Hah. California, especially about San Francisco, Chamisso, Sinclair, Coulter, 

 Brackenridge, Hartweg, n. 2041, Bridges, n. 29G, as far south as the 35th parallel 

 of lat., Dr. J. M. Bigelow ,• Oregon territory, Mount Hood, Douglas, Nuttall. Hot 

 valleys of Ecuador, Seemann, n. 946. — A very distinct and well-marked species, 

 occupying a great extent of country on the Pacific coast from Ecuador in South 

 America to Oregon, which seems to be its limit in North America. It is remark- 

 ably uniform in its form and ramification. 



45. G. (Ceropteris) sulphurea, Desv. ; caudex very short 

 erect, stipites tufted purple-black when young pulverulent 4 

 inches to a span long, fronds membranaceous bright green 

 and glabrous white- or sulphur-pulverulent beneath ovate or 

 ovato-lanceolate bi- tri- or at the base subquadripiimate, 

 pinnae and inferior pinnules ovato-lanceolate the rest lanceo- 

 late the ultimate ones deeply pinnatifid, the segments oblong 

 or cuneate 5-6-toothed (in some cases deeply cut into very 

 narrow linear almost capdlary segments), veins dichotomous. 

 sori linear subconfluent, the capsules few and lax. — Acrosti-

Hah. West Indies : Jamaica, abundant. Cuba, C. Wright, n. 975, large form. 

 Venezuela, Linden. Tovar, Fendler, n. 357, At Antilly Gap, Jamaica, alt. 2500 

 feet, St. David's; same locality as Aspidium (Polystichum) iridens. Mr. Wil- 

 son finds a pretty variety 3-4 inches to a span long scarcely 2 inches wide, very 

 compact, white or sulphur-coloured beneath. — Myself as well as others have con- 

 sidered the G. pulchella of our gardens a distinct plant from the G. sulphurea, hut 

 my copious specimens from the West Indies and Venezuela satisfy me that they are 

 one, varying a good deal in composition and in the breadth of the ultimate divisions 

 of the pinnules ; in specimens from Venezuela as finely cut as in many Trichomanes. 



46. G. (Ceropteris) conspersa, Kze. ; caudex very small 

 erect possibly annual, stipites very slender filiform flexuose 

 .3-4 inches to a span long purple-ebeneous, fronds 3-4 inches 

 to 1 foot high very thin membranaceous subtriangulari-ovate 

 acuminate glabrous above, sparsely white-farinaceous beneath, 

 (sometimes of firmer texture and yellow-farinaceous) tri- or 

 rarely below quadripinnate, ultimate pinnules \h line to \ of 

 an inch long trapezoid cuneate sessile subdichotomously or 

 digitately pinnatifid, ultimate segments cuneate or linear en- 

 tire obtuse, veins forked soriferous, sori linear more or less 

 elongated and more or less confluent. — Kze. in Linnaa, xviii.
