120 LEAFLETS. 



along the veins : flower-clusters many, simple and racemose, or 

 slightly panicled ; fruiting panicles spreading but not pendu- 

 lous or even nodding : fruit not seen. 



A remarkable species, as seeming ambiguous between the 

 Atlantic and Pacific types of the genus. Mr. Suksdorf, who 

 collects it in rocky places along the Columbia east of the Cascades, 

 and therefore on the borders of the arid region, distributes it for 

 " R. diver siloba" which it certainly is far from being. Its 

 foliage is that of Lobadium, i. e. Schtnaltzia. 



T. COEIACEUM. Very stout rigidly upright stems minutely 

 and sparsely puberuleut and minutely lenticellate : leaves sub- 

 coriaceous or almost hard-coriaceous, dark olive green, pale 

 beneath, both faces almost or quite glabrous ; leaflets very large, 

 ovate to round-ovate, obtuse or acutisb, usually quite entire, 

 only here and there a leaflet with a serrate tooth or two on .one 

 side, the largest and broadest 2 J inches long, 2i inches broad, 

 none much shorter and none narrow : panicles merely ascending, 

 the branches and pedicels short and rigid : fruits of the largest, 

 depressed-globose ; epicarp polished and striate, and under a 

 lens minutely, sparsely, but distinctly hispidulous. 



A single excellent specimen in U. S. Herb, exhibits all the 

 above pronounced specific characters. Its home must be at 

 least on the borders of arid eastern Washington, where it was 

 collected by Mr. Suksdorf in 1885, but just where, the label 

 fails to indicate. 



T. COMABOPHYLLUM. Stems upright, leafy branches light 

 red-brown, obscurely puberulent, well marked with small elliptic 

 lenticels : leaflets obovate-deltoid, the terminal 1 or 2 inches 

 long and petiolulate, the laterals half as large, sessile, all en tire 

 except around and across the nearly truncate apex which is 

 almost as broad as the leaflet's length, here cren ate- toothed, the 

 upper face dark -green, the lower pale, both glabrous : fruit in 

 loose pendulous clusters both notably compressed and elongated, 

 being round-oval, but obtuse, the epicarp very thin and fragile, 

 delicately puberulent : putamen strongly striate. 



Prom Tighe's, near San Diego, Calif., Dr. Edw. Palmer, 1876. 

 The inverse-deltoid leaflets, dentate across the summit, are 

 much like those of most strawberry leaflets ; hence the name.
