_ There must exist some confusion in A, Gray’s herbarium, or else that excellent botanist could not 
refer my u. 268, which is certainly identical with the authentic specimen of Forster’s Buphthalium helian- 
thoides, and heneo with WF. striqulosa, DO., to W. Forsteriana (Buphthalmum wniflorum, Forst. Prody. 
ne D41; MWeddelia Forsteriana, Endl. Fl, Norf. p. 51), of which authentic specimens exist at the British 
Museum. | Of HW. Forsteriana I have not seen any specimens from Viti, but as it is a common seabeach 
plant in Norfolk Island (Forster !), the Isle of Pines (Sir E, Home !), and New Caledonia (M‘Giliiyray !), 
if may be expected to occur there, WW. strigulosa is evidently a rather variable plant,
