Pulau Pawai and Pulau Senang. Collections were also made at Malacca on 
Pulau Besar, Pulau Nangka and Pulau Dodol, one of which must have been 
the collecting locality of the collections cited by Ridley. This tree is obviously 
commoner than originally thought. 
32. The Keeper also found Iyengaria stellata, a new marine algal record 
for the Malay Peninsula at Tanjong Gul. It has subsequently been found 
at B/akang Mati. Monogramma trichoidea, thought to be extinct on Singapore 
Island was rediscovered. The locality is not being disclosed since the plant 
is extremely scarce and should never be taken up by the roots. A rare lycopod, 
which may be L. dalhousianum, has also been found, but unfortunately near 
a main road where it can be seen by the public. Its expectation of life can 
only be very limited. There used to be several species of Lycopodium m 
the Water Catchment Area growing on trees as epiphytes but they are fast 
disappearing. They make decorative hanging plants and have probably been 
picked for this purpose. 
33. More cases of mushroom poisoning occurred during the year and 
it is now certain that the poisonous species is Lepiota morganii. In view of 
this it is interesting to note the possible identity of Chendawan Kelemumur 
(scurfy fungus) in prescription 523 of “The Medical Book of Malayan Medi- 
cine” in the Gardens’ Bulletin VI (3) October 1930, p.p. 417 and 432. When 
the commentary on this book was prepared Chendawan Kelemumur was 
unidentified. None of the present cases of poisoning by L. morganii has 
proved fatal, nor more serious than a very unpleasant discomfort of vomiting 
and diarrhoea. This violent emetic and purgitive action may indeed be a 
saving grace and the character upon which the Malay bomoh relied to shift 
more potent poisons from the intestines when he prescribed this fungus, 
adding — where the modern physician would put “Fiat haust” without mention 
of the outcome — confidentially” . . . and let him be relieved.” 
XV. EXCHANGE AND ACQUISITION 
34. Specimens were again distributed to the usual botanical institutions 
outside Singapore. The number distributed was 2,672, considerably lower 
than normal owing to the diversion of botanical staff time to the Kinabalu 
expedition. Specimens received in exchange or as gifts totalled 2,824 which 
is also a reduction on previous years. The greatest number came from North 
Borneo, with the Forest Research Institute, Kepong, second. Herbarium 
Bogoriense third and the Kuching herbarium fourth. Details are given in 
Appendix V. 
XVI. TAXONOMY 
35. Mr. Sinclair continued his work on Malaysian Myristicaceae (Nutmeg 
Family) in collaboration with the Flora Malesiana Foundation. The manu- 
script revision of the genus Knerna, prepared in 1960, passed through the 
printer and appeared as Florae Malesianae Precursores— XXXI. The Genus 
Knerna (Myristicaceae) in Malaysia and outside Malaysia, in the Gardens’ 
Bulletin, 18 (3), December 1961. 
36 Work was begun on the genus Myristica. This is the largest genus 
of the family with about 70 species and contains the most unsolved problems. 
Several of the type specimens from New Guinea were destroyed in Berlin 
during the recent war. Many isotypes have fortunately been located in other 
herbaria, but some of the destroyed types of which isotypes have not been 
found elsewhere probably were never duplicated. In some cases a species 
is known by only one or two gatherings and the material is inadequate for 
a good description to be made. Nor do these sheets bear detailed field notes 
on the general appearance of the tree, bark characteristics and other features.
