68 PROFESSOE LINDLEY's CONTRIBUTIONS TO 



this for it. There are, however, these differences : the leaves are 

 twice as broad and much less acuminate ; the spikes are so dense 

 as to be almost ovate ; the lateral sepals are not acuminate ; the 

 lip is more rounded at the point and without the raised median 

 line, instead of which there is only a slight convexity above with 

 a corresponding concavity below. The linea verruculosa, ascribed 

 by Blume to his E. annulata, does not exist in Zollinger's no. 15 

 of his second collection, which I take for that species ; but there 

 is a distinct elevated even midrib, with a slightly raised . line on 

 either side.

There is nothing in the structure of the plants of this section, 

 as far as I am acquainted with them, that corresponds with the 

 character proposed by Prof. Blume in his Mus. Lugd. Bat. ii. 182. 

 Undoubtedly a protuberance at tlie foot of the column does 

 sometimes occur, but it affords no sectional mark ; for if it exists 

 in JE. nutans, it is not to be found in E. Khasiana, which is only 

 distinguishable upon careful examination ; and it is a mere rudiment 

 in -E7. hicolor, another very closely allied species. The siliquose 

 fruit is of as little importance. I think, however, that the section 

 may be conveniently adopted for all the caulescent species whose 

 flowers, whether lateral or terminal, are solitary or in pairs, and 

 arise from among empty coloured bracts. Such is the principle 

 upon which the following have been collected. 



A. Mowers terminal. 



309. E. TRUNCATA ; foUis 3 lanceolatis terminalibus apice subaequa- 

 hbus, floribus geminis ovario tomentoso, sepalis oblongis obtusis, pe- 

 tahs subsequalibus antrorsum arcuatis, labello carnoso truncate hnea 

 media tenui elevata infra apicem triplici.

" Elowers white." The lip has two small ovate lateral lobes ; 

 but the middle lobe is obsolete, appearing only in the form of a 

 broad line lying between the side lobes.

Wight's figure of this is unusually good. The withered reflexed 

 sheath at the base of the last joint of the stem seems to be cha- 

 racteristic of the species.
