208 Mr. J. Micro on the Tribe Colletiesc. 



canaliculate, deflexo ; floribus panels, fasciculatis, e tuberculo 

 squamoso majusculo puberulo proficiscentibus ; calyce cylin- 

 drico, 10-nervi, rubello, niedio non constricto, imo carnosulo, 

 limbi laciniis 5 reflexis, 3-nerviis, apice callosis, staminibus 5 

 in sinubus fere sessilibus, disco annulari crenulato, stylo in- 

 cluso. Bolivia, in locis aridis petrosis, Puna ad Lac. Titicaca, 

 altit. 12,000 ped. v. s. in herb. Mus. Paris (Weddell,4391). 



This species much resembles C. atrox in general aspect, but 

 its spines are not so broad and compressed at their base, and 

 are of a more glaucous-yellow hue ; the form of the calyx corre- 

 sponds more with that of C. spinosa in being broad and little 

 constricted. The spines vary in length from 6 to 9 lines, are 

 greatly divaricated or nearly patent, and are decussating, the 

 internodes being 4 to 6 lines apart. The leaves are 3 lines long, 

 1 line broad, thick, coriaceous, convex and channelled above, 

 concave below, with revolute toothed margins ; each pedicel is 

 1 line long; the length of the calyx (including its reflected 

 segments, of nearly 1 line) is 3^ lines, and its diameter 1^ line*.

 presse hirtellis, ad nodos compressis, spinis subbrevibus, 

 validis, subcurvulis, acumine calloso-pungentibus, junioribus

 squamoso prodeuntibus ; pedunculo flore pendulo breviore, 

 calycis tubo rubescente tenuiter membranaceo, 10-nervio, 

 basi tumido, limbi laciniis 5 acutis, reflexis, staminibus in 

 sinubus fere sessilibus, stylo tereti, stigmate capitato-3-lobo, 

 paulo exserto ; capsula sub-3-loba, 3-cocca, cupula calycina, 

 grandefacta, immersa, pisi magnitudine. Huancabamba Altse 

 Peruvise, altit. 10,300 ped. Vernac. Zarza de Moyse. v. s 

 in herb. Mus. Paris (Bonpland) a eel. Kunthii missa. 



This species has a fuscous hue, with short interlaced spinelets : 

 the primary spines are 2 inches long ; the secondary 8-10 lines, 

 and 5 lines apart ; the tertiary spinelets are 3 lines long, very 

 stout, with a sharp point. The leaves are very caducous, and 

 are wanting in the specimen I have seen, but they are described 

 by Kunth. The flowers are small, of a reddish hue, many of 

 them appear sterile, and soon fall off; the segments of the border 

 are nearly as long as the tube, each being about 1 line long ; and
