 Rocks, on the Upper Guadaloupe ; in flower ; and in high 

 rocky prairies on the Salado River ; in fruit, October, (585.) 

 — This interesting accession to our flora has also been found 

 on the Rio Grande by Mr. Wright, and in Northern Mexico, 

 by Dr. Gregg. Since the figure above cited was published, 

 the plant has flowered in the Cambridge Botanic Garden. I 

 must remark that the cinnabar-colored corolla is convolute 

 and erect, not at all spreading at any period, as is represented 

 in the figure, which was made from a dried specimen. The 

 plant is suffruticose, with a thickened ligneous root.

358. V. rupestris, Scheele in Linncea, 21. p. 591. V. 

 populifolia, Lindh. ined. Dry, rocky bed of the Cibolo, 

 Upper Guadaloupe, and other streams ; also in rocky prairies 

 on the Pierdenales ; flowering in May ; the fruit ripe in July, 

 August, and September. — Like his other species, this is by 



inches long, half an inch or less in width, and much like those of Sphaeralcea angusti- 

 folia. The peduncles are remarkably long and slender, and curved towards the apex, 

 near the articulation, so that the flower and fruit are pendulous. The calyx is 5-cleft 

 to the middle ; the lobes rather obtuse. The expanded corolla is only about four lines 

 in diameter. It is said by Mr. Wright to be " blue ; " in the dried specimens it is 

 dark purple. — The species is probably allied to S. venusta, Schlecht. 



S. cuneifolia (sp. nov.): cano-tomentosa, humilis; caulibus e basi fruticulosa 

 assurgentibus ramosissimis ; foliis parvulis rotundato-cuneiformibus flabellato 3 - 5-ner- 

 viis crenato-dentatis repandisve utrinque concoloribus ; stipulis linearibus petiolum 

 subcequantibus; floribus (flavia) brevissime pedunculatis folio brevioribus ; carpellis 

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

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

 of Eagle Pass, on the Rio Grande, September, Mr. Charles Wright. — A well-marked, 

 low, procumbent species, in foliage and habit not unlike 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 some- 

 times scarcely exceed the petioles. The yellow corolla is twice the length of the ca- 

 lyx, and is half an inch in diameter when expanded. The ovate carpels are membra- 

 naceous, slightly inflated ; the seed is proportionally large and spherical, as in Abuti- 

 lon, with the micropyle somewhat rostellate.
