surrounds an indefinite number of sessile carpels, arranged like the 

 stamens, and each consisting of an ovary surmounted by a thick 

 conical style covered with large stigmatic papillse. The ovary contains, 

 suspended on its inner angle, a single descending anatropous ovule, 

 with its micropyle upwards and inwards. The perianth persists 

 around the base of the multiple fruit, which consists of a variable 

 number of shortly-stalked drupes analogous to those of Peumiis and 

 H. ortonia. Each contains a suspended seed, whose seed-coats enclose 

 a fleshy albumen, surrounding an inverted embryo with a long cylin- 

 drical radicle and oval membranous cotyledons/ This genus consists of 

 trees with opposite leaves, and dioecious flowers in simple racemes, 

 in bunches of cymes, or in axillary cymes. Five species are known, 

 inhabitants of Australia" and the neighbouring regions. One, 

 H. arbor ea,^ comes from New Zealand, and another, H. dorstenioides* 

 from the Feejee Islands, remarkable for a long, dilated, truncate 

 prolongation of the connective, recalling the arrangement seen in 

 the genera of Anonacece with " stamens of the VvariecB!' This form 

 of anther is also met with in difierent degrees in the two species 

 from New Caledonia,' in which the receptacle is like a very wide 

 cup with its rim much everted, and the calycinal pieces become 

 shorter and more obtuse, while all that is left to mark the perianth 

 in the female flower is a free circular border, entire, or scarcely 

 crenulate or sinuous. 



In Mollmedid (figs. 328-336) the drupes are also naked, but only 



' The direction of the embryo is, as in Kor- 

 tonia, oblique to the axis of the albumen. In a 

 large fruited species from New Caledonia, a large 

 brownish cup-shaped chalaza is observed, applied 

 over the whole base of the albumen.

 closely recalls Palmeria by the form of the re- 

 ceptacle aid perianth of the male Hower. In 

 the male flowers of H. Baitduuini especially we 

 see a thick-rimmed cup with a short perianth, 

 and this is even reduced to an obtuse swelling in 

 the female flowers ; and if the cup supporting 

 the carpels is of axial nature, we may say that a 

 tendency towards the suppression of the true 

 perianth exists here ; and the structure of these 

 flowers also approaches that of Eiipomatia and 

 the peculiar Magnoliacea of the genus Trocho- 

 dendron.
