roe valuable ak is steadily progressing, and Parts VI. & VIL. 
are now before us, the former treating of Cwlogyne, Kpidendrum, 
t chaglittie: Phaius, Thunia, Chysis, Pleione, Calanthe, Diacrium, 
Nanodes, and a few other small genera, the latter containing Phale- 
nopsis, Aérides, Vanda, Angraecum, Saccolabium, and noi genera. 
Only those species are mentioned which are or have been 
cultivated in the _gilass-houses of Great Britain. Thilesd, unless

Part VI. of the Manual, exclusive of that highly interesting and 
distinct species which has been referred to Epidendrum by the 
authors of the Genera Plantarum, but which is more widely known 
under its old generic name of Nanodes. This is ot to be wondered 
at, considering how very different in habit Nanodes is from the 
ordinary Epidendrums. [For the same reason, Pleione is kept

distinct from Phaius, from which it is distinguished by having ‘no 
pseudo-bulbs, but jointed, biennial stems, slightly nodose, and
