i6 FLORA VITIENSIS. 
latis dentatis basi cuneatis, subtus candicantibus; pedunculis axillaribus distincte articulatis 1-floris 
folio brevioribus ; carpellis 8-10 birostratis——Cay. Diss. vol. i. t. 3. fig. 12.—Common on roadsides 
and in waste places all over the group (Seemann! n. 16; Milne! U. 8. 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 8. 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).
