Western 

 Australia. 



spreading, claws with strong woolly margins, outer surface of petal also 

 tomentose. Calyx wide campanulate, smooth, glabrous, gland-dotted, teeth 

 five, short, deltoid acute, 10-vemed, one to each sepal and one between. 

 Fruit and seed not seen. 



Habitat. An imperfectly known but undoubted wild species 

 found in Western Australia. 



Citation of Specimens. Only one seen by me, and that contributed by 

 the late Sir Ferdinand Baron von Mueller. It in many respects resembles 

 Thurberia or Cienfuegosia.

5. G. DARWINII, sp. nov. : G. PURPURASCENS, Hook. f., Linn., 

 Soc. Trans, xx., 1847, 231 ; G. KLOTZSCHIANUM, Eobinson and 

 Green, Contr. Gray Herb. No. 9, 145 ; G. BARBADENSE, 

 Eobinson, Fl. Galdp. Isl. (in part) Am. Ac. Arts, Contr. from 

 Gray Herb. No. 24, 173. 



Leaves softly and minutely stellately tomentose, especially below, 

 deeply 3-foliate, scarcely cordate, gland obscure on middle vein ; 

 bracteoles ovate cordate, teeth suddenly acuminate, awl-shaped, and 

 hooked (see Plate No. 4). 



This appears to be a perennial shrub. Branches strongly angled, dark 

 purple, above minutely woolly. Leaves 3| x 2 inches, softly tomentose 

 when young, less so with age, prominently gland-dotted (the glands often 

 large and surrounded with a coloured ring within the tissue), central lobe 

 much the longest, linear oblong acuminate, with the sinuses on either side 

 thrown up in folds, veins prominently woolly, petioles 1 to 1^ inches long, 

 thickened upwards, slightly woolly near the apex and sparsely warted 

 below. Inflorescence axillary, flowers solitary, on short rigid pedicles ; 

 bracteoles quite free, not possessed of extra-floral glands (nectaries), ovate 

 cordate, cut into many very narrow awl-shaped teeth that become almost 

 hooked, at first softly tomentose then accrescent and glabrescent, mem- 

 branous, prominently reticulated, completely enclosing the fruit. Flowers 

 very large, wide spreading, yellow, with purple hairy claws to the petals ; 

 calyx undulate or cut square across (f. 2). Bipe fruit and seed not seen by 

 me, but the pollen-grains are distinctive (see Plate No. 53, f. 3). 



Habitat. James and Chatham Islands, Galapagos. 



Citation of Specimens. In the Cambridge University Herbarium there 

 is preserved the sample of Gossypium collected in 1835 by Mr. Charles 

 Darwin, during the voyage of the ' Beagle,' at James Island, Galapagos. 

 This was named G. purpiirascens, Poir., but, I venture to think, incorrectly. 

 It is a perfectly good new species which has since been twice re-collected 

 at the Galapagos. In Kew there are two sheets of this interesting plant 

 collected by Dr. Habel during the expedition of the ' Indefatigable ' in 

 1868 ; the other collected by Dr. G. Bauer (n. 22) in the south-west end of 

 Chatham Island, during June 1 891 (ex Herb. A. Gray).
