ing, with 5 compressed ribs, dark green, with whitish areolae, and 

 about 8 short dusky spines. 

 ■ The specimen figured here is very remarkable on account of the 

 fruit, which was unknown to me. Provided the drawing is correct, 

 we have here a smooth oval acuminate fruit crowned with \he re- 

 mains of the corolla, and supported by a distinct stipe of a bright 

 crimson color; A stipe, as well as such an acumination, I have not 

 seen in any other fruit of a cactus. Fruit, with the long acumina- 

 tion, 2^ inches long, | to 1 inch in diameter, stipe about | inch 

 long. ' . 



7. Opuntia. "Very abundant on the Del Norte and Gila.'' No 

 date nor statement whether the figure represents the natural size or 

 is smaller, ' 



The species belongs to the section elliptic^ of Salm, it is ascend- 

 ing, older stems prostrate, branches and younger joints erect, 8 — 10 

 inches high; joints orbicular obovate, rounded, obtuse or some- 

 times acutish, of ai bluish green color, 1^ to 2\ inches long, and 

 little less wide; spines short and whitish; berries obovate, scarlet, 

 only about 3 or 4 inches long. If the figure represents the natural 

 size, this species ought to bear the name O. microcarpa. 



8. Opuntia, *^ October SSth, 1846, common on the Gila." Much 

 branched, sub-erect, joints obovate, often acutish, purplish, with 

 two or three longer brown spines directed downwards; fruits obo- 

 vate, red. In the figure, the joints are 1| — 2 inches long, and 1—1$ 

 "^ide; fruit about 3 lines long. 



There are several opuntiee known with purple colored joints, but 

 ^one in the least resembling this, and I must consider it as a dis- 

 tinct species to whichi would give the name of 0. violacea. 



9. Opuntia? '* October 22d, 1846. Abundant on the Del Norte 

 and Gila." A remarkable plant apparently more like a niammila' 

 '^^(^ than like an opuntia. The fruit "is also represented without 

 ^reolae^ or tubercles, exactly like the smooth fruit of a mammilaria; 

 ^ut this may be an oversight in the artist. The habit of the plant 

 suggests the belief that it is an opuntia of the section cylindracea. 



Joints or brandies ascending, cylindrical, tuberculated, 4 — 6 in- 

 cbes long. 1 — ii inches in diameter; tubercles very prominent, 

 ^ith about 8 long (1—1^ inches) straight spines; fruits obovate, 

 ^mbilicate, scarlet,^towards the top of the branches, about 9 lines 

 long) and 6 in diameter. 



It is a distinct species which I am gratified to dedicate to the 

 skilful artist who has drawn all these figures, Mr. J. M. Stanly, I 

 therefore propose for it the name opuntia Stanlyi, 



.10. O^unh'a. "November 3d, 1846, 4 feet high." Stem erect, 

 ^ith verticillate horizontal, or somewhat pendulous branches; 

 branches cylindrical, strongly tuberculated, about 8 lines in diam- 

 eter, ^ith short" spines on the tubercles; fruit pale yellow, clavate, 

 tuberculate, umbilicate, 1 to 11 inches lono^, 6— S lines in .diameter.
