the edges recurved. E.tetraptera seems to have the most 
coriaceous leaves hitherto recorded, but some of these 
leaves are quite as thick. 
This form has been found in the Hornsby-Berowra Creek 
{fresh water) district, thence to Willoughby and Middle 
Harbour (Port Jackson), and, going south of Port Jackson, 
at Heathcote and Waterfall. Iam especially indebted to 
Mr. W. F. Blakely for notes and a perfect series of speci- 
mens from the Hornsby district. 
The relations of (a) and (b) have not yet been. fully 
worked out. They may be identical, and perhaps may be 
accepted as a type of the somewhat unsatisfactorily 
described E. capitellata Sm. 
c. The Outer Domain, Sydney. See fig. 4a, plate 38. It 
will be seen that the juvenile leaves of this form are lan- 
ceolate with an almost absence of stellate hairs. Inshape 
and in vestiture No. ec differs from No. a. Specimens from 
Sutherland (J. L. Boorman, 16th October, 1918) in no way 
differ from those from the Outer Domain. The precise 
range of this form, which is a large tree, has not been 
worked out, because of the difficulty of getting juvenile 
foliage, or of raising seedlings. 
(It is easy to omit some seedlings when one has to deal 
with a genus of over 200 species, and where, in some 
species, it has been found necessary to grow scores of 
Seedlings, examining and depicting them in different stages 
over a series of years). 
d. The Blue Mountains form (Blackheath, etc.). See 
pages 216 and 217, part viii, C.R., also fig. 3a, plate 38. 
This is a large tree, and if we compare these specimens 
with Cox’s River (Cambage and Maiden), also a large tree, 
we find juvenile leaves broadly-ovate to broad-lanceolate, 
shortly and distinctly petiolate, and that the Blue Moun-
