252 NOTE ON THE GENUS HENSLOWIA. 
nature and so delicate a texture, some allowance must doubtless be 
made for inaccuracies in pictorial representations taken from dried 
specimens. As a voucher for the correctness of the characters I have 
given above, I may state that they were taken from a number of living 
plants, carefully dug up whilst in bloom from their native locality, and 
potted; and that I have examined above 156 expanded flowers. I 
rely chiefly on the presence of only two fertile stamens, the synanthous 
ciliated leaves, and the glandular pubescence (not alluded to by either 
of the above-mentioned authors), as distinguishing the Chinese plant. 
It is a profuse flowerer, and the blossoms, which are about the size of 
a shilling, and open between eleven and noon, and close about four 
P.M., being produced for a considerable number of days in succession, 
it has certainly a claim to cultivation, especially if the white and lilac 
forms are intermixed. 
NOTE ON THE GENUS ZENSLOWIA, Blume. 
By H F. Hasor, Pu.D. 
Professor Blume, who established this genus in 1850, describes the 
flowers as “ abortu monoici" (Mus. Lugd. Bat. i. 242); whilst both 
Alph. De Candolle (Prodr. Syst. Veg. xiv. 630) and Miquel (Flora 
Ind. Batav. i. 1. 779, sub voce Dendrotrophe) employ the term * monce- 
cious’ simply. Mr. Bentham, describing the Hongkong H. frutescens 
rom Major Champion’s specimens (Hook. Journ. Bot. v. 194), calls 
it “abortu dioica”; and, in his * Flora Hongkongensis,’ mentions the 
male and female flowers as on separate plants. Whether Blume's 
description is accurate, as applied to the Archipelagic parasitical spe- 
cies, which Miquel (op. cit. p. 1006) says must be reduced in number, 
I cannot say; but, so far as the South Chinese terrestrial plant is con- 
cerned, the term ‘ diccious’ is, strictly speaking, inapplicable. There 
are two forms of the plant: a purely male one, in which the flowers 
are furnished with a thick fleshy disk, but with no ovarian cavity; and 
a perfect hermaphrodite one, with a fully organized gynccium, and 
stamens exactly as in the male flowers, the anthers copiously pollini- 
ferous. The term “ imperfectly polygamous” would therefore, perhaps, 
convey a more correct idea of the true state of things. Blume de- 
scribes and figures (op. laud. t. 43) the anthers in Z. varians as “ dorso
