6 PROFESSOR LINDLEY'S CONTRIBUTIONS TO 
* Flores terminales. .Labellum margine continuum. 
83. D. Macrei, Lindl. Gen. & Sp. Orch. No.3. (? D. nodosum, Dalzell 
in Hook. Journ. iv. 292.) 
Ceylon, Macrae; Nilgherries, Madras Herbarium, J. D. H. (27)? ; 
Khasia, at the height of 4000 feet, J. D. H. (26)? 
The flowers of D. Macrei were described as having an entire 
lip, upon the faith of a Cingalese native drawing. It is, however, 
very doubtful whether such is their structure, and I ean hardly 
doubt that Dalzell’s D. nodosum, of which I have examined per- 
fect flowers out of the herbarium of my late lamented friend Dr. 
Stocks (No. 30), is the same plant. Its leaves, indeed, are nar- 
rower, and its pseudo-bulbs less unequal-sided, in the specimens 
before me. Of Dr. Hooker's No. 26, from Khasia, the flowers 
are unknown, but are said to be solitary and white; the leaves 
are not half the width of D. Macrei, and the pseudo-bulbs are so 
slender as to be scarcely distinguishable from the main stem. All 
are nearly allied to D. flabellum of Reichenbach. 
84. D. PuMiLUM (Griff. Notul. iii. p. 315); pseudobulbis clavatis te- 
tragonis nitidis diphyllis, foliis brevibus ovato-oblongis obtusis, flo- 
ribus inter squamas subsessilibus, sepalis petalisque acuminatis, mento 
attenuato incurvo ovario subzquali semifisso, labello unguiculato 
oblongo nudo dimidia superiore acuminata crispa. 
Mergui, on trees, Griffith (24 and 1175). 
Flowers small, white, sweet-scented, according to Griffith, whose 
description is, however, not quite exact. In habit it resembles 
D. tetragonum. 
85. D. LABUANUM; pseudobulbis parvis diphyllis secus caulem arcte 
adpressis, foliis obtusis anguste ovalibus obtusiusculis, floribus soli- 
tariis, labello trilobo intra apicem papilloso axi elevata carnosa 
abrupta. 
Borneo, T. Lobb. 
This is related to D. cymbidioides and its allies, but the flowers 
are much smaller. 
86. D. BRACHYPETALUM ; pseudobulbis parvis monophyllis secus cau- 
lem arcte adpressis, foliis obtusis, floribus geminis subsessilibus, sepalis 
acuminatis, petalis acutissimis duplo brevioribus, mento brevi, labello 
brevi oblongo acuto bicarinato. 
Java, T. Lobb in hb. Hooker. 
A. small species with flowers not larger than in an Oberonia. 
The short acute petals and lip are unusual.
