' 310 CHARACTERS OF NEW SPECIES 
Folia fere O. aspere at flores majores et 
calycis lacinie elongate, non ut in illa ob- 
longz et tubo multo breviores. 
I have not as yet seen any species that 
seems to agree with O. octandra of De 
Candolle, unless it prove to be O. parvifo- 
ha. There is still greater difficulty in de- 
termining what Linneus himself intended 
in the Species Plantarum, p. 960, he re- 
fers to his Flora Zeylanica, n. 173, again 
in that work he quotes Melastoma scabra 
trinervia of Burmann’s Thes. Zeyl., with- 
out any notice of the plate (tab. 72) which 
represents it: indeed, that figure exhibits 
five petals and ten stamens, and resembles 
O. Kleinii more than any species with 
which I am acquainted. Perhaps Linneus’ 
plant is O. Ceylanica. 
I shall present abridged differential cha- 
racters of all the Ceylon species :— 
+ Anthers 8. 
l. O. Ceylanica ; annual, anthers su- 
bulate. 
2. O. truncata; branches hirsute, leaves 
one inch to one inch and a quarter long, 
anthers truncated. 
3. O. parvifolia ; branches nearly gla- 
brous, leaves three to four lines long, an- 
thers truncated. 
+ Anthers 10, acuminated. 
* Leaves crowded. 
4. O. buzifolia ; leaves thick and rigid, 
closely striated. 
** Leaves rather distant. 
9. O. rubicunda ; leaves on rather long 
petioles, scales of the calyx spreading, 
reddish, style clavate. 
O. Wightiana ; leaves nearly ses- 
sile, scales of the calyx adpressed, yellow- 
ish, style clavate. 
. O. virgata ; leaves at length nearly 
glabrous on the upper side, flowers some- 
what umbelled, style filiform, 
8. O.aspera ; branches strigose, upper 
side of the leaves copiously covered with 
adpressed bristles, under hirsute on the 
nerves, and harshly pubescent between 
them, flowers somewhat racemose, style 
orm. 
9. O. Kleinii ; branches scabrous or 
OF EAST INDIAN ACANTHACE, 
hispid, leaves minutely strigose on both - 
sides, flowers shortly racemose, style fili- 
orm. 
10. O. Walkeri; branches shortly to- 
mentose, flowers terminal, solitary, calycine 
segments elongated, style filiform. 
In addition to the above, the only other 
Melastomaceous plant I have seen from 
Ceylon is Melastoma Malabathrica, L.
