Mi\ Bennett, not being aware of our prior name, gave 

 it the one quoted above, accompanied by a full descrip- 

 tion 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. Dalechampsia velutina (R. AV.), leaves 

 deeply 3-lobed, cordate at the base, serrated, sub- 

 glabrous above, veuoso-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. It appears a very distinct species, allied, 

 however, to a Cape species of which I have a spe- 

 cimen imder the name of " D. Capensis^ Spreng." 



1882. Dalechampsia I:NmcA (R. W,), leaves 3- 

 foliolate, lateral leaflets gibbous, sometimes lobed ex- 

 ternally, all serrated, cuspidato-acuminate, shortly and 

 sparingly pubescent on both sides : female, calyx per- 

 sistent, 8 -lobed in the lateral flowers ; 10-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 Herbariuni, said to have been, 

 found in India, but which seems never to have been 



one mider consideration, and at the same time to 

 compare the distinctive characters, which I did not 

 previously quite understand, of Mappa smd Macaranga^ 



which I was prevented doing when naming the draw- 

 ing 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 ai-e 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 spe- 

 cies of Mappa from Java, while I can produce four 

 (including Roxburgh's Osyris peltata^lS o.8\7^ of this 

 work) of Macaraiiga from the Peninsula. As re- 

 gards 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- 



met with since, and therefore doubtful as regards this ^^^iis, obovate, cuniate, tomentose. Malabar. 



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 dis- 

 tinguished 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 fm-nished with from 6 

 to 10 linear dentate sepals beset with stiff bristly 

 hairs and terminating 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, glome- 

 rate : glomerules bracteate : bracts petioled, glaiidu- 

 lose : calyx 3-parted, 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 pau-ed, pedicellcd, bracteate : 

 bracts sometimes pedicelled and glanduliferous as in 

 the male : calyx 4-pai'ted : capsule covered with resi- 

 nous 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. 



3. M, Roxhurghii^ flowers triandrous, bracts ovate, 

 acute, serrated. Circars. 



4. M. fiexiiosa^ 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 bye to give, 



differences 



figm- 



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. 



It however differs not merely in the reduced num- 

 ber, 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 num- 

 ber of stamens differ, 1 being the usual number, but 

 two are sometimes present. 



1884. Claoxylon bigtwum (R. W.), dioecious: 



leaves alternate, ovate lanceolate, acuminate, semilate, 

 glabrous: male flowers glomerate, spicater spikes 

 axillary, slender, about the length of the leaves : calyx 

 3-parted : stamens numerous : females spikes equal- 

 ing the leaves : flowers sessile : calyx 4-lobed : 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 



When preparing the letter press character, for the they were obtained, 

 subject of this plate (which I have purposely made 



very full), I was led to examine more carefully than 1885. Bauospermcm poxtandbum (R. W., Cro- 



I had hitherto done all the specimens in my herba- ton polyandmm^ Roxb.), leaves oval, often lobed, 



rium corresponding in their general aspect with the toothed, or coarsely and remotely serrated : spikes
