16 FLORA VITIENSIS. 
latis dentatis basi cuneatis, subtus candicantibus; pedunculis axillaribus distincte articulatis 1-floris 
folio brevioribus ; carpellis 8-10 birostratis.—Cav. Diss. vol. i. t. 3. fig. 12.—Common on roadsides: 
` and in waste places all over the group (Seemann! n. 16; Milne! U. S. Expl. Exped.). Also col- 
lected in the Sandwich Islands (Barclay !), New Caledonia (Herb. Webb.), Eromanga (M‘Gillivray !), 
Salomon group (Milne!), Tana (Capt. Cook !), and Samoan Islands (Sir E. Home !). 
All the above-quoted specimens have carpels with two long awns, and have the true look of S. rhom- 
bifolia, as I have seen it in many parts of tropical America; and I am inclined to attach a greater value to 
the presence or absence of the awns than several other writers are prepared to do. An awnless species 
from Tahiti, gathered by Barclay, I am not able to refer to any of the forms of S. rhombifolia, though it is 
closely allied to this species, and I find it identical with a plant alluded to but left undetermined by Ben- 
tham (Hook. Journ. of Botany, vol. iv. (1842) p. 122).
