slender, 3-4dm. long, leaves scattered along the floral branches, 

 densely clothing their bases, very narrowly linear-oblanceolate, 

 2-3mm. wide, entire or remotely and obscurely denticulate; 

 these as well as the branches cinerous with appressed 2-forked 

 hairs, calyx-lobes 6-7nim. long, petals orange or yellow, cruci- 

 form, pods in rather short lax racemes, on pedicels about 8mm. 

 long, widely spreading, straight or slightly curved upwards, 

 4-angled, 1.5-1. 75mm. broad, 5-6cm. long, beak slender, less 

 than 1mm. broad and but little longer, seeds brownish, about 

 1.5mm. long. 



Quite unlike any known member of this genus in habit, 

 but in fruiting characters closely resembling C. angustatus 

 Greene. 



Common on the sand dumes along the coast between Port 

 Ballona and Redondo. The writer's number 2511, collected at 

 Port Ballona, June 10, 1902, is the type. 



v Cotyledon nudicaule. 



Glaucous and densely covered with a white meal; caudex 

 short, rather stout, about 2cm. thick ; leaves rosalate, numerous 

 ascending, nearly terete, the inner face slightly flattened, 

 tapering to an acute tip ; 5-8cm. long, 4-6mm. thick, slightly 

 dilated at the very base, scapes 15-30cm. high, 2-2. 5mm. thick, 

 with 2 nearly opposite (sometimes abortive) leaf-like bracts a 

 little above the middle, other^dse naked, infloresence in a 

 rather close, much branched cymose panicle, the main branches 

 4cm. long or less, freely branching, each branch and branchlet 

 subtended by a short linear bract, flowers on pedicels 2.5-4mm. 

 long, sepals ovate acutish, 2mm. long, petals white, united at 

 the base, narrowly oblong, acute or somewhat acuminate, 

 6-7mm. long, spreading, white, carpels ovate-oblong, united a 

 short distance above the base, divergent, 4-6mm. long, tipped 

 by the slender style of nearly equal length; seeds few, linear- 

 oblong, acute at both ends, slightly over 1mm. long. 



Nearest C. edulis Nutt, in that it has the spreading petals, 

 but easily distinguished by its mealy herbage, naked flowering 

 branches and rather compact compound panicles. 



Common on rocky clifl^s near the mouth of the San Gabrie^ 

 Canon, Los Angeles County. The author's number, 2652, col- 

 lected July 4, 1902, is the type.
