ANONACEZ OF BRITISH INDIA. 115 
between this and MM. reticulata, of which this must be a very close ally, are the smaller 
number of the nerves in the leaves of this and the ovoid shape of its rugose fruit. Im 
its leaves this plant somewhat resembles some of the species of Popowia. And, inasmuch 
as its inner petals are larger than the outer and are vaulted, it is related to Orophea, 
from which, however, its numerous Uvarioid stamens and unisexual habit exclude it.

7. Mirreppora Prainn, Aig in Jowrn. As. Soc. Bengal 61, pt. 2,88. A tree 30 
to 40 feet high ; young branches tawny-pubescent, speedily becoming glabrous and 
dark-coloured. Leaves membranous, elliptic-oblong, rather abruptly and shortly acumi- 
nate, the base cuneate and often slightly unequal-sided; upper surface glabrous except 
the depressed strigulose midrib; lower surface much reticulate, glabrous, but with a few 
scattered hairs on the midrib and 12 to 14 pairs of rather bold, oblique, curving 
nerves; length 6 to 9 in., breadth 2:25 to 3 in.; petiole ‘24 in., pubescent. Flowers 
bisexual, from the axis of the fallen leaves, solitary, 4 in. in diam.; pedicels about *5 
in. long, softly tomentose, minutely bracteolate at the base. Sepals broadly ovate, 
acute, concave, tomentose outside, glabrous inside. Outer petals much larger than the 
sepals, ovate-orbicular, sub-acute; tomentose outside, glabrous inside. nner petals longer 
but narrower than the outer; the limb trapezioid, densely tomentose, glabrous inside at 
the base; the claw narrow, about as long as the limb, tomentose on both surfaces, 
Stamens in the male flower numerous, short, cuneate; the apical process of the connective 
truncate, concealing the apices of the dorsal anthers. Pistils 0. Female flowers unknown. 
Ltipe carpels sub-globose, rather truncate at base and apex, rugulose, minutely pubescent, 
°65 in. in diam. Seeds about 5, plano-convex ; the testa membranous, rugulose,

The inner petals of this species are undoubtedly longer than the outer; but they are 
much narrower. Technically they are the petals of Orophea rather than of Miti ephora ; 
but Ate numerous Uvyarioid stamens and the unisexual habit are those of the latter, 
to which I accordingly refer it. I have been able to examine only a few flowers of the 
species, and these are all tetramerous; but whether this arrangement is normal or only 
occasional I am unable to say until larger suites of specimens shall be obtained.
