 transition into Malvastrum grossulariacfolium (Sida grossulariajfolia, llook. Sf Arfi.), 

 Bed of the Limpia River ; Aug. 



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

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



42. M. PEDATiFiDUM *. suffruticosum ; caulibus diffusis graciUbus ramosis ; foliis tri- 

 partitis profunde trifidisve pilis stellatis parce hirsutis, scgmentis latcralibus bifidis, 

 terminali subtrilobo, omnibus subpinnatifido-incisis, lobulis dentibusve patcntibus; 

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

 bracteolis 3 setaceis ; laciniis calycis triangulato-lanccolatis acuminatis tubo longio- 

 ribus ; carpellis muticis, rostro brcvi complanato membranaceo inflexis. Gmj/, Pl. 

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

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

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

 um ; the ilowers smaller aud palcr (betwc*cn a buff and a brick-color). The leaves 

 are not cancscent, but green and sparsely stellate-hirsutc, and their segmcnts inciscd 

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



X M. LEPTOPiiYLLUM * (sp. uov.) : pubc tcuui lepidoto-stellata incanum ; caulibus e 

 basi lignescente plurimis adscendentibus spithamasis 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 a:quilongis ; carpellis renifor- 

 mibus muticis. — Between W. Texas and EI Paso, New Mcxico, 1851. — "S^TioIc 

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

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

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

 per leaves, and lobes of the Ipwcr 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 dikmcter. Carpels 9 or 10, 

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

 sule, shorter than the calyx. 



43. SpHiERALCEA HASTULATA (sp. nov.) : humilis, hirtello-pubescens ; caulibus 

 herbaceis e basi suffrutescente erectis nunc decumbentibus ; foliis oblongis lanccolar 

 tisve hastato-subtrilobis sinuato-dentatis heteromorphis, junioribus subtus canescen- 

 tibus; floribus longiuscule pedunculatis axillaribus solitariis ad apicem ramorum 

 subracemosis ; lobis calycis triangulato-lanceolatis acutis tubo subduplo longioribus 

 fructiferis capsulam superantibus ; carpellis biovulatis scepius dispermis dorso hirtis 

 mucrone brevi apiculatis. — Prairies beyond the Pecos, Aug. ; in flower. ( Also 

 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, 



Under this mark (J) I introduce some spccies collected by Mr. Wright during the past season (1851),
