SUPPLEMENT TO ORCHIDEJE, WITH ADDITION'S AND 

 COEEECTIONS. 



During the elaboration of the OrcMdece for this Flora, very large collections of 

 species, from many parts of India, were being received at intervals by the Herbarium 

 of the Royal Gardens, Kew, especially from the rich stores of the Royal Gardens of 

 Calcutta, together with the loan of a magnificent series of original drawings of Orchids 

 from the game source. The most important of these collections were Malayan, abound- 

 ing in novelties, from Penang, Perak, Singapore and Malacca, made by the late Father 

 Scortechini (presented, together with the loan of the Rev. father's pencil drawings 

 of many species, by the Government of Perak), by Kunstler, a collector sent from 

 the Calcutta Bot. Gardens by Dr. King, by Curtis, Hullett, Wray and Ridley. 

 Important collections were also sent by Mann, from Assam, Bhotan, and the Khasia 

 hills; by Gamble (on loan) from various parts of India ; by Duthie from Garwhal ; 

 by Clarke from Sikkim, the Khasia hills, and Bengal, together with a few irum 

 Central India; and (on loan) by Dr. Trimen from Ceylon. These successive arrivals 

 necessitated many consecutive revisions and emendations of the work already pre- 

 pared, some printed, some in the press, and some in inss., besides adding many 

 species and some genera to the Indian Flora. 



Vol. v. p. 667. KEY TO THE TEIBES AND SUBTRIBES. 



The Key to the Indian Genera Subtribes and Tribes was extracted, with a few 

 modifications, from that prepared by Bentham for the Genera Plantarum; which, 

 whether as regards the* difficulties that attend the analysis of the plants of 

 this most complicated Order, or the chaotic state into which the family had fallen 

 since Lindley's days, is a masterpiece of research and scientific taxonomy. As may 

 be supposed, the detailed examination of so many Indian genera and species as are 

 contained in this Flora (about 1400), and of a large proportion of which Bentham had 

 no knowledge, or only a superficial one, has suggested a few emendations in his 

 classification, but these are very slight, and I shall notice them in their order, in the 

 following pages. 



Sub-order MALAXEJE. I have departed from Bentham, in including LIPAEIE^; 

 and MALAXED under one sub-order. The essential character of Liparlefe, the 

 incumbent anther, fails in a great measure when Oberonia is placed in it, for the 

 pollinia of this genus are as Griffith points out (Notul. iii. 273) in 0. anthropophora 

 and trilobata (ensiformis, Liudl.) at first accumbent ; and in these and others he 

 describes them as " accumbenti-iucumbentia." Added to this the habit of Micro- 

 stylis, which is placed in Malaxem, is that of Liparis ; and of Oberonia, which is 

 placed in Lipariece, is that of Malaxis. The clinandrium is so minute in Oberonia 

 and Microstylls, that I have little confidence in my own results obtained by softening 

 these parts in dried specimens, but my impression is that in Microstylis the anther 

 will be found to both accumbent and incumbent, very much as in Oberonia. Lastly 

 the pollinia of Oberonia are variously described and figured as 2 or 4. I think
