mutata Torr. Mex. Bound., not Roem. & Sch.)--Southern and western Texas. At 
Bejar Berlandier collected var. BERLANDIERI Gray, which is perhaps a depauperate

lanceolate or ovate-lanceolate and lopger (giving a somewhat hastate outline), lateral 
divisions often 2-lobed or 2 or 3-cleft; peduncles only 2.5 em. long,

from the more rigid base: seeds glabrous: stems twining: root annual, 
13. I. trichocarpa Ell. Hirsute-pubescent or glabrate: leaves cordate, some en-

from the Gulf States to Texas, at least as far west as Gillespie County (Jermy), 
14. I. lacunosa L. Slightly pubescent or hirsute, or nearly glabrous: leaves as 
the preceding or less lobed, more commonly ovate-cordate and entire, conspicuously 
acuminate: peduncles shorter: pod more pilose.—River banks and low grounds,

15. I. Wrightii Gray. Leaves all digitately divided into 5 narrowly lanceolate 
entire leaflets (all 2.5 to 3.5 cm. long, or the lateral shorter): peduncles 1-flowered, 
not exceeding petiole: sepals very obtuse: corolla pink or purple, 12mm. long: pod 
&8mm.long: seeds globular, minutely and densely puberulent.—Probably from south- 
ern Texas (Wright). 
16. I. cardiophylla Gray. Leaves broadly cordate and with basal lobes some- 
what incurved, entire, acuminate: peduncles mostly 1-flowered and shorter than 
petiole: sepals acute, thickish but scarious-margined, more or less muricate-glandu- 
lar on the back: corolla purple, 18 mm. long: pod 12 mm. long: seeds oval, brownish- 
puberulent.—Western borders of Texas, in mountains near El Paso (Wright),

leaves or their divisions all linear or narrower and entire. 
17. I. leptophylla Torr. Very glabrous: stems erect or ascending (6 to 12 dm,
