Vor. I] STEWART—BOTANY OF THE GALAPAGOS ISLANDS FLA 
decumbent bushes around dried pools in the interior of the 
island (no. 1610). CHarves IsL.: common bushes, forming 
open thickets near the shore, and trees around 650 ft., (nos. 
1611-1613). CHatHam Ist.: Wreck Bay, occasional low 
spreading trees in sandy soil near the shore (no. 1614). Dun- 
cAN Isx.: occasional near the shore; at 1000 ft. it is very 
abundant as prostrate and decumbent bushes, often covering 
considerable areas on the floor of the crater; occasional at 
1275 ft. The prostrate habit on the upper parts is probably 
due to the wind, (no. 1668). GARDNER IsL. (near Hoop 
Ist.) :. common bushes (no. 1670). Hoop Ist.: common 
bushes all over the island (nos. 1671-1673). INDEFATIGABLE 
Ist.: southeast side, common bushes to 600 ft. (nos. 1674- 
1675) ; northeast side, small stunted trees near the shore (no. 
1676). James Ist.: James Bay, Snodgrass and Heller.

The series of specimens from this island show well the 
marked foliar differences which occur between individuals from 
the dry and moist regions on practically all of the islands 
where this species is found at low and high levels. The speci- 
mens from the dry region have the leaflets villous on both sur- 
faces, margins strongly reflexed, resin dots numerous and dark 
brown in color, venation prominent on the under surface ; size 
of leaflets, 5.5 by 7 mm. Specimens from above 1000 ft. have 
the upper surface of the leaflets atomiferous, the lower softly 
pubescent, margins but slightly reflexed, resin dots few and 
amber colored, venation not prominent ; size of leaflet, 31 by 43 
mm. Specimens from 600 and 700 ft. show characters which 
closely correspond with the specimen from 1000 ft. except that 
the leaflets are smaller, (nos. 1679-1682). ALBEMARLE ISsL.: 
Elizabeth Bay, Snodgrass and Heller; Iguana Cove, common 
in the vicinity of the cove; Tagus Cove, abundant in open 
areas in tufaceous soil all over the lower parts (no. 1683).
