of the central mountain, which is noticeable from Black Beach 
Road during the dry season when most of the other vegetation 
is leafless or has the leaves very much reduced, (nos. 1823- 
1824). Curpepper Isv.: F. X. Williams, collector. Croton 
bushes appear to be very abundant on the top of the island. 
GARDNER Ist. (near Hoop Ist.) : Snodgrass and Heller. Hoop 
Is_t.: common bushes (no. 1826). InpEFATIGABLE IsL.: 
Academy Bay, occasional bushes and small trees 10-15 ft. high 
to 300 ft. (nos. 1828-1829) ; northwest side, bushes 6-10 ft. 
high (no. 1827). James Ist.: James Bay, common bushes to 
1000 ft. (no. 1830). Srymour Isi., NortTH: Snodgrass and 
Heller. \WENMAN Ist.: slender trees and bushes (no. 1833). 
Endemic. 
Var. glabriusculus nov. var. 
Foliis ovatis denticulatis acutis utrinque sparsim pubescentibus; 
pilis aliis simplicibus aliis stellatis lamina circa 4 cm. longa 2.4 cm. lata. 
ABINGDON Ist.: small trees and bushes, 1000-1650 ft., (no. 
1834). A variety closely related to var. brevifolius, differing 
in the slightly denticulate margins of the leaves and in the 
presence of simple trichomes. Endemic. 
Var. grandifolius Muell. Arg. 1. c.; Rob. (1), 166.—ABINc- 
pon Ist.: bushes 6-10 ft. high, 1000-1650 ft., (no. 1835). 
ALBEMARLE Ist.: Villamil, bushes and small trees, abundant 
at 300-1300 ft., (no. 1836). It should be noted that C. Scou- 
leri extends up to 350 ft., so there is a slight overlapping of 
the two forms. CHARLES IsL.: common bushes, 1000-1350 ft., 
(no. 1837). Var. brevifolius extends up to 1100 ft. here, and 
the leaves increase considerably in size with the elevation, so 
that there is a close resemblance between var. grandifolius and 
the more mesophytic form of var. brevifolius. CHATHAM IsL.: 
Wreck Bay, low bushes in open country around 700 ft. (no. 
1838). James Ist.: James Bay, small trees and bushes 6-12 
ft. high above 1000 ft., very abundant in woodland around 
2000 ft., (nos. 1839-1840). It should be noted again that 
the lower limit of this variety, at this place, is also about the 
upper limit of var. brevifolius. Tower Is.: Snodgrass and 
Heller. Endemic. 
Var. Macraei Muell. Arg. 1. c.; Rob. (1), 166.—ALBEMARLE
