R. duuricum, Linn., from which it is distinguished by having larger 
thinner acute leaves, which fall off before the flowering stage, and 
larger more numerous flowers. ie Kew plants were obtained by 
purchase from a firm of nurserymen in Yokohama in 1907. 
Pittosporum Coleios is a New Zealand species which, though 
tender in most parts of the United Kingdom, flourishes out-of-doors 
in the gardens of Mr. T. A. Dorrien Smith, Tresco Abbey, 
Isles of Scilly, from which the material for the figure was sent. 
Notylia trisepala is a small epiphytic orchid with a long pendulous 
raceme of very small pale green flowers, and is a native of Mexico. 
The specimen figured flowered in the garden of Mr. W. E, Ledger, 
at Wimbledon, and was presented by him to the Kew collections, 
The Stem Bleeding Disease of the Cocoanut.—A pet illustrated 
account of a fae disease of the Cocoanut, by . Petch, is 
contained in Circular No. 22 of the Royal Relais Gardens, 
Ceylon. The leading symptoms of “ Bleeding disease” are the 
exudation of a dark-coloured sap from cracks in the “ bark.” This 
sap is somewhat viscid and gradually forms a patch of perceptible 
thickness, which soon turns black. These patches vary much mn 
size, being sometimes quite small, in other cases several fee 
in length and 6 inches or more broad. The effect of the ae 
varies much with the age of the tree, and the injury is most severe 
' up to 40 years of age, and in severe cases the disease hollows out 
the stem almost to the bud, yet without killing the tree. In trees 
under 10 years old, the external patch is usually quite small, and 
gives no indication of the extent of internal decay, which may be 
very considerable. On trees over 40 years old, although the 
patches may be num erous, the substance of the trunk is not 
materially injured, the “wood” being generally so hard that it 
resists the attack of the fungus. An sa aghal series of cultures 
and inoculations have proved the disease to be caused by a fungus 
named Thielaviopsis paradoxa, v. Hohn. (Thielaviopsis ethaceticus, 
Went.), a well-known parasite of the sugar-cane. 
Notwithstanding the serious nature of the disease, the trees are 
rarely, if ever, killed outright, neither is there any material 
diminution in the crop, even when the trunk is hollowed out. 
All varieties of the cocoanut appear to be equally susceptible to 
the disease, though the “ King cocoanut” more than the 
others when trees of the same age are consider 
The treatment recommended is to sec lotaks cut out the diseased 
portion of wood, and to cover the wounded surface with coal tar. 
All diseased portions should be collected and burned, and not 
allowed to lie on the ground at the base of the trun 
A short reference to this disease appeared in K.B. "1908, p- 310. 
A Disease of a Cacao ore —Diplodia cacaoicola, P, Henn., was 
described on Cacao from p Samora in the year 1896; more 
recently it has aie reported to occur in Ceylon, Java, Samoa, 
urinam, West Indies ae i St Thomé (West Africa). It may, 
therefore, be said to be parasitic on the cacao plant wherever Bode is 
cultivated to any appreciable extent. Whether the species
