V. PLANT.E WRIGHTIAN^. 19 



subsequantibus ; floribus (flavis) brevissime pedunculatis folio brevioribus ; carpellis 

 5 pubescentibus membranaceis turgidis apice inter rostra brevia mollia demum bi- 

 valvibus ; semine globoso. — In subsaline soil, Texas, about thirty-five miles north- 

 east of Eagle Pass, on the Rio Grande ; September. — A well-marked, low, procum- 

 bent species, in foliage and habit not u.nlike a Hermannia. The soft, downy leaves 

 are only about half an inch in length and breadth, on petioles of three or four lines 

 long ; the flowers are solitary, or often clustered in the axils, and sometimes scarce- 

 ly exceed the petioles. The yellow corolla is twice the length of the calyx, and is 

 half an inch in diameter when expanded. The ovate carpels are membranaceous, 

 slightly inflated ; the seed is proportionally large and spherical, as in Abutilon, 

 with the micropyle somewhat rostellate. — Gray, PL Lindh. 2. p. 165. adnot. 



49. S. FiLiPES : furfuraceo-canescens ; caule erecto gracili herbaceo e radice 

 perenni ; foliis brevissime petiolatis lanceolatis basi cordatis dentato-serratis obtu- 

 siusculis supra velutino-pubescentibus subtus ramulisque cano-tomentosis nunc 

 fulvis vel ferrugineis ; stipulis setaceis petiokim excedentibus ; pedunculis unifloris 

 capillaribus (2-3-pollicaribus) foliis longioribus paulo sub flore pendulo articulatis ; 

 corolla purpurea calycem subduplo superante ; carpellis 7 reticulato-rugosis muticis 

 superne pubescentibus dorso canaliculatis bivalvibus. Gray, PL Lindh. 2. p. 164. 

 adnot. — Hills of Turkey Creek, near Austin, Texas. Very near, I fear, to S. ve- 

 nusta, Schleckt, from Mexico. 



50. S. LONGiPES (sp. nov.) : pubero-scabrella ; caule gracili stricto e radice lignes- 

 cente ; tuberculis infrafoliaribus nullis ; foliis linearibus imisve lanceolatis longiuscule 

 petiolatis utrinque obtusis superioribus crebre serratis, serraturis juniorum glandu- 

 losis ; stipulis setaceis petiolo multum brevioribus ; pedunculis solitariis elongatis 

 unifloris, fructiferis folia ter-quaterve superantibus ; corolla aurantiaca calyce duplo 

 longiore ; carpellis 10 acutis erostratis omnino muticis. — Prairies of Live Oak 

 Creek, June; mostly in fruit. — Stem 6 to 18 inches high. Leaves 1^-2 inches 

 long, one or two lines wide, or the lower 6 or 8 lines wide, and only repand-serrate, 

 canescently puberulent beneath ; the petioles of the lower ones half the length of 

 the blade. Fructiferous peduncles 3-6 inches long, erect. Flowers as large as 

 those of S. Lindheimeri. Carpels nearly smooth on the back, obtusely somewhat 

 pointed at the apex, but not at all rostrate, aristate, nor bimucronate, dorsally de- 

 hiscent at the apex. — This is probably the same as No. 830 of Coulter's Mexican 

 collection, from Zimapan, and I think I have seen it in other collections from that re- 

 gion. I had supposed it might be S. linearis, Cav. ; but the short peduncles, small 

 flowers, and spinose tubercle under the leaves, which that species is represented to 

 have, point to a plant like S. angustifolia, Lam.* only with more numerous and 



* S. heterocarpa, Engelm. in PL Lindh. 2. 2>- 163 (note), is this cosmopolite S. angustifolia, Lam. (S. 

 minor, McFadyen in herb. Hook.), which Planchon, perhaps with good reason, considers only a variety 

 of S. spinosa. The awns or cusps of the carpels vary much in length. 



S. glabra, Niitt., is the same as S, stipulata, Cav. (also S. Balbisiana, DC), and not distinct from S. acu- 

 ta, Burm., DC. ; a species now widely scattered over the warmer parts of the world. Varieties of it (S. 

 glabra 0. ? &c. Torr. ^ Gray, Fl.) from Key West and East Florida are distributed by Mr. Shuttleworth 

 under the name of S. carpinifolia, Linn. f. var. .' The S. carpinifolia is a related but distinct species, 

 with smooth and even, biaristate carpels.
