Mr. Bennett, not being aware of our prior name, gave
it the one quoted above, accompanied by a full description
and some remarks on its affinities. The two
generic names merit a passing notice. Microelus—
a little nail—is in allusion to the rudimentary style of
the male flower, the top of which is flattened like the
head of a nail. Stylodiscus evidently alludes to the
same structure, the dilated disk-like head of the male
style.
1881. D alechampsia veeutina (It. W.), leaves
deeply 3-lobed, cordate at the base, serrated, sub-
glabrous above, venoso-reticulate whitish and velvety
beneath, calyx of the female flower persistent, six-
lobed, lobes very hairy, dentate on the margin: hairs
rigid bristle-like.
Neilgherries ? I am not quite sure in regard to
the station. I t appears a very distinct species, allied,
however, to a Cape species of which I have a specimen
under the name of “ D. Capensis, Spreng.”
1882. D alechampsia Indica (It. W.), leaves 3-
foliolate, lateral leaflets gibbous, sometimes lobed externally,
all serrated, cuspidato-acuminate, shortly and
sparingly pubescent on both sides: female, calyx persistent,
8-lobed in the lateral flowers; lO'-lobed in the
middle one, lobes serrato-dentate.
Dindigul Hills. These are both rare plants, and, so
far as I have seen, the only species of the genus
natives of India. Lamark describes another, which
he saw in Jussieu’s Herbarium, said to have been
found in India, but which seems never to have been
met with since, and therefore doubtful as regards this
being its native country. The rest of the genus, with
very few exceptions, is of South American origin.
The genus is a very marked one, being at once distinguished
by its two large 3-lobed pale yellow bracts
enclosing both the male and female flowers. These,
on being reflexed, bring into view a sessile capitulum
of male flowers seated in a cup-shaped involucre and
3 females, embraced by two somewhat similar but
smaller undivided bracts, each furnished with from 6
to 10 linear dentate sepals beset with stiff bristly
hairs and tenninating in a long stout style and club-
shaped, truncated stigma. As the seed advance -to
maturity the pedicels elongate, the sepals enlarge
and become riged, and surround the 3-celled capsule,
much as the involucre of Pavonia does its capsule.
1883. Macaranga Indica (R. W.), dioecious,
arboreous : leaves stipuled, peltate: stipules paired,
broad ovate, cuspidate: male flowers panicled, glomerate':
glomerules bracteate: bracts petioled, glaudu-
lose: calyx 3-par ted, pubescent: stamens 6-8, mona-
delphous at the base: anthers flattened, tetradymous:
entire or slightly dentate, pubescent and punctuate
beneath, glabrous above, female panicles axillary:
flowers solitary or paired, pedicelled, bracteate:
bracts sometimes pedicelled and glanduliferous as in
the male: calyx 4-parted: capsule covei’ed with resinous
points.
Neilgherries, Courtallum, flowering during the
autumnal months. The margin on the leaf is too
distinctly dentate, at least for the average outline of
leaves.
When preparing the le tter press character, for the
subject of this plate (which I have purposely made
very full), I was led to examine more carefully than
I had hitherto done all the specimens in m y herbarium
corresponding in their general aspect with the
one under consideration, and at the same time to
compare the distinctive characters, which I did not
previously quite understand, of Mappa and Macaranga,
which I was prevented doing when naming the drawing
preparatory to sending it to the Lithographer.
The distinction I now find is confined to a single
point of the structure of the female flower, and that
without it, the two genera are undistinguishable. In
Mappa the female flower has 2 or 3 styles, and the
ovary as many cells : in Macaranga it has one style
and a one-celled ovary. This solitary distinction is
however strengthened by geographical distribution,
Mappa being confined, so far as yet known, to the
Eastern Archipelago while the Asiatic division of
Macaranga seems equally limited to the Indian
Peninsula. Blume, for example, enumerates 5 species
of Mappa from Java, while I can produce four
(including Roxburgh’s Osyrispeltata, No. 817, of this
work) of Macaranga from the Peninsula. As regards
foliage, it may be stated that, judging from
Blume’s characters, the leaves of Mappa have a
greater tendency to elongation and to assume an
ovate outline than those of Macaranga, all of which
are orbicular at the base with a rather abrupt acumi-
nation at the apex. That shown in the plate, with
the exception of the dentation which is too marked,
may be taken as the outline of all the rest; which
may be thus briefly distinguished.
1. M. Indica, flowers 6-8-androus, bracts glandu-
lose. Neilgherries.
2. M. tomentosa, flowers 2-3-androus, bracts folia-
ceous, obovate, cuniate, tomentose. Malabar.
3. M. Roxburghii, flowers triandrous, bracts ovate,
acute, serrated. Circars.
4. M. fiexuosa, flowers 3-5-androus, bracts at the
forks of the panicles foliaceous, coarsely serrate, at
the glomerules glanduliferous. Courtallum.
Of all these it is my intention by and Ijye to give,
in a single plate, analytical figures so as to* show their
differences by contrast.
Blume’s genus Pachystemon, as regards the male
plant, has so much the habit of this genus that I at
first supposed it a monandrous species of one of the
two genera.
I t however differs not merely in the reduced number,
but also in the structure of the stamen, which
is tridymous, that is, has a 3- in place of a 4-celled
anther, like all the preceding. Like them the number
of stamens differ, 1 being the usual number, but
two are sometimes present.
1884. Claoxyeon digynum (R. W.), dioecious:
leaves alternate, ovate lanceolate, acuminate, serrulate,
glabrous: male flowers glomerate, spicate: spikes
axillary, slender, about the length of the leaves: calyx
3-parted : stamens numerous: females spikes equaling
the leaves: flowers sessile: calyx 4-Iobed: ovary
2-celled, with two long subulate styles: capsule 2-
coccous: cocci sub-globose, pubescent.
Ceylon. I know nothing of this plant beyond what
I learn from the specimens, which I gathered many
years ago in Ceylon. They are unaccompanied by
any notes, or memorandum of the plant, or where
they were obtained.
1885. B AEIOSPERMCM POLYANDRUM (R. W., Croton
polyandrum, Roxb.), leaves oval, often lobed,
toothed, or coarsely and remotely serrated: spikes
