about 2 mm. wide, triangular-acute with sessile stigma, very flat, 

 with seeds conspicuously in two rows and many and small. Flow- 

 ers about 5 mm. long, erect, light-colored. Petals oblaneeolate, a- 

 bout twice the purplish sepals. Subalpine on dry ridges of Mt. 

 Belknap Utah, June 1898-K To this I would refer material from 

 Santa Fee N. M. by I. E. Diehl, but this has much narrower and 

 longer pods, longer pedicels, and may be A. Fendleri. 



Arabis lignifera Nelson. I had given this another name. It is 

 a loosely caespitose perennial with small crowns and rather woody 

 but short brunches of the slender and erect tap root. Stems about 

 1 dm. long, filiform, ascending and simple from the base of the 

 crown and independent of the sterile and leafy crown adjoining 

 which becomes the stem producer of the next year. Leaves spatu- 

 late to oblanceolate, thick, with evident midrib, about 1.5 cm. 

 long, acutish, entire, about 3 mm. wide, densely pubescent with 

 compact, and much-branched minute hairs, the slender petiole as 

 long as the blade. Stem leaves narrowly oblong, acute, sessile, 

 the upper ones smooth and minutely and acutely eared, about 1 

 cm. long. Upper part of stem naked. Flowers few, about 5 mm. 

 long, lidit-colored. the petals purplish and about twice as long as 

 the sepals. Pedicels nearly 3 mm \oug, ascending but arcuate at 

 tip so Unit the arcuate pod is nearly pendent or rarely horizontal. 

 Pods rarely over 3-4 at the end of the peduncles, about 3 cm. long, 

 1.5 mm. wide, shortly acute with sessile stigma, very flat, seeds 

 rather few, oval, appearing as if in a single row, very narrowly

Cymopterus corrugatus var. scopulicola n. var. 

 A close ally to 0. globosus also, and like it with deep-seated, erect 

 and tuberous fusiform roots, mostly with a single crown. Leaves 

 leathery, rather glaucous. Flowers wake, opening in very early 

 spring, the fruit maturing in lay. Koot <.)15 cm. long and about 

 1,5 cm. wide, crowned by several hyaline sheaths from which the 

 purple and slender and mostly single stems arise 2-10 cm long
