known from where obtained,) shows that to be identical with a Texan species, common between the Brazos and Nueces rivers, which I have described in Engelmann and Gray's Plantae Linheimerianae, Boston Journal of Natural History, v, page 247, under the name of Cereus caespitosus, and which should now be named Echinocereus caespitosus. Echinopsis pectinara, β. laevior, Monv., and γ. Reichenbachiana, Salm, are perhaps forms of this Texan plant, which varies considerably in its native country. Dr. Wislizenus has sent me a living specimen and dried flowers of E. pectinatus; unfortunately the plant met with a similar fate to those sent to England by Mr. Potts, and there is none now in cultivation, if I am correctly informed; but I preserve the dried specimen in my herbarium, and have been enabled to draw up from it the description.[1]

Bachimpa, south of Chihuahua; flowers in April. Stem 7 inches high, below 312, above 212 inches in diameter; upper and lower spines 2 lines, lateral 4 lines long; central spines mostly 3, sometimes 2, and below as much as 5, in one vertical row, to 1 line in length. Flowers about 3 inches long and wide; red or purple, spiny bristles on the tube 2 to 3 lines long; the uppermost 3 to 5 lines long, only 3 to 5 together.
It will not be amiss to introduce here again a more complete and correct description of its Texan relative.

From the Brazos to the Nueces, in Texas, Lindheimer; flowers in May and June; generally 1 to 2 inches high, and of nearly the same diameter; rarely as much as 5 or 6 inches high, and 2 to 312 inches in diameter; longer lateral spines in different specimens 2 to 4 lines long; flowers in the northern specimens, from Industry, 2 inches long and wide, in those from New Braunfels 2 to 3 inches in diameter and length; generally a little wider than long when fully open. Brown or black bristles on the tube 2 to 5 or 6 lines long, surrounded by wool, which is often 3 lines in length.
