7. KRYNITZKIA Fisch. & Meyer. 
Usually hispid annuals or perennials, with small white flowers, 
5-parted or deeply cleft calyx erect or little spreading in fruit, short 
corolla usually with more or less fornicate throat, and erect and straight 
unarmed nutlets attached to the gynobase (axis or receptacle) either at 
inner edge of base or ventrally from the base upward. 
* Nutlets ovate, with rounded back, attached next the base to the low and convex or depressed 
pyranidal gynobase: flowers racemose, white, mostly bracteate. 
1. K. heliotropioides Gray. Softly strigose-hirsute and (at least when young) 
canescent: leaves linear, the lower mainly opposite: flowers scattered, on filiform 
pedicels much longer than the calyx, the lobes of which are oblong-linear: corolla 
With conspicuous crests in the throat: scar of nutlets large and sessile. (Hrilrichium 
heliotropioides Torr, Mex, Bound, Antiphytum heliotropioides A, DC.)—On the Mexi- 
can side of the Rio Grande (San Carlos), but doubtless also in Texas. 
2. K. floribunda Gray. Cinereous with fine and close and with a coarser nearly 
hispid pubescence: leaves perhaps all alternate, narrowly linear, upper gradually 
diminished to bracts: flowers very short-pediceled, in short panicled racemes or 
spikes: calyx-lobes linear-lanceolate, acuminate: corolla not appendaged in the 
throat: scar of nutlets small and slightly stipitate. (Lritrichium floribundum Torr, 
Antiphytum floribundum Gray.)—Southwestern Texas, beyond the Pecos, 
** Nutiels attached by ventral angle or groove from base up at least one-third or one-half 
or the whole length to an elevated gynobase, the back conver and not keeled, and 
sides wingless : corolla small and white, with tube not surpassing the calyx: flowers 
almost always sessile and scorpivid-spicate. 
+ Nutlets either dissimilar or only one maturing, strictly inclosed in the rigid fructiferous 
calyx, the midribs of which are much thickened and indurated: diffusely branched and 
rough-hispid. 
3. K. crassisepala Gray. Leaves oblanceolate and linear-spatulate: flowers short- 
pediceled, many or most of them bracteate: calyx-lobes greatly thickened below in 
fruit: nutlets dissimilar, 3 of them muricate and one larger and smooth or nearly so, 
(Lritrichium crassisepalum Torr. & Gray.)—Plains of western Texas. 
4. K. Texana Gray. Leaves obovate-oblong or spatulate, or the uppermost linear: 
flowers nearly sessile: spikes mostly leafless: calyx in fruit separating by an articu- 
lation: but one nutlet usually maturing, which is smooth or nearly so. (Hritrichium 
Teranum A, DC.)--From near Austin and westward, at least to Gillespie County 
(Jermy). 
++ Nutlets all fertile and alike: midrib of calyx-lobes not thickened. 
5. K. pusilla Gray. Low and slender, 5 to 7.5 em, high, rough-hispid: linear leaves 
mostly clustered at the root: flowers rather crowded in small spikes; crests in throat 
of corolla inconspicuous: nutlets attached at lower half, with strongly granulate 
rounded back bordered by acute angles and very smooth inner faces. (Eritrichium 
pusiilum Torr. & Gray.)—Northwestern borders of Texas. 
6, K.ramosa Gray. Larger and stouter, roughish-hispid, even the loose panicu- 
late spikes mostly leafy: leaves linear: flowers rather scattered: crests in throat of 
corolla rather conspicuous: nutlets attached at lower half, coarsely granulate round 
to the deeply excavated scar and without lateral angles, (Hritrichiwn ramosum A. DC, 
HE, hispidum Buckley,)—Plains and sandy banks of western Texas. Calyx closed at 
maturity and deciduous with the inclosed fruit, like a bur, 
7. K. micrantha Gray. Slender, 5 to 12.5 em. high, hirsute-canescent: leaves 
linear, only 4 to 8mm, long: flowers in the forks, and much crowded in short leaty 
spikes: corolla barely 2 mm, high, obscurely appendaged at throat: nutlets at- 
tached for their whole length, smooth or minutely papillose, and with roundish mar- 
gins. (Lritrichium micranthum Torr.)—Dry plains, western border of Texas,
