GUMS, RESINS, AND KINOS. 237 
5. Bombax malabaricum, DC., (Syn. B. heptaphyllum, Cav. ; 
Salmalia Malabarica, Schott.); N.O., Malvacez, B.F1.,i., 223. 
The ‘“‘Simool Tree,” or ‘‘ Malabar Silk-cotton Tree” (of India). 
The gum (Mocharas or Mucherus) only exudes from portions 
of the bark which have been injured by decay or insects; incisions 
in the healthy bark produce nothing. It is very astringent, and 
is used both by Hindus and Mahometans in diarrhoea, dysentery, 
and menorrhagia, in doses of from 40 to 50 grains for an adult. 
(Dymock, Materia Medica of Western India.) Waring (Pharm. 
of India), however, says that this gum, or rather product of a 
diseased action, is incorrectly referred to this species, and that its 
botanical source is unknown.

6. Ceratopetalum summiferum, S., N.O., Saxifrage, B.FI., ii., 
442. 
‘‘Christmas Bush,” (For other names, see ‘‘ Timbers.”) 
By well wounding the tree, or, better still, by felling a tree 
and cutting it into logs, there exudes a kino of exceptionally beau- 
tiful appearance. It is of arich ruby colour, perfectly transparent, 
very tough, though when it has become thoroughly hard it breaks 
with a bright fracture. It is exceedingly astringent, sticks to the 
teeth, and obviously contains a large proportion of gummy matter. 
The author having only recently collected the substance, is unable 
to give further particulars in regard to it at present.

7. Eucalyptus spp, N.O., Myrtacez. 
Many trees yield their kino in a viscid state on tapping a gum 
vein in spring or autumn. Exposure to the air usually hardens it 
almost immediately. As a very general rule, the kinos are col- 
lected naturally exuded and hardened on the outside of the bark. 
There is a great difference between various species in regard 
to the yield; £. corymbosa, for instance, producing it in the 
greatest abundance, while some yield it so little that it has not been 
recorded as having been found on them. But there is no doubt 
that on every species it will be found in at least minute quantity.
