﻿PLANTS FENDLERIANJE. 5 



+ 10. Delphinium azureum, Michx. Between Bent's Fort and Santa Fe ; in bottoms. 



11. D. azureum, var. with greenish blue flowers. Banks of the Mora River. 



12. Actjea rubra, Willd. Damp, shady places in the mountains around Santa Fe. 

 ^13. Thalictrum Fendleri (Engelm. Mss.) : dioicum ; foliis petiolatis ; petiolulis pri- 



mariis brachiatis vel refractis stipellatis; foliolis cordato-rotundatis trilobis; filamentis 

 apice vix incrassatis ; antheris setigero-mucronatis ; carpcllis scssilibus oblique ovatis com- 

 planatis costatis carinato-alatis stjlo recurvo triplo longioribus ; ca;t. fere T. Cornuti. — 

 With the last. (T. Cornuti, of which a few specimens gathered on the Mora River were 

 distributed with this species, has the fruit terete, with the prominent ribs all equal.) 



BERBERIDACE^E. 



' 14. Berberis (Mahonia) Aquifolium, Pursh, Fl. 1. p. 219. t. 4. Mountains; 

 upper part of Santa Fe Creek. " Calyx 6-bracteolate." Engelm. 



f 15. Berberis Fendleri (sp. nov.) : nitidissima ; ramis vernicosis ; spinis 3- 5-par- 

 titis ; foliis oblanceolatis oblongisve muticis subintegerrimis utrinque lucidis ; racemis 

 pendulis densifloris folia multo excedentibus ; bracteolis calyculi sepalis dimidio brevio- 

 ribus ; petalis acutiusculis ; baccis immaturis subglobosis 2-3-spermis. — Santa Fe 

 Creek, at the foot of steep and rocky banks, near the water. Shrubs three to four feet 

 high, flowering at the end of May. — A beautiful and very distinct species, allied to B. 

 Canadensis ; but with the numerous and crowded golden flowers fully as large as those 

 of B. vulgaris : the conspicuous calyculate bractlets tinged with red or pink. Branches 

 brown, remarkably smooth and shining, as if varnished. The leaves are also lucid ; those 

 of the clusters from 6 to 18 lines long, and quite entire, or with few obsolete teeth ; 

 but the cauline appear to be sparingly spinulose-serrate. 



PAPAVERACE^. 



s 16. Argemone hispida (sp. nov.) : radice perenni ; caule crasso foliisque profunde 

 pinnatifidis pube brevi cinerea undique tectis et (nervis marginibusque praesertim) seto- 

 sissimis ; calyce aculeato ; corolla alba maxima ; capsula cylindrica (2-unciali) acutata 

 spinis validis setisque horrida. — Low, sandy places around Santa Fe ; the stems 1 to 

 2 feet high, growing socially in great numbers ; June, July. (Also on the Upper Arkan- 

 sas, &c., Fremont, Wislizenus.) — The flower is 3 or 4 inches in diameter, and accords 

 with Dr. Lindley's figure of A. grandiflora, excepting the prickly calyx. That is a gla- 

 brous plant, while ours is not only densely setose, but is hoary throughout with a short 

 and close hirsute pubescence. The pod is covered with very strong spines, of which the 

 larger are often branched, and also with smaller prickles and a hoary and bristly pubes- 

 cence. A. Mexicana was also collected, in two forms.
