V. PLANTJ2 WRIGHTIAN-5;. 107 



■\ L. PEDUNcuLARis, var. piCTA ; pube molliore striguloso-cinerea; foliis lyrato- 

 pinnatipartitis, segmentis 5-7, terminali nunc obovato obtuso dentibus obtusis, nunc 

 ovato pinnatifido seu laciniato dentibusque acutatis ; ligulis brevibus brunneo- 

 purpuieis apice fiavis. — Coast of the Gulf of Mexico (near Galveston ■?), Texas. — 

 Difi'ers from the preceding as L. columnaris, var. pulcherrima does from the normal 

 state of that species ; and also in the much less dissected leaves, clothed with a 

 softer and more cinereous pubescence. Yet I conceive it to be only a variety. I 

 have had both forms in cultivation from Mr. Wright's seeds. The naked peduncles 

 are sometimes two feet long. The root is, I believe, annual or biennial. 



328. Heliomeris multiflora, Nutt. in Jour. Acad. (n. ser.) 1. ]). 171; Grai/, PL 

 Fendl. J). S-l. Mountain valley, 30 miles east of El Paso ; Oct. — The same as 

 Gambell's and Fendler's plant. The shorter-leaved variety found by Fremont was 

 also gathered by Burke in the Rocky Mountains. 



329. H. tenuifolia, Grai/, PL Fendl p. 84, adnot. Eocky cliffs of Turkey 

 Creek, June; and valley beyond the Pecos, Aug. Also in the coll. of 1851. — Stem 

 woody, the branches only herbaceous. 



330. SiMsiA (Barrattia) calva. Gray, PL Lindh. 2. |j. 228. Hills near Austin 

 and Turkey Creek, Texas ; June. — The root is tuberous. 



331. S. LAGAsc^FORMis, DC. Prodr. 5. p. 577; Benth. PL Hartw. no. 145: var. 

 glabrior; acheniis sericeis demum glabratis. Valleys in the mountains east of El 

 Paso ; Sept. — Rays very short.* 



332. ViGuiERA coRDiFOLiA (sp. uov.) : caule erecto hispido ; foliis utrinque hir- 

 to-scaberrimis cordatis acutis subsessilibus obsolete serratis rigidis, caulinis omnibus 

 oppositis ; panicula corymbosa nuda oligocephala ; involucri squamis biserialibus 

 coriaceis oblongis acuminatis, exterioribus brevioribus hispidulis, interioribus glabra- 

 tis ; ligulis paucis brevibus ; receptaculo planiusculo ; paleis lanceolatis cuspidatis ; 

 acheniis adpresse sericeis. — Plains at the base of the Guadalupe Mountains, near 

 a fine spring ; Oct. — Stem two or three feet high, stout, leafy to the top. Leaves 

 about three inches long and two in width, acute or acuminate, strongly three-ribbed 

 at the base, veiny, very rough. Peduncles an inch or less in length. Heads half 

 an inch long. Palese of the receptacle as long as the disk-flowers, smooth, pun- 

 gently pointed. Awns of the pappus paleaceous, subulate, nearly as long as the 

 achenium ; the short palese two or three interposed on each side, truncate, denticu- 

 late or incised. — Evidently related to V. sessilifolia, DC. 



* To Simsia also belongs, I believe, the Helianthus amplexicaulis, DC. ! Prodr. 5. p. 5S9. The spe- 

 cies are not well defined : but the subjoined appears to be an exceedingly well-marked new species : — 



SiBisiA SANGUINEA (sp. nov.) : parce hispida ; caule ramoso, ramis gracilibus oligocephalis ; foliis fere 

 omnibus alternis basi auriculata sessilibus scabris, caulinis trilobis lobis dentatis, ramealibus lanceolatis at 

 linearibus integerrimis ; involucri squamis lanceolato-subulatis caudato-acuminatis ; ligulis 10-12 oblongis 

 sanguineis ; paleis receptaculi cuspidatis corollisque disci apice rubro tinctis ; acheniis obcordato-ovalibus 

 planis breviter 1 - 2-aristatis. — Mountains, Mexico (in the temperate region), Ghiesbrechf, No. 305 (v. 

 sp. herb. Mus. Par.): also collected by Galeotti. — The heads are fully half an inch in diameter ; the 

 scales of the involucre glandular-scabrous and very sparingly hispid ; the deep red ligules four lines long. 

 Achenia two or three lines long, appressed-pubescent, soon nearly glabrous, flat, wingless ; the awns small, 

 terete, one of them usually a line long, the other shorter, often very short or obsolete.
