As stated in the Kew Bulletin (1897, p. 337), Gutta Percha 
‘isa very ee plant to propagate by cuttings, but this can 
done.” However, Mr. Ridley, the Director, Gardens and 
Forest Department, Singapore, states that “the tree always comes 
up again when cut down.” The unes — information 
seems to point to greater success in propagatio 
EXTRACT from letter from Director, Gastéás and Forest 
Department, Singapore, to Royal Gardens, Kew, dated 
February 16, 1898. 
“A rustie — ees some cuttings of Gutta Percha 
from Borneo which seem to be very Eee. $ They appear to be 
cut from pretty thick. Soupis mgl ted over with wet mud, 
and apparently are very healthy, errem out strong shoots. I 
will find out how it is done, as it seems more successful than 
anything I have ure Pod seen.” 
The Toonu or Tunu.—In poesie me: of a misconception of the 
Spp of the native tunu" in British Honduras, 
me confusion has arisen, for: S Roh Kew is partly responsible. 
B Dr. D. Morris's baad of British Honduras it is stated (p. 74) 
that this is the na name of Castilloa elastica, the principal 
rubber tree of tem peat It is now NN veia that the 
name is properly a pee. to another speci till imperfectiy 
known oud E Planters sent specimens w 7 astilloa elastica 
as the “tunu,” so that in Us absence of adequate specimens of the 
true * funt^ it has been assumed at the Herbarium that only one 
species was concerned, and this opinion has been communicated to 
ariu Museum, 
with the result of ascertaining that two species of Castilloa. exist 
in oe Honduras. This was pur established by Sir Joseph 
er (Trans. Linn. Soc. Bot. 2nd series, ii, pp. 209-215, 
iioc 27 and 28), where he describes and figures four forms of 
Castilloa, including the *tunu;" but he does not attempt to 
decide their rank. What he regarde d as typical, C. pn is 
described x some length, and its distribution given as Mexi 
from lat. 21° southward, through Guate maja, E Salvador, 
on nduras, Nica a and Costa Ricá. anit ars the na

“caucho,” or Darien rubber plant, which kim refers to 
(Peruvian Bark, p 453) as Castillon merihamiang Collins, a 
yay different plant, and probably no th genus. 
ra paper is illustrated ps a coloured figure of the 
Darien lant, d in Ceylon. This is not specifically

different from “Castillon elastica. Number 3, of which only the 
fruit is figured, is from Honduras, and is also undistinguishable 
from C. elastica. Number 4, of which only the fruit was 
known to Sir Joseph Hooker, is the “tunu” of Honduras. It 
differs essentially from C. elastica in the ovaries and drupelets 
ke completely embedded in the receptacle. In all the forms 
C. elastica the drupelets are easily separated. Since the 
rabos of i Joseph Hooker's paper, Kew has received 
some leaves of a tree from Mr. Rowlan LUN. Dalek; which hs
