he further proposed a terminology to indicate the exact nature of the various 
kinds of type specimens and their taxonomical status. These observations 
and proposals have been embodied in two papers which it is proposed to 
publish in the Gardens Bulletin. 
The Director completed his study of the genus Lomagramma, a group 
of climbing ferns found in forests from Assam and southern China through 
the Malaysian region to the Pacific. Two species occur in the Malay 
Peninsula, and their status could not be determined without a consideration 
of the other species. The result fills a gap in the taxonomy of ferns and 
throws an interesting light on the biology of climbing ferns. Mr. Holttum 
also studied recent fern collections, including those made by himself at 
Cameron Highlands, and prepared a paper containing critical notes on local 
species, additions to the known fern flora of the Peninsula, and the 
description of five new species. The results of this work will be published 
in the Bulletin. 
The Director continued his study of orchid seedlings, and a number of 
new hybrids were raised. An account of the horticultural aspect of this 
work appears in a later section of this report. Three new hybrids flowered 
during the year, and two were illustrated and described in the Malayan 
Orchid Review. One of these is, so far as our information goes, the first 
reported Arachnis-Renanthera hybrids to flower, and shows characters closely 
intermedite between its two parents, Arachnis Hookeriana and Renanthera 
coccinea. Arachnis Hookeriana x flos-aeris proved to be hardly distin¬ 
guishable from A. Main gay i, a species described from Malacca and found 
also in Eorneo and Sumatra. It is thus probab’e that A. Maingayi, which 
has several varieties, is of hybrid origin. A few second generation Spatho- 
glottis hybrids have been raised, but the first hybrids in this genus are almost 
sterile. One second generation hybrid, S. Parsonsii { = S. piicata x S. 
vanoverberghii) crossed with a large white variety of S. piicata, has flowered, 
and will be described in 1937. There is some variation in colouring among 
the progeny, but no noticeable variation in shape or form.
