long, the tube twice the length of the limb, hairy at base within: sta- 
mens glabrous: stigma minutely 3-lobed: bracts linear-subulate, as long 
as the glabrous fruit. Wenatchee Washington. : 
2 PLECTRITIS Lindl. Bot. Reg. t. 1095. 
Low smooth annuals with opposite mostly entire leaves and 
small flowers in terminal heads or spikes. Calyx-limb truncate, 
entire or obsolete; tube of the corolla gibbous anteriorly, spurred 
at base; the limb 5-cleft, more or less bilabiate. Stamens 3. 
Stigma capitate. Fruit with a coriaceous, somewhat triangular, 
fertile cell, the two empty ones often open their full length, each 
forming an involute wing; in one species almost wingless. 
* Fruit somewhat meniscoidal, only obtusely angled dorsally: cotyl- 
edons incumbent, that is parallel to the ventral face and expanded 
wings. 
P. macrocera T. & G FI. ii, 50. stems slender, 2-I0 inches high, 
simple or sparingly branched: flowers small, usually in 2-4 somewhat dis- 
tant and spicately disposed verticillastrate clusters: corolla narrow, white 
or pinkish, 1-2 lines long with a- spur usually as long as the tube: limb 
somewhat equally spreading, hardly bilabiate, or equally 4-lobed and the 
osterior lobe emarginate-bifid: fruit glabrous or puberulent, obtuse or 
Fightly lineate-sulcate on the dorsal angle, the broad wing circumscribing 
the ventral face of the achene, spreading or incurved. On dry hillsides, 
British Columbia to California, Nevada and Arizona. 
* * Fruit strongly carinate-angled dorsally: cotyledons transverse to 
the ventral face, accumbent 
+ Wings conspicuous, more or less introrse, in the last species 
small. 
P. congesta DC Prodr iv, 631. Stems often rather stout, 4-20 
inches high,.simple or sparingly branched: flowers 1-4 lines long ina 
capituliform or oblong simple or interrupted thyrsus, or sparingly verticil- 
lastrate below: corolla rose or flesh color with o' viously bilabiate lim» 
and spur half or less the length of the very gibbous throat: fruit broadly 
winged and with prominent but rather obtuse keel, glabrous or puberu- 
lent to short villous. On moist, usually shady slopes, British Columbia to 
California. 
P. anomala Suksdorf Valerianella anomala Gray Stems stoutish, 8- 
20 inches high, freely branching: flowers small, in several approximate 
verticillastrate clusters; corolla white, a line long, wholly destitute of 
spur, at most a small mammeform gibbosity near the base of the short 
and broadly funnelform throat; limb small, obscurely bilahiate, usually 
4-lobed and posterior lobe emurginate or 2-cleft: fruit 144 lines long, 
acutely angled, with sharp edge on the back, with broad wings usually in- 
flexed at base and expanding above. In moist meadows and woodlands 
along the lower Columbia River . 
P. aphanoptera Suksdorf Valerianella aphanoptera Gray. Stems 
slender and weak, 1-2 feet high, branching: flowers small, in 2-4 verticel- 
lastrate clusters: corolla only a line long, white, with obviously bilabiate 
limb and short basal spur; fruit puberulent or glabrate, trigonous ; dorsal 
angle salient but rather obtuse, lateral angles with distinct but narrow in- 
curved wings. Along streams, Southern Oregon. * 
+ + Wings wholly wanting to the triquetrous fruit, the lateral 
angle of which resembles the dorsal. ;
