tainable the pods are relished by goats; and for scenic 
effect there is perhaps no prettier tree, ^growing as it 
often does on a flat rocky subsoil which will carry no 
other tree. In alluvial soil it ..responds jfreely and gives 
better growth, on hot rocky banks it is common, but it is 
never found in high dense forest. Bark rough, thick, 
dark; formerly much used locally in ,the tanning oft .leath- 
er, and even now, at about hal^f the price per ton as com- 
pared with black watrtle, it pays to employ it] for ; local 
use, but not for export, as the percentage of tannin for 
the bulk is too low. 
"The doom- boom is the host of an innumerable lot of 
pests, being often cleared of foliage by caterpillars of 
several large moths, and by bagworms; its timber is often 
bored by Apate dorsalis and Chrysobothris dorsata; certain ants 
occasionally inhabit the thorns and induce a most thorny 
development, sbrange gall abortions or malformations of 
pods are caused by a fungus; another fungus OEcidium orna- 
mentale makes artistic floriated curls of the young twigs; 
and Loranthus and mistletoe are frequent parasites. 
"Doorn-boom makes a strong rough hedge if soaked seed 
is sown in line and kept watered till germination has 
taken place. It is also useful for sowing in beds of in- 
termittent rivers with a view to arrest silt during future 
floods. It suffers severely during soft snowstorms, the 
horizontal branches and foliage breaking under a heavy 
weight of snow." (Sim, Forest Flora of Cape Colony.) 
Achradelpha mammosa (L.) Cook. ( Sapotaceae . ) 39357. 
Seeds of the sapote presented by the Costa Rican National 
Museum, San Jose. "The sapote has an open c crown of large, 
lanceolate, coarsely- veined , deciduous leaves, and fruit 
with yellow flesh and a firmer and more uniform texture 
(than the sapodllla), not crisp like the flesh of an ap- 
ple, but more like that of a cooked carrot or squash? The 
triangular-fusiform seeds of the sapote are very large and 
thick and have the whole inner face covered by an enormous 
hilum. The sapote is of no commercial v importance s \though 
the fruit is used extensively for food by the native pop- 
ulations of Central American regions and the West Indies. 
It ascends into the plateau regions of Central America."
