CACTEA OF PLANTA FENDLERIANA. 115 
249. C. FENDLERI, sp. nov.: globoso-ovatus, simplex vel e basi proliferus, caspitosus ; costis 9-10 obliquis 
tuberculatis interruptis ; areolis orbiculatis approximatis ; aculeis basi bulbosis robustis, radialibus sub-7 compressis 
subincurvis fuscis demum cinereis (tribus inferioribus longioribus, superioribus brevioribus, summo nullo); aculeo 
centrali robustiore longiore teretiusculo sursum curvato atro-fusco ; floribus campanulatis; tubo pulvillis sub-30 albo- 
tomentosis stipato, inferioribus aculeos setaceos albos apice adustos 8-12 radiales et singulum centralem, superioribus 
aculeos sub-3 robustiores longiores curvatos albos gerentibus ; ; sepalis interioribus 12-15 lineari-lanceolatis acutis ; 
petalis See game eas acutis vel obtusis 16-24; stigmatibus 12-14 viridibus stamina numeronsans vix supe- 
rantibus. — 8. PA CULUS: has robustis abbreviatis, radialibus 5-7, seach subnullo. — San , on elevated 
sandy plains ; Pere in June. — The specimens before me are 2} inches high, and at the base of the same diameter; 
the areolz from 4 to 6 lines dotaak ; the lower radial spines 7 to 10, the upper from 3 or 4 to 6 lines long ; central 
spine somewhat erect, curved upwards, 10 to 15 lines long. In var 8. the spines are all from 3 to 6 lines long. The 
upper spine is wanting in all my specimens, and the opposite lowest one is longer than any except the central spine. 
Flowers from 24 to 3} inches long and wide, vivlet-purple. The spines on the lower part of the tube are from 2} to 3, 
and on the upper from 3 to 5 lines long. Petals variable in shape. 
250. OPUNTIA PHAIACANTHA, sp. : diffusa ; articulis obovatis seu orbiculato-obovatis compressis; [52] 
areolis orbiculatis fusco-setosis margine satiate aculeos robustos 1-5 rectos compressos inzequales fuscos apice 
pallidiores plerumque deflexos garenitititis rariusve nudis; ovario obconico areolis sub-30 tomento pallide fusco 
instructis, superioribus albo-setosis ; sepalis interioribus sub-20 late obovatis retusis seu emarginatis; petalis 10-13 
tusis seu emarginatis; stigmatibus 5-7 suberectis stamina vix superantibus; 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 a most northern form of the Opuntiz with yellow or brown and fattened spines, which belong to the 
section of 0. Tuna. Another species, with larger joints and larger fruit, occurs in Texas. — Some specimens before 
me are prostrate, with ascending branches; the joints 5 or 5} ares long and 34 or 4 wide ; areole an inch distant 
from each other, most of them bearing stout spines; the lower sometimes only 1, the upper from 2 to 5, but mostly 
3 or 4; one or two are directed agen, the other and stouter ones more or lees downward. Larger spines 1} to 2 
inches long, dark brown with lighter tips ; the smaller from } inch to 1 inch long, whitish. — Another specimen has 
larger, more orbiculate joints, from 6 to 8 inches long and 5 or 6 wide ; the spines fewer, all directed downwards, or 
areole none at all; The flowers which have been distributed under this number are 2 or 24 inches in 
on ny 
diameter; ovary about 1 inch long; sepals yellow with red; petals yellow; stamens red 0 low ; oe 
apparently green. The fruit which Mr. Fendler says belongs to this species is about half an fidks Jig red, smoo 
apparently juicy when fresh ; the seeds often 3 lines i in diameter, margined like those of O. vulgaris everal sane 
Opuntize z with compressed joints, some of them with fleshy, others with dry and spiny baa wae - them very 
pd and others almost Fein of spines, —have been collected by Mr. Fendler about Santa Fé; but for want of 
complete materials, a description is not here attempted. 
251. O. CLAVATA, ‘te eres ae in Wislizenus’s Report, note 12. Plains hae Santa Fé, — never found on the 
mountains; flowering in e, —I add to the description already published, that the areole are very large and closely 
pater imate. From 9 to il ‘ocular and narrower spines are a upw a or radiating; about 6 of them are 
wnward, and are larger and longer ; the former are fro o 4, or even 6 or 8, ne long; the latter are 
ia 6 ts 14 lines long. The joints form a large and spreading, ia ae mass, which attains the diameter of 
several feet. e 
52. O. ARBORESCENS, Engelm. l. c., note 5. Hills and elevated plains, from Bent’s Fort, on the 
Arkansas, to Santa Fé; flowering in June. — About 5 feet high, sometimes as much as 5 inches in diameter [53] 
below ; the older stems and branches terete ; the younger joints strongly tuberculated. Spines often an inch 
long ; generally from 15 to 25 in each fascicle.
