from the females. The male inflorescence is a more or less we 
branched axillary panicle or compound catkin, from 2}-1 
long, with weak, thread-like, hairy ae s and pedicels. The 
male flowers are numerous, 3-5 mm. in diameter, and consist of a 
simple, very thin perianth, divided neatly to the base into four to 
ine narrow equal segments, and an equal number of stamens 
alternating with the segments. In steams and appearance they 
e almost exactly like those of the common oak. The female 
inflorescence is similar in structure to that of the sweet chestnut, 
consisting of an almost closed, usually five-toothed eee. borne 
én a flattened pedicel and containing three or four collateral 
ec of which the two outside ones are, perhaps, aivatl 
aborti 
ie the flowering stage, the female inflorescences including the 
narrow flattened pedicel and the exserted styles, are abou 
long, and, as are seated the a of the crowded 
leaves and of the same colour, they are easily ove ed 
the base of the cell. Ata little later stage, in consequence of un- 
equal growth, it is horizontally oblong, nearly as large as the 
tweloh seed, that is, 6-8 mm. long, and almost symmetrically 
developed appendage, which breaks as and is absorbed during the 
development of the ovule into seed. A similar growth and trans- 
formation is unknown to ‘un in any other natural order 
The ovule of Orthopterygium is very imperfectly known, but the 
attachment appears to be lateral and the funicular appendage cup- 
shaped at the basal end, bilamellate upwards, and more or less 
enclosing the embryoniferous lobe. Mr. Boodle, who has fully 
examined the ovule of Jubiania from microtome sections, describes 
it as swepemen ogre a a single integument. 
und f of Juliania are samaroid in form, the 
wing bite ce aaa saaisel, at the base of which it disarticn- 
lates from the undifferentiated part of the pedicel. They vary 
4-7 cm. in length by 14-24 cm. in width. Externally they 
strongly resemble the samaroid pods of certain genera of Leguminosae, 
po: are of Platypodium and Myroxylon. The involucre itself, 
of the largest fruits seen, is only about 1 em. deep by 2 cm. wide. 
It is ealipined of very hard tissues and is quite Sebichisoent: Only 
quite young fruit of Orthopterygium is known. In this the flattened
