62 PLANTZ FENDLERIANE, 
obovatis compressis ; areolis orbiculatig fusco-setosis margine inferiore aculeos robustos 
1~35 rectos compressos inzequales fuscos apice pallidiores plerumque deflexos gerentibus 
rariusve nudis ; /ovario obconico areolis sub-30 tomento pallide fusco instructis, superiori- 
bus albo-setosis ; sepalis interioribus sub-20 late obovatis retusis seu emarginatis ; petalis 
10-13 obovatis retusis seu emarginatis ; stigmatibus 5-7 suberectis stamina vix supe- 
rantibus $ bacca obovato-pyriformi nuda. — On rocky hills about Santa Fé, and on the 
Rio Grande, very common ; flowering in May and June. This appears to be the most 
’eenorthern form of the Opuntiz with yellow or brown and flattened spines, which belong to 
" the section of O. Tuna. Another species, with larger joints and larger fruit, occurs in 
FOND) Prec tory s Texas. — Some specimens before me are prostrate, with ascending branches ; the joints 
5 or 5} inches long, and 32 or 4 wide; areole an inch distant from each other, most of 
them bearing stout spines; the lower sometimes only one, the upper from two to five, 
but mostly three or four: one or two are directed upwards, the other and stouter ones 
more or less downward. Larger spines 13 to 2 inches long, dark brown with lighter 
tips; the smaller from half an inch to one inch long, whitish. ~ Another specimen 
has larger, more orbiculate joints, from six to eight inches long, and five or six wide; 
the spines fewer, all directed downwards, or on many areole none at all. The flowers 
which have been distributed under this number are two or two and a half inches in diam- 
eter: ovary about one inch long: sepals yellow with red: petals yellow: stamens red or 
yellow: stigmas apparently green. The fruit which Mr. Fendler says belongs to this 
species is about/half ¥4 inch long, red, smooth, apparently juicy when fresh; the seeds 
ofen.three lines in diameter, margined like those of O. vulgaris, — Several other Opun- 
ti with compressed joints, some of them with fleshy, others with dry and spiny fruit, 
some of them very spiny, and others almost destitute of spines, have been collected by 
a description is 
not here attempted. ; 
251. O. cravara, Engelm. in Wisliz. Rep. not. 12. Plains around Santa Fé; 
never found on the mountains; flowering in June. —I add to the description already 
published, that the areole are very large and closely approximate. From nine to 
eleven smaller and narrower spines are directed upwards or radiating; about six of 
them are turned downward, and are larger and longer; the former are from two to 
four, or even six or eight, lines long; the latter are from six to fourteen lines long. 
The joints form a large and spreading, level-topped mass, which attains the diameter 
of several feet. 
252. QO. arporescens, Engelm. 1. c. not. 5. Hills and elevated plains, from Bent’s 
Fort on the Arkansas to Santa Fe ; flowering in June.— About five feet high, sometimes
