﻿PLANTS FENDLERIANJE. 53 



as much as five inches in diameter below ; the older stems and branches terete ; the 

 younger joints strongly tuberculated. Spines often an inch long, generally from 15 to 25 

 in each fascicle. 



GROSSULARIACEiE. 



253. Ribes irriguum, Dougl. in Hort. Trans. 7. p. 516. Margin of Santa Fe 

 Creek ; May. — The specimens are in flower only. The pedicels are short, as in R. 

 hirtellum, Michx. (Ton: &• Gray, Fl. I. p. 546), which the plant much resembles ; but 

 the leaves are rounder and more downy, the campanulate calyx is yellowish-green, with 

 no purple tinge, and the spines are triple. The stamens are somewhat longer than the 

 petals, but shorter than the oblong calyx-lobes. These are not mentioned in the publish- 

 ed character of R. irriguum, Dougl. But I am confident that this is the species in ques- 

 tion, as I have the same from the valley of the Kooskooskee, where it appears to abound. 

 According to Mr. Spalding, who sends it, it grows by the water-side, and yields " a most 

 delicious gooseberry or currant, tasting like a plum." The same is in Geyer's collection, 

 (No. 330), in flower, under the name of R. triflorum. The fruit scarcely exceeds a large 

 currant in size, and is perfectly smooth. — From Mr. Spalding I also have characteristic 

 specimens of R. divaricatum, Dougl., which, he remarks, is often twelve feet high, and 

 which is likewise said by Geyer to form " a robust shrub or small tree, 8 to 15 feet high, 

 very thorny; stems 2 to 4 inches in diameter." 



254. R. leptanthum (sp. nov.) : glabrum, esetosum ; spinis subaxillaribus solita- 

 riis validis rarius geminis ternisve ; foliis parvis (4-6 lin. latis) crebris 5-fidis, lobis 

 incisis ; pedunculis brevibus deflexis 1 - 2-floris ; pedicellis subnullis ; bracteis rotundatis 

 ovario brevioribus ; calyce tubuloso gracili extus piloso albido, lobis subspathulatis tubum 

 aequantibus staminibus petalisque integerrimis subduplo longioribus ; stylo glabro indivi- 

 so ; stigmatibus binis ; baccis inermibus glabris. — Rocky banks of the Rio del Norte, 

 and ravines near Santa Fe ; May. — Shrub 3 to 4 feet high. Flower nearly half an inch 

 in length. — Very distinct from any species in the Flora of North America; apparently 

 resembling the R. microphyllum, H. B. K., of Mexico, which, however, is said to have 

 very short peduncles, red flowers, a campanulate calyx, retuse petals, and a 2-cleft 

 style. 



255. R. cereum, Dougl. I. c. ; Torr. Sf Gray! Fl. A. p. oolr (R. pumilum 8t R. 

 reniforme, Nult.! Mss.) Shaded banks of Santa Fe Creek; May, in flower. Shrub 3 

 to 4 feet high. 



f256. R. sp. ; leaves only, of a glutinous species, perhaps merely a form of R. cere- 

 um. Rocky hill-sides, near Santa Fe, and on the Mora River.
