correspond so well with mine that I could not ven- 

 ture to view the 2 plants as distinct species- Figures 

 8 and 9 of the plate show the two kinds of flowers, 

 as seen after the removal of the involucre. 



1864. 



(Si 



Roth.), leaves oblong lanceolate, tapering towards the 



base, glabrous : whorl 3-5-branched with occasionally 



several axillary branches below: branches 2 or, in 



old plants, 3 times dichotomous, with broad cordate 



sub-perfoliate bracts at each fork : flowers solitary liferous at the apex 



in the fork : ends of the glands of the involucre pro- 



^. ^ ^ ^ ^ ^ ^ 



The figures 1, 2, 3, in the plate, are taken from young 

 flowers not perfectly opened. Fig 7, exhibits one of 

 those rare cases showmg a tendency to a return to 

 monoecious habit by the production of a female flower 

 at the base of the spike. The character of the tree, 

 if monoecious, is to have the female flowers on sepa- 

 rate branches. 



1866. Falconera Malabarica (R. W.), stamens 

 somewhat exserted: ovary 3-cclled; petiols glandu- 



longcd, tooth-like : mvolucre ciliate on tne margm : 

 stamens furnished at the base with a filiform pube- 

 scent scale, seed glabrous. 



A very common alpine plant, found on nearly all 

 the higher hills that I have visited- I have speci- 

 mens from Mahablishwar, and Ceylon, and from 

 numerous mtermediate stations. It seems curious 

 that a plant so extensively distributed should be so 

 imperfectly known. I cannot find any description 

 that accords with this plant, and adopt the present 

 name because I feel sure that I can quote an autho- 

 rity for it, but not a satisfactory one, in as much as 

 Roth describes a rather rare variety; but on the 

 other hand, Mr. Bentham has, in Wallich's list, ranged 

 Heyne's -B. Icetuy and my E. segetalis (this plant) under 

 the same number, as being identical, I do not how- 

 ever expect that when the genus has been thoroughly 

 revised that the name here given can be retained. 

 Roxburgh's E, glauca seems to be this plant, but 

 I suspect not Willdenow's, which is from New Zea- 

 land. In characterizing this species, I have avoided 

 the term umbel, as applied to the terminal whorl of 

 floriferous branches, on the supposition that it is erro- 

 neous, as shown by the often many similar lateral 

 branches which spring from the axils of the leaves 

 below. 



1865. Exc^cARiA cEENuiATA (R. W,), arborc- 

 ons, dioecious or rarely monoecious, leaves opposite, 

 oblong, lanceolate, crenulat^, acuminate, coriaceous, 

 glabrous : male spikes axillary or from the ends of 

 the branchlets, solitary : anterior bract entire, coria- 

 ceous on the margin, the small lateral ones and sepals what coriaceous, and uT drying become of a pale 

 membranous, fimbriato-serratcd : female spikes axil- greenish-yellow colour. In the plate I find I have 

 lary, 2-3-flowered : bracts and sepals as in the male, erroneously quoted Roxb., in place of WiDdenow, as 



Malabar, and Western slopes of the Neilgherries. 



We are indebted to Dr. Royle for the genus Fah 

 conera^ founded on two Nepaul trees. The peninsu- 

 lar species differs from both his in its S-carpellary 

 3-cellcd ovaries, his having only two ; in all other 

 respects my plant perfectly agi-ees with his, and ap- 

 proaches so near P, Wallichia^m^ of which I have a 

 male specimen, that I should probably have referred 

 it to that species but for its 3-cclled ovaries, and the 

 petiols being glanduliferous at the apex, in place of 

 the base. 



Dr. Royle refers the genus to the order Antidismece^ 

 which somewhat surprises me, as it is evidently Eu- 

 phorbiaceous, and indeed so near Sapium that I think 

 it might have been admitted into that genus without 

 much straining, and I almost suspect wiU yet be re- 

 ferred to it- The habit is adverse, and its very de- 

 cided dioecious character may probably keep the 

 two genera distinct, but scarcely the floral structure. 

 In support of this view, I shall introduce into my 

 next pait illustrations of the genus Sapium. 



1867. Geloniijm xanceoijitum (Willd.), leaves 

 lanceolar, entire : flowers crowded but distinct : sta- 

 mens numerous : capsules tricoccous. 



Balaghaut Mountains, near Madi'as. 



Roxburgh, who describes this plant from Bengal 

 specimens, does not seem to have met with it to the 

 Southward- WUldenow, however, the authority for 

 the species, received his specimens from Dr. Klein, 

 whose researches did not extend much beyond Madras. 

 The leaves are perfectly glabrous, quite entire, some- 



A rather common small tree in alpine jungles. I 

 have gathered it in many localities, but have rarely 

 met with it exceeding a foot or 18 inches in circum- 

 ference but tall in proportion ; from 20 to 30 or even 

 40 feet in height. The whole plant is very milky and 

 the milk very acrid* On one occasion, when cutting 

 down a tree, I saw uistantaneous and intense oph- 

 thalmia produced by a particle of the milk acciden- 

 tally falling on the eye» 



It seems curious that this tree should remain still 

 undescribed, for I have often met with it. 



In its relations it stands next to Griffith's E. oppo- 

 sitifolidf and is so near, that it seems difficult to define 

 their limits, though certainly distinct. Griffith in his 

 remarks on E. oppositi/olia observes that " although 

 it presents differences, especially in habit, from 

 Exccecaria^ I have considered it best to refer it to 

 that genus." To show the soundness of this con- 

 clusion I have given analyses (Fig. B- in the plate) 

 of E, Agallorha^ the type of the genus, which wiU 



the authority for the species. 



1868. Ade£ia neriefoua ( Roxb. ), shrubby ; 



leaves alternate, linear lanceolate : spikes axillary, 



solitary. 



In low moist soil on the banks of streams and ca- 

 nals, not uncommon. I have often met with it in the 



Camatic. In the Coimbatore district it is frequent in 



such localities. 



1869. AnELiA EETusA (J. Graham), a low shrub, 

 leaves alternate, sessile, obovate cuniate, retuse, 

 slightly crenate : flowers axillary two or three together, 

 stamens very numerous. 



Banks of the Cavery about Errode, frequent, Deccan 

 generally, Gibson ; Circars, Walter Elliot, Esq. 



The drawing is taken from specimens gathered on 

 the banks of the Cavery, most likely the produce of 

 seed carried down by the stream from the Deccan. 

 I have not got the female plant.
