Malay Peninsula ; (2) Detarium senegalense, an African tree, which yields a substitute for mahogany as well as fruits that can be eaten 
cooked ; (3) Pterocarpus indicus, the Burmese Padouk, which has a valuable timber ; (4) Parkia speciom, the Petai, with pods beloved 
by the Malays as a seasoning; (5) Alhizzia Lebbek, which is the chief roadside shade-tree of the Levant; (6) Ccesalpinia coriarea, 
the pods of which are the commercial tan, Divi-divi ; (7) Hymensza courbarilf a South American tree, which seems to produce its hard 
timber at an unusually rapid rate ; (8) Pithecolobium eUipticum, a tree of Malaya, with saponin in its bark to a sufficient extent for it 
to be used as a fish-poison and as a hair-wash ; (g) Andira jamaicensiSf a pretty bush of the West Indies, Brasil, and the Guinea Coast of 
Africa, a member of one of those interesting American genera which cross the Atlantic ; (10) Gliricidia maculatat another American 
bush, of great beauty when it flowers well, which came to the East across the Pacific at the hands of the Spaniards in the eighteenth 
century because it was useful for shading cacao ; (ii) Saraca mdica, the Asoka tree of the moister parts of India, a sacred tree and 
much used medicinally ; (12) Browma macrophylla ; (13) Pentaclethra macrophylla, an African tree, the oily seeds of which are eaten, 
and have been tried in the mills of Europe ; (14) Banhinia semibifida, a local climber, now getting rare in a wild state ; (15) Derris elUptica 
and (16) Derris malaccensis, sources of tuba. Tuba root grated has for ages furnished to primitive man in Malaysia a material for stupe- 
fying fish so that they may be caught. It is also used sometimes in arrow poisons. But it would seem to have been immigrant Chinese 
who adopted it as an insecticide ; and through them it has come into European use. 
Eight of the sub-families of Leguminosse are represented thus on Lawn F ; and seven more are represented in other parts of the 
Gardens. It has been found impossible to grow any of the Australian Podylirieae, of which 36 have been tried, the north- temperate 
Loteae and the Trifolieae, except Parochetus communis, which can be kept alive in a pot* 
Near the Dell end of the path, the visitor will find the following Dipterocarps : — Balanocarpus Hemsleyanus, 
Isoptera borneensis and Dryobalanops ovalifoUa* If they continue to grow well they will form considerable trees ; 
they are natives of the Malay Peninsula* The most interesting of them is Isoptera borneensis, because its seeds yield 
tenkawang fat. It is found on river-sides from Sumatra to the southern Philippines. Its fruits are produced at irregular 
periods in large quantities, and floating, can be swept together on the water with ease ; if collected and crushed before 
rancidity sets in, a pleasant tallow-like fat is obtained, for which the demand is greater than the supply. Dryobalanops 
ovalifolia is the Keladan of the Malay Peninsula, and is a close ally of the tree which yields Bornean Camphor,
