186 LEAFI.ETS. 



subterminal subsessile cymes ; sepals lanceolate and long, yet 

 far from half equalling the long tubiform corolla, the oval 

 obtuse segments of which are of less than one-third the length 

 the tube and erect. 



A diminutive species known to me in but a single sheet in 

 U. S. Herb., of three excellent specimens collected in the Kla- 

 math Valley in southern Oregon almost fifty years since by 

 Dr. H, M. Cronkhite, U. S. A. With its small tubular corollas 

 like those of some dwarf caprifoliaceous shrubs, this would 

 pass at first glance with the uninitiated for a xylosteum or a 

 sy mphor icarpus . 



Apocynum PULCHEI.I.UM. Dwarf and depressed, the stems 

 only 6 to 10 inches long, decumbent, or even for their whole 

 length almost reclining, much branched, puberulent ; leaves 

 mostly spreading horizontally on distinct but short petioles, sel- 

 dom deflexed, oval, obtuse at both ends, the largest only % 

 inch long, /^ inch wide, firm, dark green and glabrous above, 

 pale and sparsely pubescent beneath : cymes numerous, and 

 from several of the upper axils, occasionally, and to the num- 

 ber of 5 or more, panicled above the upper pair of leaves ; 

 pedicels hairy under the calyx, the hairiness extending upwards 

 along the middle of the sepals, these broadly lanceolate, acu- 

 minate: corolla very large, purplish, the tube long and cylin- 

 dric, the lobes nearly as long as the tube, oblong, obtuse, not 

 widely spreading. 



Mountain meadows of Lassen Co., California, collected long 

 ago by Mrs. R. M. Austin. This remarkably beautiful dog- 

 bane is so small, and with such diminutive and rounded foli- 

 age, as to give it the appearance of some small caprifoliaceous 

 plant, a dwarf snowberry, for example. 



Apocynum rotundifolium. Of the size oiA. pulchellum, 

 but upright, branching only fastigiately, and from above the 

 base, glabrous throughout ; lowest leaves almost exactly
