MALVACEAE 

 Abutilon Gaertn. 



A. depauperatum (Hook, f.) Anderss. (1), 230, (2), 98. 

 Sida depauperata Hook. f. (3), 232. A. Anderssonianum 

 Garcke in Anderss. (1), 230, (2), 98, t. 15, f. 1; Rob. (1), 

 173. — Abingdon Isl. : occasional low bushes around 650 ft. 

 (no. 1960). Albemarle Isl.: Iguana Cove, Snodgrass and 

 Heller. The sterile specimen collected at this place by Snod- 

 grass and Heller and called Sida cordifolia by Robinson 1. c. 

 no doubt belongs to this species; Tagus Cove, low bushes 

 around the base of the mountain at 200 ft. ; Villamil, common 

 bushes below 500 ft. (no. 1961). Barrington Isl.: Snod- 

 grass and Heller. Bindloe Isl. : Snodgrass and Heller. 

 Charles Isl. : bushes 2-3 ft. high around 450 ft. (no. 1962). 

 Chatham Isl. : Wreck Bay, bushes 2-3 ft. high in shady 

 places around 300 ft. (nos. 1963-1964). Duncan Isl. : occa- 

 sional low shrubs at 1300 ft. (no. 1965). Gardner Isl. (near 

 Hood Isl. ) : Snodgrass and Heller. Hood Isl. : common 

 bushes in the interior of the island (no. 1966). Indefatiga- 

 ble Isl. : north side, Snodgrass and Heller. Tower Isl. : 

 occasional bushes (no. 1967). The principal differences be- 

 tween this species and A. Anderssonianum, as given by Garcke 

 1. c, are the number of carpels, the number of seeds in each, 

 and the shape of the lobes of the calyx. One specimen in the 

 collection has seven carpels, which is intermediate in number 

 between the two species, and there is considerable variation in 

 the shape of the calyx lobes throughout. The fact that A. 

 depauperatum has 3-5 seeds in a carpel, and A. Anderssonian- 

 um always 3, is hardly sufficient ground for the formation of 

 two distinct species. It is likely that the specimens described 

 as A. Anderssonianum are more mesophytic than the typical 

 A. depauperatum. Endemic.
