' 247. C. coccineus, Engelm. 1. c, sub Echinocereo. Higher mountains about Santa 

 Fe; often in large clusters of 8 or 15 heads ; flowering in May. — The areolae are hardly 

 oval, but almost orbicular, and are distinguished from those of most related species by 

 their large size. — Among a number of plants of this family which Mr. Fendler sent 

 from Santa Fe in a living state, but which unfortunately were all dead when they came 

 to hand, are some specimens which appear to be varieties of this species, viz. : — 

 £. melanacanthus : aculeis radialibus 10-12 cinereis, centrali longissimo atrofusco 

 porrecto recto seu leviter deorsum curvato. — y. cylindricus: subsimplex, cylindricus; 

 aculeis 8 radialibus, singulo robustiori porrecto. 



248. C. triglochidiatus, Engelm. I. c, sub Echinocereo. Higher mountains about 

 Santa Fe ; also in gravelly soil on the lower hills ; flowering in May and June. — To 

 the description given in Wislizenus's Report I will add here, that the spines are often 

 somewhat curved; the ridges are sharp, but the grooves between them very wide and 

 shallow ; the areolae widely distant from one another (often over an inch and a quarter), 

 and the expression " areolis sparsis" in the character, ought to be changed to areolis 

 distantibus. 



- 249. C. Fendleri (sp. nov.) : globoso-ovatus, simplex vel e basi proliferus, caespito- 

 sus ; costis 9- 10 obliquis tuberculatis interruptis; areolis orbiculatis approximatis ; acu- 

 leis 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 

 oblongo-linearibus, acutis vel obtusis 16-24; stigmatibus 12- 14 viridibus stamina nu- 

 merosissima vix superantibus. — /3. pauperculus : aculeis robustis abbreviatis, radiali- 

 bus 5-7, centrali subnullo. — Santa Fe, on elevated sandy plains ; flowering in June. — 

 The specimens before me are 2£ inches high, and at the base of the same diameter : the 

 areolae from 4 to 6 lines distant; 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. ft. 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 2i to 3£ inches long and wide, violet-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 vari- 

 able in shape.
