238 THE ORCHID REVIEW. [ AUGUST, 1903. 
-ground, and in various structural details. The species in flower were very 
numerous, and included eighteen forms of M. Chimeera, differing in size, 
colour, and other details of the flower. Other species of the Saccolabiate 
were M. bella, M. Vespertilio, the rare and striking M. trinema, M. radiosa, 
M. Gaskelliana, M. Carderi, and M. Chestertoni. M. coccinea was 
- represented by several distinct forms, allied species in flower being M. ignea 
and M. racemosa. Of M. muscosa there were two well-flowered examples, 
while close by was a good plant of the larger and much darker M. xipheres, 
whose lip, it is interesting to find, opens and closes in precisely the same 
way aS that of M. muscosa. The lips were found wide open, but in each 
‘case a slight touch on the tubercle-like crest caused them to close rapidly, 
the motion being somewhat gentle at first, but suddenly terminating in a 
quick jerk. A detailed account of this remarkable mechanism and its use, 
and of the other two species of the section Echidne, was given at pp. 
228-230 of our last volume. Of the Triaristella group we noted M. gemmata, 
M. triaristella, and M. triglochin, and of the Caudate, M. hieroglyphica, 
M. Estrade, and M. caudata var. xanthocorys. Other interesting forms 
wwere M. corniculata and its variety inflata, in good examples, M. 
Reichenbachiana, M. melanoxantha, M. ventricularia, M. demissa, 
M. cupularis, M. calura, M. maculata, M. marginella, M. infracta, 
M. nidifica, M. torta, and M. xX Rushtoni. 
Restrepias are also well represented, the rare R. trichoglossa and four 
other species being in flower, together with Physosiphon Loddigesii, 
Scaphosepalum verrucosum, Octomeria diaphana, two species of 
Cryptophoranthus, Stelis Miersii, with four others, and ten species of 
Pleurothallis. |The more interesting among the latter were P. leacopyramis, 
-a neat little plant bearing eight racemes of pure white flowers ; P. Simmler- 
jana, an allied species with dark red-purple flowers, P. inflata, remarkable 
for the deeply concave united lateral sepals, P. stenopetala crowded with 
-flowers, P. macroblepharis, and a good example of P. scapha. 
Several species of Dendrobium were in flower, including an exceptionally 
fine form of D. atroviolaceum, D. bicameratum, D. Bensonz, D. Dearei, 
D. bigibbum, D. x chrysotoxum, D. infundibulum, D. X rhodostoma, D. 
Jerdonianum, D. thyrsifloram, D. secundum, D. Devonianum. The 
Philippine Bulbophyllum saurocephalum was represented by three fine 
examples, each bearing numerous racemes, other species in flower being B. 
leopardinum, the Mauritian B. variegatum, B. Lobbii, and B. barbigerum. 
The remarkable Megaclinium triste was also in flower, and a plant of 
Trias picta was pointed out as being remarkable for its leaves having a sheen 
-of peacock blue when seen in the shade. ae 
Numerous rare Epidendrums were pointed out, among those in flower 
-being the rare E. Matthewsii of the Nanodes group, E. virens, E. chloroleu-
