16 PHALJiNOPSlS. 



second species in the Philippine Islands in 1838, which by an 

 unfortunate error Dr. Lindley referred to the P. amahilis of Blume, 

 but from which it is clearly distinct. Ten years later a third 

 species, /'. rosea, was sent to our Exeter firm from the Philippine 

 Islands by Thomas Lobb, who also sent with it P. intermedia, 

 since proved to be a natural hybrid between P. Aphrodite, Cuming's 

 discovery, and P. rosea. During the next fourteen years the number 

 of species from various sources had increased to eleven, up to the 

 time when the genus was monographed by Reichenbach in the 

 first part of his Xeiiia Orchidacea II., which he published in 1862. 

 Twenty years later, when revising the Orchide^ for the Genera 

 Plantarum, Mr. Bentham estimated the number of species at 

 fifteen, but so rapidly were additions made between 1875 — tb, 

 that Mr. Rolfe enumerates thirty-four species in his revision of the 

 genus published in the Gardeners' Chronicle in 1886; but as this 

 number includes three or four that must be reduced to varieties or 

 synonyms of other species, and one or two others that are 

 undoubted natural hybrids, the actual number of known species 

 may be fairly estimated at about thirty, two-thirds of which are in 

 cultivation. 



Mr. Bentham admitted but two sectional divisions, which are thus 

 distinguished : — 



EuPHALiENOPSis. Petals much broader than the sepals, and contracted 



at the base ; lip with two antenna3-like appendages at the apex, but which 



are sometimes reduced to small teeth. 



The included species are amahilis, Aphrodite, Sanderiana, Schilleriana, 



Stuart/'ana, and the hybrids in the parentage of which these species have 



participated. 



Stauroglottis. Petals equal to, rarely smaller than the sepals ; the 



middle lobe of the lip entire,* without the apical appendages of 



EUPHAL^NOPSIS. 



This section includes amethystina, Boxalli, Cornu-cervi, Liiddemanniana, 

 Mannii, maculata, Marioi, Parishii, rosea, speciosa, sumatrana, tetraspis, 

 violacea and others known to science but not in cultivation. 



Besides those enumerated above, there are two other interesting species 

 in cultivation that cannot properly be included in either section, viz., 

 Phalcenopsis Loivii and P. Esvieralda. Mr. Bentham included the first 

 named in Euphal^nopsis, but it differs from all the species in that 

 section in two important characters, viz., the absence of the apical
