8 PLANTJE WRIGHTIAN.E. VI. 



ripe, pretty strongly 4-ribbetl, two of the ribs marginal and two lateral, and with four 

 usually less conspicuous ribs alternate with these.* 



Anemone Caroliniana, Walt. ; Ton: «§c Grai/, Fl. 1. p. 12. Mountain ravine 

 near El Paso, April, in fruit. (1304.) 



Myosurus minimus, Linn. Low bottoms of the Rio Grande, at San Elizario ; 

 March. (1:305.) Also gathered on the Rio Santa Maria, Chihuahua, by Dr. Bige- 

 lovv. 



Ranunculus divaricatus, Schrank, Bairsche Fl. 2. p. 104. R. circinnatus, 

 Sihth. Fl. Ox. p. 175; Coss. ^- Germ. Atlas Fl. Par. t. 1. /, 9. R. aquatilis. And. 

 Amer. Bed of the Limpia (June), and of the Mimbres, New Mexico, Aug. 

 (835.) — This is the only species of the section Batrachium that I have seen in the 

 United States. 



R. Cymbalaria, Pursh. ; Ton: Sf Gray, Fl. \. p. 17. Sandy bottom of the Rio 

 Grande, near El Paso ; April, July. (83G.) — This is quite like the plant of the 

 coast of the Northern United States. I doubt if Hartweg's No. 1, and Fendler's 

 No. 7, referred to R. tridentatus, II. B. K., are distinct. 



R. affinis, R. Br.; Hook. Fl. Bor.-Am. 1. p. 12. t. 6 (fig. sinistr.). Hills along 

 the Coppermine Creek, New Mexico ; Aug. (837.) — This is a slender form of the 

 species, quite different from Fendler's No. 8, with the radical leaves deeply cleft or 

 parted, and the cauline mostly 3-parted, into very narrow linear divisions. In 

 these specimens the head of fruit is nearly as short as in R. auricomus ; but the 

 carpels are rounder and less margined. 



R. REPENS, Linn. var. macranthus. Gray, PI. Lindh. 2. p. 141, 8f PL Wright, p. 

 7. R. macranthi;s, Scheele. Margins of the Limpia; June. (838.) — These are 

 taller and stouter plants than those of Lindheimer, on which Scheele founded his 

 R. macranthus, and are particularly remarkable for the great number of densely 

 packed carpels, the edges of which are thicker and the styles longer than in 

 Scheele's plant. Had R. macranthus been founded on the present form, I should 

 hardly have ventured to suppress it; but the fruit of the Texan plant is just that 

 of R. repens, var. Marilandicus ; some genuine specimens of which Mr. "Wright 

 collected on the Mimbres, New Mexico. (839.) 



Delphinium azureum, Mic/u: Along the Limpia, near its head ; Jvuie. • (840). 

 — D. vimineum, Don, is only a coarser-leaved form of the present species, and D. 

 virescens, Nntt., is another. 



D. simplex, Doiiffl. in Hook. Fl. Bor.-Am. 1. p. 25 ; Benth. PL Hartiv. p. 295. 

 Stony hills near the copper mines, Santa Rita del Cobre, New Mexico. (841.) — 

 A pretty large form of the species. — D. VEtriegatum, Torr. Sf Gray (D. grandiflo- 

 rum. Hook. Sf Am. Bot. Beech.), is D. decorum, Benth. PL Hartw. No. 1631, and 

 doubtless also of Fischer and Meyer. 



* Thalictrum debile, Buckley in Sill. Jour. 45. p. 175, or a plant which I can distinguish from it only 

 by the stronger ribs to the fruit, was formerly sparingly gathered in Texas by Mr. Wright, and also at San 

 Felipe by Drummond (Coll. III. No. 3, bis, in herb. Hook.) 



T. clavatum, Hook. Fl. Bor.-A?n. 1. p. 2, non DC. (T. Richardsonii, Gray, in Sill. Jour. 42. p. 17), 

 is the same as T. sparsiflorum, Turcz. ; Ledeb. Fl. Ross. 1. p. 5, as is shown by original specimens m 

 the Hookerian herbarium.
