lanceolate, subdistant ; powder yellow, thin ; st. and raehis pubescent.
Hab. Tropical America.—There is no clear line of distinction between this and the
preceding. The forms associated here differ mainly from those placed under calomelams
by being firmer in texture and leas divided. G. guianensis, Klotzsch, comes between
a and y, aud Q. adiantoides, Karst., is said to differ from ? by its sublaneeolate outline
aud acuminate pinnules. We cannot distinguish from G. ochraeea a plant gathered by
Gerrard in Natal.
64. G. (Cerop.) calomelams, Kaulf. ; st. tufted, firm, 6-12 in. 1., nearly black ;
f r . 1-3 ft. 1., 6-12 in. br., oblong-deltoid, tripinnatifid ; p innæ close, lanceolate,
the lowest the largest, sometimes 6 in. 1., 1 j-2 in. br. ; lower pinnl. distinct,
lanceolate or subdeitoid, often cut down nearly to the rachis ; texture subcoriaceous
or herbaceous ; powder white.—Hh. G. F. t. 80.—/3, G. peruviana,
Desv. ; f r . smaller ; st. and rachis castaneous ; lower p in noe deltoid ; lower
pinnl. often cut down to the rachis.—y, G. clirysophylla, Kaulf. ; size and habit
of (3, but the rachis darker and the powder bright yellow.—Hh. iSp. 5. p . 148.
Hab, West Indies, southward to Rio Janeiro, Peru, and Samoa ; Tropical West
African Islands.—We include here a wide range of forms connected by very gradual
intermediate stages. Q. FEerminieri, Martensii, and Massoni of Link, and C. intermedia,
Pee, are all intermediate between a and y .
55. G . (Cerop.) ffc h e lla , Linden ; st. tufted, firm, 6-9 in. 1., da rk chesnut-
brown, powdery ; f r , 6-12 in. L, 4-6 in. br., oblong-deltoid, tripinnatifid ; lower
the largest, lanceolate-deltoid ; p in n l. imbricated, tlie lower ones subdeitoid
; segm. flabellato-cuneate, often j in. br. ; texture herbaceous ; powder
pure white.—77/. F il. E x . t. 74.
Hab. Venezuela.—Joined in “ Sp. Fil,” to 0. sulphwrea, from which it differs by its
more robust habit, white powder, and frond broadest at the base. I t comes very near
Q. peruviana. Var. WettenhaUiana, Moore, is a garden variety, with pale sulphur-
coloured powder.
56. G. (Cerop.) sulphurea, Desv. ; st. densely tufted, 1-6 in. 1., generally
short, slender, chesnut-brown, often powdery ; f r . 6-12 in. 1., 8-4 in. br., ovate-
lanceolate, trip in n a tifid ; pinnoe lanceolate, the lower ones gradually reduced ;
p in n l. flabellately cut, with entire or cleft cuneate segm. 1 - l j lin. br. ; texture
herbaceous ; powder bright yellow.—Hh. Sp. 5. p , 147.
Hab. West Indies.—Distinguished by its cutting, small size, herbaceous texture and
frond narrowed in the lower third.
57. G. (Cerop.) rosea, Desv. ; st. tufted, slender, 3-6 in. 1., da rk chesnut-
brown, glossy ; f r . 6-12 in. 1., subdeitoid, quadripinnatifid ; p in noe not numerous,
often distant, deltoid, the lower ones 3-4 in. 1., 2 in. br. ; pinnl. and segm.
deltoid, the u lt. divisions small, flabellato-cuneate ; texture herbaceous ; powder
white or tinged with r e d ; pale-brown. — G. conspersa, Kze. Hh. Sp. 5.
p . 147. G. farinosa, Bojer.
Hab. Mascaren Isles and Natal.—Q. conversa, Kze,, appears to be a slender flaccid
form of the Mascaren species. A plant from Bourbon, received from the Paris Museum
under the name of G. aurea, is more robust in habit, with broader and closer divisions
aud yellow powder, and Dr. Welwitzsch has gathered similar examples in Angola.
