** Leaves lanceolate to oblong or ovate : Jlowers (so far as known) not white. 
5. P. puberula Gray. With short cinereous pubescence: stems erect from a woody 
base: leaves linear or lanceolate or the lowest oblong, mucronate, short-petioled ; 
flowers ‘ purple,” pendulous in elongated loose racemes : wings broadly obovate and 
ciliolate ; no crest: pods oval, smooth, slightly ciliate on the margins: a somewhat 
lacerate or lobed searious short bonnet-shaped caruncle capping the summit of the 
retrorsely-hairy seed.—In the mountains of extreme western Texas and reported as 
far east as Coleman County and the Leona River. 
6. P. macradenia Gray. Low and shrubby, cinereous with soft pubescence, and 
thickly beset with leaves which are oblong or oblong-lanceolate, obtuse, nerveless, 
pellucid punctate with conspicuous glands, and but 4 to6mm. long: flowers solitary, 
extra-axillary, short-peduncled: no crest: pod ovate, cinereous and often dotted 
with glands: seed very villous and capped by a short pubescent caruncle.—On stony 
hills, reported from scattered stations throughout southern and western Texas. 
7, P. ovalifolia DC. Soft pubescent, diffusely branching from a woody base: 
leaves thickish, broadly ovate or ovate-oblong, obtuse, or acutish above, with revo- 
lute margins, 10 to 20 mm, long: flowers greenish-yellow, in short loose-flowered 
racemes: wings oblong, pubescent; the ample conspicuous keel with no crest : pod 
nearly round, with smooth face and conspicuously ciliate margins: caruncle short 
and bonnet-shaped.—Hills of southern and western Texas. 
8. P. Lindheimeri Gray. Pubeseent: stems branching, a little woody at base, 
from a long woody red root: leaves coriaceous, minutely pubescent but shining, con- 
spicuously reticulated on both surfaces, the lowest obovate, becoming ovate, oblong, 
or lanceolate above, 10 to 20 mm. long: racemes loosely flowered, with a zigzag 
rhachis and 3 small persistent bracts at each joint: keel with a conspicuous straight 
spur in place of a crest: pod elliptical, puberulent: caruncle 2-spurred, half as long 
as the sericeous secd,—Rocky hills and cliffs of southern and western Texas. 
2. KRAMERIA Linn. 
Small shrubs or woody perennial herbs, silky-tomentose and often 
prostrate, with alternate and entire narrow leaves, solitary purplish 
flowers on axillary bracted peduncles, 5 more or less petal-like sepals, 
5 unequal petals (3 upper iong-clawed and approximate, 2 lower short, 
sessile and tleshy), 4 stamens united below, 2-celled anthers dehiscing 
obliquely near the apex, and a globose coriaceous indehiscent spinose 
or muricate 1-seeded pod. 
1. K. parvifolia Benth. A rigid diffusely branched shrub 3 to 6 dm. high, with 
silky appressed pubescence, the slender divaricate branchlets often spinose: leaves 
linear, 8 to 16mm. long, the lower obtuse, the upper spiny-tipped: flowers 4 to 8 
mm. long: peduncles with 2 or 3 pairs of leaf-like bracts: the ovate silky sepals pur- 
ple within: fruit with numerous very slender prickles retrorsely barbed their whole 
length, cordate-globose, 8 mm. long.—Common in southern and western Texas. 
2. K. ramosissima Watson. Like the last: shrubby and divaricately much 
branched, canescent: leaves linear-lanceolate, 2 to 4 mm. long, often fascicled in the 
axils: flowers “light maroon”: fruit ovate, silky-pubescent, with slender very acute 
naked spines about 1 mm. long. (K. parvifolia, var. ramosissima Gray.)—Common 
in southern and western Texas. 
3. K. canescens Gray. Similar in habit to the two preceding species: pubescence 
short and tomentose: leaves lanceolate to linear : peduncles shorter, 2-bracted : sepals 
lancvolate, the smaller one linear: fruit ovate-globose, tipped with the stout curved 
style, and armed with slender prickles barbed at apex.—Common in southern and 
western Texas, and said to be particularly abundant in the “Great Bend” of the
