The present contribution is essentially similar to its predeces¬ 
sors. 1 It consists of descriptions of five new species and four 
new varieties. One previously described species, Cymbidium da- 
yanum, is for the first time credited to the Archipelago. Pha- 
laenopsis Micholitzii, Aerides Jarckianum, Aerides quinquevul- 
nerum var. album, and Phalaenopsis equestris var. leucotanthe, 
which were known only from their original descriptions, were 
recently rediscovered. A few combinations and changes in no¬ 
menclature are hereby proposed; this is particularly true with 
the species belonging formerly to Trichoglottis which we now 
propose to transfer to Stauropsis. Sarcochilus unguiculatus, 
which was interpreted as a synonym of S. pallidus, is hereby 
validated and elevated once more to a specific rank. All the de¬ 
scriptions in the text have been prepared from living specimens, 
and all the illustrations were made by Messrs. F. Guerrero and 
J. M. Salazar, draftsmen of the National Museum Division, 
Bureau of Science. All the types of the new species and vari¬ 
eties have been deposited in the herbarium of the Bureau of 
Science, with the isotypes in the herbarium of the senior author. 
Available isotypes will be distributed to the herbarium of the 
New York Botanical Garden and to other herbaria.
