 transition into Malvastrum grossularisefolium (Sida grossularisefolia, Hook. 8f Am.). 

 Bed of the Limpia River ; Aug. 



t M. cocciNEDM, a more canescent variety, with narrow divisions to the leaves, 

 approaching the var. dissectum. Valley of the Limpia ; Aug.

 stipulis subulatis ; floribus sparsis axillaribus et secus ramulos laxe racemosis ;

 Lindh. 2. j}. 160 (adnot.). — Dry soil along the Rio Grande near Presidio ; also 

 on hills near El Paso. — The New Mexican specimens are decidedly suffruticose. 

 Stems 6-12 inches high, much branched, much more slender than in M. coccine- 

 um ; the flowers smaller and paler (between a buff and a brick-color). The leaves 

 are not canescent, but green and sparsely stellate-hirsute, and their segments incised 

 or almost pinnatifid ; the lobes are tipped with a deciduous mucro or short seta. 



X M. LEPTOPHYLLUM * (sp. nov.) : pube tenui lepidoto-stellata incanum ; caulibus e 

 basi lignescente plurimis adscendentibus spithamieis gracilibus ; foliis inferioribus 

 petiolatis trisectis, segmentis et foliis superioribus sessilibus anguste linearibus sic- 

 cate involutis nunc filiformibus integerrimis ; stipulis minimis caducis ; bracteolis 

 2-3 setaceis caducis; lobis calycis triangulatis tubo ajquilongis ; carpellis renifor- 

 mibus muticis. — Between W. Texas and El Paso, New Mexico, 1851. — Whole 

 plant silvery-canescent with a fine and close lepidote-stellate pubescence : a great 

 number of slender stems arising from a thickened woody base, bearing at the sum- 

 mit a few racemose flowers, which are smaller than those of M. pedatifidum. Up- 

 per leaves, and lobes of the lower trisected leaves, from 6 to 9 lines long. Calyx 

 5 -cleft to the middle, the lobes ovate-triangular, shorter and less acute than those of 

 M. pedatifidum. Corolla brick-red, half an inch in diameter. Carpels 9 or 10, 

 tomentulose, reniform, beakless and pointless, forming a depressed umbilicate cap- 

 sule, shorter than the calyx.

 found by Mr. Trecul on the Nueces and Rio Grande, Texas.) Again collected by 

 Mr. Wright during the past season, with fine fruit. — Stems a span to a foot high,

 in a second journey from Texas to New Mexico, while attached to the corps of Colonel Graham, then 

 surveyor of the Mexican boundary.
