lance-linear mostly dentate, several times longer than the tube and exceeding the tube of the corolla ; corolla shallow, 
wide open, 4 times wider than deep, divided to the middle or beyond ; lobes ovate acute spreading or at length 
reflexed ; capsule erect ovate or turbinate as long as the connivent calyx lobes or his opening at top.— C. Langs-

Common in subalpine meadows, near streamlete, at an elevation of oes. ra feet, Colorado; Clear Creek 
valley, Middle and South Parks. The large and very shallow flowers of a reddish-purple color and the filiform 
branching rootstocks distinguish this species at once from C. uniflora with which I had united it (this journal, 6, 238 
The usually erect stems become sometimes decumbent and several-flowered when overgrown. C. uniflora is- found 
only on bare alpine slopes, usually with Dryas and Silene acaulis, at about 12,000 to 13,000 feet alt. It

THE BLACK-FRUITED CRATMGI, AND A NEW SPECIES. 
We know within the limits of our flora of two black-fruited Crategi, both from the western half of the [127] 
continent. Mr. G, W. Letterman has now discovered a third one along Red River. These three species may be 
rope eteten from our ordinary red-fruited ones, to be designated as Sect. Hrythrocarpus, as Sect. Melanocarpus, 
may be characterized by their black or black-purple or bluish fruit; leaves, at least at first, appressed hairy [128] 
on the upper and glabrous on the cd — flowers in corymbs, styles usually 5; spines mostly short and 
stout, often recurved. The three species a 
C. Dovenast, Lindl., the coueiiiee species, from British Columbia to California, with broader, thinner 
doubly serrate leaves, the upper ones on the shoots lobed, and with broad, incised-toothed stipules ; calyx lobes usually 
entire ; fruit smaller, black-purple, ripe (in Northern California) in August; nutlets 2 to 3 lines long, strongly ridged 
on the back; spines } to 1 inch long. . 
C. rnivuLaris, Nutt., in the Rocky and Wahsatch Mountains of Colorado and Utah, with narrower, more rigid, 
lanceolate-ovate, singly serrate leaves, only the upper ones of the shoots broader, doubly serrate or rarely slightly 
incised, with narrow glandular-incised stipules; calyx lobes usually glandular; fruit larger; nutlets 3 lines long or 
over, usually strongly ridged on the back; spines few, } to 1 inch long. 
. BRACHYACANTHA, Sargent & Engelm. A tree 20 to 30 feet high, or sometimes larger, with smoothish or, in 
very old trunks, rough bark; spines on the whitish branches numerous, stout, short (3 to 6 or 8 lines long), mostly 
curved, sometimes terminating the branches; leaves lanceolate-oblong to ovate or rhombic, 1} to 2 or 23 inches long, 
attenuate into a short petiole, thick and almost coriaceous, appressed-serrate, shining, with ribs almost obliterated, 
those of the terminal shoots larger, broader, slightly lobed, with large foliaceous dentate or subentire stipules;! flowers 
small for the genus, with broadly lanceolate entire calyx lobes and 5 styles; fruit depressed globose, about 4 inch 
through, black-blue with bloom; nutlets (3 lines long) with two slight grooves on the nearly smooth 
In the Red River region, first collected by Drummond (Louisiana Coll. 1832, No. 105 in part); Webster Parish, 
La., C. Mohr, 1880, both without flower or fruit; Concord, Texas, C. S. Sar gent, March 29, 1881, with flower buds; 
west of Longview, Texas, G. W. Letterman, Aug. 19, 1882, with mature fruit, ‘‘ they looked from a distance like plum 
trees with small blue fruit, the ground under them was covered with the fallen haws.” The species is easily recog- 
nized by its coriaceous, shining, almost ribless leaves; in C. Douglasii they are broader, membranaceous, and dull, in 
C. rivularis intermediate between the two. 
I may add here that Prof. Sargent rediscovered the obscure C. berberifolia, Torr. & Gray, which was founded 
on a single flowerless specimen, in the very region, near Opelousas, Western Louisiana, where Dr. Carpenter [129 
1 The stipules of Crategus are not often noticed, and Iam not sure that they possess much constancy or diagnostic value. 
Generally they are found only or at least are most persistent on the shoots; they are always oblique and petioled or stipulate, 
to linear, mostly incised-dentate or sometimes glandular-dentate, rarely entire.
