﻿282 Nelson: New Plants from Wyoming 



anthers large, the cells slightly divergent below ; style equalling 

 the stamens ; stigma small, capitate ; ovary pilose-pubescent ; cap- 

 sule emarginate, large, turgid, puberulent, protruding from the cleft 

 side of the calyx. 



Common in the Laramie Hills at 8000 to 9000 feet where it 

 develops early. It seeks the loose, rich soil of the valleys and 

 slopes among the sage-brush. It has the habit of W. rubra 

 (Dougl.) Greene and is easily mistaken for that species. How- 

 ever, the peculiarity of its calyx alone will easily separate it. 

 Distributed by me under the name Syntkyris rubra Dougl. as nos. 

 2g and 1 242. Type specimens in Herb. University of Wyoming. 



WULFEXIA GY.MXOCARPA. 



Perennial from a short rootstock bearing numerous fascicled 

 roots ; stems simple, 1-3 from each rootstock, curved ascending, 

 puberulent or soft -pubescent, 1-3 dm. long ; radical leaves numer- 

 ous, petioled, mostly ovate-oblong, rounded at base or rarely sub- 

 cordate, from coarsely to obscurely crenate-denticulate, glabrate 

 or puberulent ; cauline leaves sessile, small, from ovate to oblong- 

 lanceolate, smaller and narrower upward where they pass into the 

 bracts ; spike short and crowded, 3-8 cm. long, pilose-pubescent, 

 bracts from broadly lanceolate at base of spike to linear at sum- 

 mit ; calyx reduced to three, or more usually to two sepals, these 

 on the posterior side, the anterior face of the pistil being naked ; 

 sepals distinct to the base or occasionally united one-third of their 

 length, linear-lanceolate, soft-pubescent ; corolla wanting ; stamen^ 

 but little longer than the sepals, apparently often unequal, anthers 

 small, the cells not divaricate : ovary pubescent, style long, equal- 

 ling the stamens but with the development of the capsule carried 

 out beyond them ; capsule orbicular, much flattened at maturity, 

 equalling or longer than the style, naked but for the slender bract 

 and sepals closely approximated on its posterior angle. 



Like the preceding, this has the general habit of W. rubra. 

 It is with some hesitation that I add two more species in which the 

 corolla is wanting, to the genus Wulfaiia. But these two certainly 

 lend strength to Dr. Greene's contention * that the number of 

 calyx-lobes cannot in this group be used as a diagnostic character
