Walter Fox, assistant in the Singapore Gardens, collected a 
small number of plants in Muar, and Robert Derry, while in charge 
of the Gardens and Forest Department in Malacca, obtained a large 
collection of Malacca plants. Two Eurasian assistants in the 
Forest Department, S. Goodenough and Holmberg, added many 
specimens obtained during their forest work in Singapore and 
Malacca. 
Lieut. H. J. Kelsall (now Lieut.-Col., D.S.O.) made an im¬ 
portant collection in an expedition from the east to the west qoast 
of Johor in company with Harry Lake in 1897, and also collected 
on Bukit Hitam in Selangor. 
Alfred Dent Machado, miner and planter, sent plants from 
Legeh, Kwala Lipis, and Kamuning, in Perak. He died in 1910. 
Borassus Machadonis is named after him. 
E. RosTADO^sent the only plants known from Tringganu. 
Sir Walter Napier, Attorney-General, obtained specimens 
from Negri Sembilan, including Webera Napieri. 
Warren D. Barnes made a collection on K’luang Terbang in 
Pahang in 1900. He died in Hongkong in 1911. 
Dr. John D. Gimlette sent a number of plants from Kota 
Bharu and Kwala Lebir in Kelantan, and published a useful book 
on Malay poisons and charm-cures, 1915* besides other works on 
local diseases and materia medica. 
Alfred M. Burn-Murdoch, born 1868, was Conservator of 
Forests in the Malay Peninsula from 1904 till his death in Selangor 
in March, 1914. He collected a certain number of plants and 
published two numbers of “ Trees and Timbers of the Malay 
Peninsula,” 1911-1912. His name is associated with Alpima 
Murdochii. 
Mohammed Haniff, overseer in the Penang Gardens from 1892 
and in complete charge of them from 1912. He collected plants in 
Penang and also in Lankawi, Kedah, and on Gunong Kerbau in 
Perak, and has made many valuable additions to our knowledge of 
the flora. 
Herbert C. Robinson, director of the Federated Malay States 
Museums from 1903, and Mr. CiiAREBe Boden Kloss did in¬ 
valuable work in their explorations of the mountains of the 
peninsula. Mr. Robinson was the first man to ascend Gunong 
Tahan in Pahang, the highest mountain in the peninsula, bringing 
down with him the first collection of plants made above the altitude 
of 6000 feet. He and Mr. Kloss also collected plants on the moun¬ 
tains of Perak, Selangor, and Kedah, and in Lankawi islands and 
other places. Without these two collectors we should have known 
but little of the highland flora of the peninsula. I had the pleasure 
of accompanying them on several of their explorations, notably to 
Telom and Temengoh, Gunong Tahan, and Pulau Adang. Accounts 
of their botanical collections are published in the Journals of the
