CHEILANTHES. 91 



it. Bliime's specimens from Java, and those from St. Helena, arc identical 

 with OUT numerous ones from South Africa. 



29. Ch. triatigula, Kze. ; " frond triangular thick coria- 

 ceous glabrous tripinnatc, pinna? and pinnules pctiolate re- 

 mote patent, secondary pinnules or lacinia; oblong obtuse 

 sinuato-lobate marginate the margin inflexed crenatc, involu- 

 cres marginal and as well as the sori at length diffuse conti- 

 guous, stipes and rachiscs flexuose rigid purple slightly hairy, 

 caudex short." Kmize, in Linncea^ x. p. 536. 



Hab. Caffraria and near the Cape, Ekhm. Rocky places in the Sneeuw- 

 bergen, Witbergen and Compasbcrg, Drege. Natal, Krauss, n. 385. — 

 " In habit resembling Ch. multifida, Sw., but differing in the triangular 

 fr<md, which is triplieato-pinnate and the pinna; not glandular beneath.'' 

 Yet Kunze describes his var. fi. fiexa of Ch. multfida as "fronde subtrian- 

 gulari (novella) subeglandulosa.'' — Diege, according to my herbarium, dis- 

 tributes two forms under this name, one marked {d) with young fructifica- 

 tion, which I consider identical with Ch. multifida, Sw. ; the other marked 

 (6) without fructification, and sufficiently agreeing with Kunze's descrip- 

 tion of the frond of Ch. triangula, differing from Ch. multifida in the " tri- 

 angular frond '' and in the larger pinnules. Krauss's solitary Port Natal 

 specimen in my herbarium, seems the same as this latter, but is less trian- 

 gular. It has the fructification of Ch. multifida, and seems almost to unite 

 tlie two. At any rate, we know other species of Cheilanthes to vary as much 

 or more than those we are now considering. 



30. Ch. Mathewsii, Kze. ; caudex stout creeping clothed 

 with black-brown shining scales, stipites 2 — 4 inches long 

 ebeneous glossy slightly downy above, fronds a span to nearly 

 a foot long coriaceous linear-lanceolate rather obtuse ta]ier- 

 ing much below in consequence of the contracted pinna) there, 

 glabrous above, the stiff rigid rachis glandidoso-pubesccnt, 

 pinnate scarcely bipinnate, pinnae subpetiolate approxi- 

 mate above very distant and gradually becoming very small 

 below deltoid more or less acuminate sometimes caudate, the 

 segments or pinnules linear-oblong deeply crenated with the 

 margin recurved so as to give almost a beaded appearance to 

 the pinnae, the teeth of the crenatures bear the squama^form 

 distinct but approximate involucres. Kze. in Schkuhr, Fil. 

 Siippl. p. 50, t. 25. Ch. pruinata, Kaulf. En. Fit. p. 210. 

 Ch. pruinosa, Kunze, in Linnaa, xxiii. p. 245. 



Hab. Peru, (Kaulfuss). Crevices of rocks and dry places, Huaman- 

 tanga, Matheivs, n. 605. Bolivia, Tiveedie, (smaller, pinnules shorter). — 

 Kunze's plate gives a very good general representation of this very distinct 

 Fern : except that the very beaded outline of the segments of the pinna) is 

 not shown. Many of our specimens are much more slender and many much 

 longer, but they do not, although very copiously in fructification, exhibit 

 such large, white involucres. — The texture is peculiarly firm and rigid, the
