lent between the veins, more densely and villously so on the 

 veins ; rachis with the same indument, showing here and there 

 a small stout prickle near the insertion of the leaflets ; stipules 

 small, velvety- puberulent, glandless and entire marginally : 

 fruits corymbose, subglobose, glabrous, glaucous, crowned 

 with the persistent villous sepals, these erect and even con- 



nivent- 



This also is known to me only as collected by myself while 

 on my extensive journeyings in the Northwest in the summer 

 and autumn of 1889. On the whole journey I gave close 

 attention to the roses, making specimens as perfect as possible. 

 R. anacantha V72is obtained at Takoma, Washington, 24 Aug., 

 1889. Its habitat was along the borders of thickets near the 

 salt marshes, at a point not then far out of town. Type sheet

Three New Rhamni. 



Rhamnus Blumeri. Small tree of the Frangula group, 

 with subcoriaceous foliage and only tardily deciduous ; grow- 

 ing twigs canescently velvety- tomentulose, even the older 

 branchlets grayish with the same indument still persistent : 



leaves mostly round-oval, iM to 25^ inches long, 1 to 1/4 



inches broad, obtuse at both ends, or with a short blunt apical 

 cusp, nearly entire, the teeth both small and obscure, lower 

 face more or less pale with fine tomentellous indument, the 

 upper green, scaberulous-looking under a lens, yet soft to the 

 touch : berries globose, black ; seeds 2, exactly orbicular, low- 

 hemispherical, olive-green. 



Collected in the Chiricahui Mountains, southern Arizona, at 

 5300 feet, 28 Aug., 1906, by J. C. Blumer ; his n. 1290 as in 

 U. S. Herb. The seeds appear to be constantly two only, of 

 course by abortion of one ovule ; and they are circular in 

 periphery, as well as quite perfectly plano-convex. The small 

 tree has no intimate connection, either geographically or phy-
