68 ERYTHEA. 



the axils of the leaf-like bracts (only the upper bracts small and 

 inconspicuous), the whole densely yellowish setose- h ai ry : sepals 

 linear, erect, closely approximate so that the calyx appears tubular, 

 8-10 mm. long, longer in fruit: corolla tube slender, exceeding the 

 calyx by J-|, its lobes only |— | as long as the tube: stamens 

 dimorphic, antliers linear, about 3 mm. long, nutlets ovate, obtuse, 

 3-4 ram. long, acute angled, slightly keeled on the back, somewhat 

 obscurely transversely rugose and low papillate towards the margins. 

 A very strongly marked species with somewhat the habit of 0. 

 thyrsijlora Greene but never to be confused with that or any of the 

 related species on account of its long, tubular calyx, its long corolla 

 tube and short lobes, and its characteristic pubescence. Perhaps it 

 will help to locate it to say that it is somewhat intermedislte 

 between 0. fulvocanescens (Gray) Greene and 0. humilis (Gray) 

 Greene, from both of which it differs both in foliage, pubescence 

 and inflorescence. Collected by Prof. C. S. Crandall, at Palisades, 

 Mesa Co., Colo., May 14, 1898, and distributed as Eritrichium ful- 

 vocanescens Gray. Type in Herb. University of Wyoming. 



Cryptanthe ramulosissima. Densely and intricately 

 branched from the base upward, the whole forming a sub-spherical 

 mass 2-4 dm. in diameter, in autumn probably becoming a "tumble- 

 weed" by the snapping of the slender tap-root, densely hispid 

 throughout: leaves small, very numerous, linear, green, the sparse 

 hairs with pustulate bases: spikes very numerous, densely flowered, 

 uniserial, but the flowers arranged in pairs: sepals setose-hispid, 

 linear with midrib slightly thickened at base, 5-6 mm. long, the 

 tips open or spreading; nutlets smooth, sub-conical, somewhat acu- 

 minate, 2 mm. long, the narrow ventral groove widening slightly 

 /toward the base and terminating in an open areola, usually all four 

 maturing. 



This species is most nearly related to C. Fendleri (Gray) Greene, 

 but its remarkably branched habit will at once separate it from that 

 and more distinctively yet from C. Pattersoni (Gray) Greene. It is 

 separated also by the less thickened sepals, the slender branchlets, 

 and somewhat paired flowers. 



It was found in considerable abundance at Laramie, the type 

 being No. 5275, Sept. 6, 1898.
