phyllanthoides Nutt. A. Rameriana Muell.)—Extending into Texas from Arkansas and 
Indian Territory. 
2, A. Reverchoni. More or less hirsute, with 2 or3 very slender stems (3 to6Gdm, 
high) froma thick base, densely leafy: leaves thick, pale, orbicular (12 to 16 mm. 
in diameter), twice the length of the internodes, usually emarginate, subcordate at 
base, hirsute beneath (and above on midrib); stipules ovate-lanceolate, ciliate: 
salyx-lobes obovate: petals of the pistillate flowers minute and entire, of the stam- 
inate oblong-obvate and slightly dentate.—Rocky prairies, Mustang Creek, Johnson 
County, Reverchon, distributed as 4d. Rameriana, May. According to description 
the resemblance is close to 4. Telephioides, var. rotundifolia Muell, of the eastern 
Mediterranean region, 
5. JATROPHA L. 
Perennial herbaceous or shrubby plants, with alternate mostly 
long-petioled palmately veined stipulate leaves, moncecious flowers in 
terminal open forking cymes, corolla-like calyx (staminate d-lobed, 
pistillate 4-lobed), corolla of 5 distinct or apparently united petals 
or none, glands of the disk opposite the calyx-lobes, 10 to 30 stamens 
in two or more whorls with filaments monadelphous at base, 3 styles 
(united below) with summits once or twice forked, and the 3-celled pod 
(separating into 3 two-valved carpels) with 3 carunculate seeds. 
* Petals present: flowers fasciculate. 
1. J. spathulata Muell. Erect and shrubby: leaves subsessile, subfasciculate, 
narrow : flowers in numerous cushions of many scale-like bracts: staminate calyx with 
lanceolate-ovate subacute lobes, pistillate with lanceolate acuminate lobes: petals 
evolute, lanceolate, obtuse, united beyond the middle: ovary acute: styles thick, 
unequally 2-lobed, united into a column,—San Diego, Var. SESSILIFLORA Muell, 
has linear to obovate-spatulate obtuse and emarginate to acute leaves (2.5 to 5 em, 
long), and white flowers, the staminate being sessile or subsessile.—Common on the 
gravelly blufts of the Rio Grande, and the ravines and mountains of western Texas. 
2. J. macrorhiza Benth. Perennial: stems about 3 dm. high, from a thick fleshy 
rootstock, subsimple, with the inflorescence and nerves of the leaves pubescent or
