44 Piper : New and noteworthy Northwestern Plants 



narrowed below : stigmas and ovary-cells always three : ovules 

 solitary in the cells.

Washington : Klikitat County, near the mouth of Klikitat 

 River, Suksdorf, no. 991, May and June, 1890. 

 Oregon: Waldo, Hoivell, no. 204, June, 1884. 

 This species is rather intermediate between G. cotnlaefoha 



Steud. and G. iutertexta Steud. but nearer the latter. 



' Phacelia lenta 



Erect, stout, 2 dm. tall, densely glandular-puberulent through- 

 out and sparsely hirsute : radical leaves oblong in outline, 5—6 cm. 

 long, pinnately parted into about 9 lobes, these coarsely few- 

 toothed, the stout petioles nearly equaling the blade ; cauline 

 leaves few, similar, but short-petioled ; inflorescence a panicle of 

 rather loose secund false racemes, 8 cm. long, by half as broad, 

 the lateral racemes about 5 -flowered ; calyx-lobes somewhat un- 

 equal, rather broadly oblong or oblanceolate, obtuse, ciliate as well 

 as glandular, 6 mm. long : corolla apparently white, campanulate, 

 cleft to the middle : stamens, pistil and capsule just as in P. sencea 

 Gray. 



Bare hills of the Columbia River, Wash., Brandegee, no. 976* 

 May, 1883. 



Very closely related to P. sericea Gray, from which its much 

 broader calyx-lobes, looser inflorescence and glandular pubescence 

 seem clearly to distinguish it. The single specimen examined is 

 rather fragmentary.

Lappula arida 



Perennial, erect, 3-5 dm. tall, branched above, canescently 

 hirsute throughout, the pubescence mostly appressed : radical leaves 

 linear or narrowly lanceolate, acute, attenuate into a petiole, 8-20 

 cm. long, 5-8 mm. wide ; cauline linear, 4-12 cm. long, 5 mm. 

 wide, sessile by a broad base, all more or less hirsutely ciliate : 

 racemes loosely flowered, 5-10 cm. long : calyx-lobes linear-ob- 

 long, very obtuse, 2 mm. long: corolla white, rotate, 10-12 mm- 

 in diameter ; the fornices broader than long, not retuse, short pilose: 

 marginal prickles of the nutlets united at base, all glochidiate at 

 apex, one-half as long as the width of the nutlet, usually more or 

 less incurved ; the dorsal surface muriculate and with 6-10 cen- 

 trally placed short glochidiate bristles ; inner face minutely hispid 

 or muriculate, the scar central. 



This species has quite the aspect of L. ciliata Greene, which is 

 abundant on gravelly hillsides near Spokane. The latter species
