126 THE ORCHID REVIEW. (May, 1916. 
ZYGOPETALUMS AND ALLIES.—Here we have a most interesting class of 
plants, including Bollea, Pescatorea; Warscewiczella, Huntleya, Promenza, 
Batemannia, and Kerfersteinia. Z. Mackayi may be regarded as a typical 
- example, and is the best known, but the majority do not resemble it in the 
least. Most of the others, except Promenza, possess no pseudobulbs. 
There are several Zygopetalums, including hybrids, which are either in 
bloom or just past their flowering period, and any that are about to produce 
roots from the partially-made pseudobulbs may have new rooting material 
afforded them, should they be in need of it. Zygopetalums succeed in a 
humid temperature of about 60°, whilst Promenzeas succeed in shallow pans 
suspended in a shady cool part of the Odontoglossum house. The quaint- 
flowered and really wonderful Chrondrorhyncha Chestertonii succeeds 
under the same treatment. Do we, as growers ever realise the marvellous 
character of these works of nature? I think not, and surely there are no 
more wonderful things in the whole universe than the flowers of many 
plants which pass regularly through our hands, for example, the sensitive 
lip of Masdevallia muscosa ! 
GENERAL REMARKS.— During the present month many will again pay 
their annual homage to the Mecca of all Orchid lovers. Many others will 
be absent, engaged in a struggle of a different character; but let us hope 
that their work in that sphere may speedily come to an end, and that they 
may soon return to the peaceful work of horticulture, of which Orchid- 
growing forms no mean part. 
PLEIONE De Lavayl!, Rolfe.—This beautiful Chinese Pleione has now 
bloomed in cultivation, a flower having been received in the collection of 
H. J. Elwes, Esq., Colesborne, Glos. Mr. Elwes states that the plant was 
sent home by Mr. G. Forest. The species was originally discovered in the 
high mountain region of Yunnan, and was described from dried specimens- 
It has much of the general character and appearance of the now well-known 
P. yunnanensis, but has longer segments, which measure as much as 
24 inches long, and the petals not exceeding the sepals in length. The 
colour is bright rose-purple, with some red-brown markings on the well- : 
fringed lip, on the disc of which are five crenulate keels. The pseudobulbs 
are subglobose, smooth, dark green, and nearly an inch long. It is an 
interesting addition to the genus, and there are two other Chinese species 
which, so far as we know, have not yet appeared in cultivation, namely, P. 
bulbocodioides and P. grandiflora. It may be added that a revision of the 
genus appeared in an earlier volume (O.R., xi. pp. 289-292), and that two 
or three other species have since oe: described, one of which, P. 
formosana, Hayata, was brought home alive, and has flowered both with 
Mr. Elwes and at Kew. R.A.R.
