NOTES ON PHILIPPINE ORCHIDS, III. 53 
broken up into a delicate spreading fringe the filaments of which are about 5 
mm long. 
Lindley’s type specimen, for an excellent sketch of which I am indebted to 
Doctor Prain, is perhaps stouter than my plants, but in other respects matches 
them perfectly. The labellum of D. scopa is well illustrated in Lindley’s her- 
barium by a colored drawing. In outline and in general aspect this drawing 
agrees very well with the labellum of the plants collected by Mr. Lyon. 
Dendrobium scopa is referred to in J. J. Smith’s “Die Orchideen von Jaya” 
as probably related to D. comatwm Lindl. From the specimens at hand it would 
seem to be more nearly allied to D. angulatum in the form of the lip, but differs 
from that species in detail.

276. SARCOPODIUM Lindl. 
In the “Orchid Review” for August, 1910 (18: 237) Mr. R. A. Rolfe 
gives a list of twenty-one species, usually referred to Dendrobium, which 
he regards as constituents of a distinct genus, namely Sarcopodium. This 
genus was originally proposed by Lindley for the inclusion of a small 
group of species which Reichenbach f. referred to Bulbophyllum. At 
present only three Philippine species of Sarcopodiwm are known. All 
of these have recently been described. S. acuminatum Krinzl. was the 
first to be discovered, S. Lyonii Rolfe (8S. acuminatum var. Lyonit 
Kranzl.) the second, and S. stella silvae Krinzl. & Loher, a species which 
I have not seen, the third. 
In its brief history Sarcopodium Lyonw has accumulated an interesting 
synonymy as follows: 
Sarcopodium Lyonii R. A. Rolfe in Orch. Rev. 18: 240. 
Dendrobium Lyonii Ames Orch, 2: 177. 
D. acuminatum Krinzl. Orchis 2: 73, not Rolfe. 
Sarcopodium acuminatum var. Lyonit Kriinzl. in Fedde Rep. 7: 40. 
In view of Doctor Krinzlin’s treatment of S. Lyonii, Mr. Rolfe’s opinion in 
the “Orchid Review” is of interest. He says S. Lyonii is allied to S. acwmin- 
atum, but has larger rosy-carmine flowers with a darker lip. “It has been con- 
fused with the preceding,’ and I believe includes all the plants which have been 
recently exhibited under the name D. acuminatum, also the figure in Gard.

Phreatia prorepens Reichb. f. Otia Bot. Hamb. (1878) 54. 
Up to the present I had seen only the material in the Gray Herbarium 
identified by Reichenbach and the specimens collected by Merrill on Mount 
Halcon. The collection under consideration was made by McGregor and is of 
unusual interest as it is composed of numerous specimens which exhibit a wide 
range of variation, some of the scapes approximating 2 dm in length. The 
variation in the leaves is also notable, ranging from the ligulate form char-
