THE ORCHID REVIEW. 201 
In the Cool house are several interesting things, and amongst them are 
some real gems. Ornithocephalus multiflorus (Rolfe) is a new species, a 
native of Brazil, bearing half-a-dozen graceful racemes covered with small 
pure white flowers. Its compact habit and charming racemes and blooms 
suggest that it would be worth while to introduce more of it. Colax 
Puydtii is another distinct species now in flower, also the handsome Chon- 
drorhyncha Chestertoni, which has bloomed before this season. 
Several other varieties are sending forth their spikes, which will succeed 
those above mentioned. Amongst them are the curious Bulbophyllum 
odoratissimum, Cleisostoma latifolium, the attractive Cycnoches Egertoni- 
anum, and the showy Cynorchis grandiflora with its brightly coloured 
flowers, Habenaria pectinata, and Xylobium scabrilingue. 
Other interesting species showing for flower are Cirrhza viridi-purpurea, 
Liparis elata and Prainii, Microstylis commelynefolia, Pleurothallis 
maculata and several Polystachyas, as P. leonensis, luteola, and rhodoptera, 
and also Satyrium coriifolium and cucullatum. Many others will soon be 
in season, some of them very rarely seen in collections, the more interesting 
of which will serve as materials for future notes. 
ODONTO. 
DENDROBIUM BULLENIANUM. 
DENDROBIUM Bullenianum is an interesting Philippine species, with heads 
of orange-coloured flowers striped with light-red on all the segments, 
which has very rarely been seen in cultivation since its original introduction, 
hence its re-appearance in an importation of D. Dearei by Messrs, F. 
Rancer & Co., St. Albans, is interesting. It was originally introduced by 
Messrs. Hugh Low & Co., and was described in 1862 by Reichenbach 
(Bot. Zeit., xx., p. 214). In 1874 a plant, which had been received from 
the Philippines, flowered in the collection of W. E. Brymer, Esq., and was 
described by Reichenbach under the name of D. erythroxanthum (Gard. 
Chron., 1874, ii., p. 162), but I do see how it can be distinguished from 
the preceding. Both were described as having heads of orange flowers 
lined with red, and both were compared with D. secundum, while the 
differences pointed out seem to be too slight to be of importance. I have, 
however, only seen dried specimens of the latter. D. Bullenianum belongs 
to the section Pedilonum, and its flowers, which measure #-inch long, and 
are very distinct in colour, are borne in lateral heads of about fifteen each.
