BORAGINACEAE 



long, 3-5 long glochidiate prickles on each side with 1-3 short prickles between, all slightly united at base; 

 dorsal surface muriculate, bearing a few short glochidiate bristles. Rocky sides of canyons, Klickitat River, 

 Klickitat County, Washington. Known only from the type locality. 



Hackelia patens (Nutt.) I. M. Johnston, Journ. Arnold Arb. 16: 194. 1935. (Rochelia patens Nutt. 

 Journ. Acad. Phila. 7: 44. 1834; Lappula coerulescens Rydb. Mem. N.Y. Bot. Card. 1: 328. 1900; L. coeru- 

 lescens var. brevicula Jepson, Fl. Calif. 3: 307. 1943.) Stems 2 or 3, short, deflexed-hirsute, with some hairs 

 spreading, arising from a woody caudex covered with old leaf-bases; basal leaves many, oblanceolate to lanceo- 

 late, stem-leaves reduced upwards, pubescence rather dense, short, appressed; branches of the inflorescence 5-10- 

 flowered, pedicels short, elongating somewhat in fruit; corolla blue or whitish, small, appendages somewhat 

 broader than long, obscurely papillose; nutlets small, marginal glochidiate prickles 3-5 on each side, a few 

 short prickles interspersed, the longest prickles surpassing the body of the nutlet; face of the nutlet with a 

 faint median ridge, muriculate and occasionally bearing 1 or 2 short prickles. Western Montana and Idaho 

 to Utah and Nevada. In California but one specimen (Jepson, Poison Creek, White Mountams, Inyo County), 

 the type of L. coerulescens var. brevicula, has been seen. Until more material is available it seems best to assign it 

 to the species above, to which it is closely related. Type locality: "near the Flat-Head River." Collected by Wyeth.

 bracts broadly ovate, pedicels slender, about 1 cm. long in fruit ; corolla blue, 9-10 mm. broad, 

 appendages subquadrate, papillose, conspicuous ; nutlets 5-6 mm. long, dorsal face broadly ovate, 

 hirsutulous, faintly muriculate, with 6-10 very short prickles, the marginal glochidiate prickles 

 slender, bluish in age, somewhat dilated at base, free or a little united, 9-13 on each side, to
