THE ORCHIDOLOay OP IKDIA. 3 



§ I. Apoeum, Blume, 



The ancipitous leaves clearly distinguish this group from all 

 other Dendrobia. The genus Oxystophyllum differs in nothing 

 except having only two globose pollen-masses instead of four. 

 D. (Aporum) sinuatum of the ' Bot. Eegister, 1841, Misc. No. 3,' 

 which has quite the habit of Oa:. carnosum, seems to connect the 

 two genera ; for although it has four pollen-masses, two are much 

 smaller than the others, as if rudimentary*. 



* Flores terminales et laterales. Caules apice scepe aphylU.

 History, iv. 376 ; lb. v. 369).

His erroneous description of the lip of this plant was corrected 

 by Grriffith in a later paper : the specimen in my herbarium which 

 I refer to here differs in the lip being too broad to be called 

 " linear-oblong" ; but I have seen nothing else to which Griffith's 

 description will apply.

A flower in the Hookerian Herbarium shows this to be the 

 Macrostomium aloifolium, Blume, which is confirmed by one of 

 Kuhl and Hasselt's unpublished drawings. It is, however, not 

 the Herha supplex quinta of E-umphius, as I formerly suspected, 

 the figure of that plant certainly representing D. {A.) suhteres. 

 According to G-riffith this is also the Dend. acinaciforme, Boxb. 



74. D. (A.) LoBBii : caulibus apice aphyllis, foliis scalpeUiformibus 

 duplo longioribus quam latis; floribus minutissimis terminalibus ; se- 

 palis recurvis ; labello erecto carnoso trilobo ; lobis lateralibus bre* 

 vioribus unguiculato.

This looks like a very small state of D. Serra ; but the leaves are 



* Prof. H. Gr. Reichenbach reduces Oxystophyllum to Dendrobitim. Neither 

 the materials with which he has favoured me nor those in my own herbarium 

 enable me to form a decided opinion on the subject. In fact that whole genus, 

 if it be one, is in inextricable confusion. A fragment of Blume's Sarcostomat 

 and a drawing of the details of its structure, for which I am also mdebted to 

 my learned friend, seem to show that that genus should be preserved. The 

 pollen-mass<^ are represented as having long tails, and have no resemblance to 

 Blume's figure.
