E. Br.: the typical species of this section are thejcommon Habenaria 

 Co?wpsea and II. odoratissima and their allies, to which we would 

 add the H. nigra, E. Br., or Nigritella, L. C. Rich., an alpine 

 species very similar in character, and known to hybridize with them 

 with the greatest facility. 2. Tinea, Biv., or Neotinea, Eeichb. f., 

 is the H. intacta, Lindl., distinguished from Gymnadenia chiefly 

 by the lateral processes of the stigma, which vary so muoh 

 throughout the genus. 3. Leucorchis, 0. H. F. Mey., or Bicchia, 

 Parlat., is the European II. albida, E. Br., near to which might 

 be placed the North-American H. tridentata and H. nivea. 4. 

 Perularia, Lindl., two closely allied species, one North-American, 

 the other North-Asiatic. 5. Deroemeria, Eeichb. f., is H. apliylla, 

 E. Br., a curious little aphyllous Abyssinian, and perhaps Arabian, 

 plant. G. Peristylus, Blume (Gennaria, Parlat., Benthamia, A. 

 Eich., and Cybele, Falcon.), comprises the European II. cordata, 

 E. Br., and a considerable number of small-flowered African and 

 Asiatic species. 7. Coeloglossnm, Hartm., was founded on the 

 European H. viridis, E. Br., and should probably include Platan- 

 thera satyrioides, Eeichb. f. Lindley gave the name C'celoglossum 

 (changed by Fries to Lindblomid) to a different group compri- 

 sing five Asiatic small-flowered species which might be referred 

 to Peristylus, but closely connect that section with Plataniheva. 

 Chceradoplectrum, J. C. Schau., is evidently, from his figure, the 

 Cceloglossum lacertiferum, Lindl., transferred to Hdbenaria in the 

 ' Flora Hongkongensis.' 8. Phyllostachya, a section I should 

 propose for several rather large Asiatic species with one tropical- 

 African one, distributed by various authors in the genera 

 Gtjmnadenia, Platanthera, and Habenaria, and collected by Beich- 

 enbach under Gymnadenia, all more like the typical Platan- 

 thera than the typical Gymnadenia in structure, and all remark- 

 able from the leaves passing into large foliaeeous bracts which 

 give them a peculiar habit. Nearly allied to them is the East- 

 Indian II. iutea, "Wight, distinguished in the whole genus by the 

 sepals and petals connivent into a globular perianth. 9 and 10, 

 Blatanthera and Habenaria proper, comprise the great mass of 

 the genus which most botanists consider as being susceptible 

 of distribution into two great groups ; but the various characters 

 assigned have broken down in detail, and it would require a much 

 longer study than I have been able to give to them, especially 

 from dried specimens, to ascertain the real value of several appa- 

 rent distinctions. It would appear, however, that Platanthera
