Lappula echinata Gilib., Fl. Lith. 1:25 (1781). Branching annual; herbage strigose and 

 hispid; leaves linear or oblong; racemes leaf y-bracteate ; corolla bright blue, 1% lines broad; 

 nutlets papillate dorsally and furnished with 2 rows of marginal prickles. — Adventive at Upland, 

 San Bernardino Valley (Bull. S. Cal. Acad. 24:50,-1925). Native of Europe and Asia. 



6. PECTOCARYA DC. 



Low slender obscure annuals with strigose pubescence and narrowly linear 

 leaves. Flowers minute {Yo to 1 liii^ long), wliite. on very short pedicels, scattered 

 along the stems or branches. Calyx deeply 5-cleft, spreading or reflesed in fruit. 

 Corolla with a circle of processes or crests which almost close the throat. Stamens 

 included. Nutlets flat, thin, equably radiate-divergent or divergent in pairs, bor- 

 dered at apex or all around the margin with a row of bristles hooked at tip. — Species 

 6, North and South America. (Greek pectos, combed, and karua. nut, on account 

 of the row of bristles on the nutlet.) 



Nutlets about equably divergent, not winged, cuneate-rhomboid or obovate-rhomboid, the acute 

 margin bordered all around by bristles ; calyx hispidulose and uncinate-bristly at tip of 



lobes, in fruit longer than the nutlets; Coast Eanges and Sierra Nevada foothills 



1. P. pusilla. 

 Nutlets borne in divergent pairs, bordered by a wing ; calj-x-lobes not uncinate-bristly at tip. 

 Nutlets oblong or linear, the wing somewhat coriaceous, more or less beset with uncinate 

 bristles, the body always destitute of uncinate bristles ; calyx shorter than the 

 nutlets. 

 Wing undulate, deltoid-toothed, erosulate or entire, not cleft, the apex thickly beset with 

 slender bristles, the sides naked or furnished with a few similar bristles ; 

 throughout Cal. 



Wing markedly incurved at middle of nutlet, commonly not bristly at middle 



2. P. penicillata. 

 Wing not incurved at middle of nutlet, the sides scattered-bristly or sometimes 



naked 3. P. heterocarpa. 



Wing parted or cleft all around into triangular or subulate teeth, the teeth ending in 

 slender bristles. 

 Nutlets not recurved (sometimes incurved), the body linear-oblong, the teeth of 



the wing triangular or with broad base; cent, and S. Cal 4. P. linearis. 



Nutlets strongly recurved, the body linear, the teeth of the wing subulate ; trans- 

 montane deserts 5. P. recurvata. 



Nutlets (or always some of them) orbicular, the vring thin-searious, entire or obscurely un- 

 dulate, both the body and (commonly) the wing beset with uncinate bristles; calyx 

 in fruit longer than the nutlets ; transmontane deserts (also intramontane in S. Cal.) 

 and South Coast Eanges 6. P. setosa. 



1. P. pusilla Gay. Stem erect, somewhat flexuous, simple or sparingly 

 branched, 3 to 8 inches high, sometimes the brandies many from the base and dif- 

 fuse in age ; herbage strigulose ; leaf -blades linear to oblanceolate, 2 to 7 lines long ;
