NEW OR NOTEWORTHY ORCHIDS 
Epidendrum diurnum (Jacq.) Reichb. f. and E. virens 
Lindl. are sometimes regarded as distinct species. Lindley’s 
specimens of Epidendrum virens resemble so closely tbe figure 
of Limodorum diurnum Jacq. that we are justified in agreeing 
with Cogniaux that they constitute a single species. Reicb- 
enbacb in proposing tbe combination Epidendrum diurnum 
cited E. virens Lindl. as a synonym.

Epidendrum Kienastii Reichb. f. in Gard. Cbron. ser. 
3, 2 (1887) 126. 
This rare Mexican species wbicb is known to me only 
tbrougb tbe type specimen in Reicbenbacb’s Herbarium and 
a specimen in tbe Kew Herbarium received from Kienast in 
1898, presumably from tbe type plant cultivated in Zurich, 
is not included in Scblecbter’s Kritiscbe Aufzablung der 
bisber aus Zentral-Amerika bekanntgewordenen Orchida- 
ceen. It is a very distinct species, quite unlike any other 
Mexican Epidendrum that I have seen. The sepals and 
petals are about 2 cm. long, the former oblong and acute, 
the latter spatulate. The labellum is about 2 cm. long, 
somewhat less than 1 cm. wide across the large terminal lobe. 
The lateral lobes are smaller than the middle one and are 
spatulate in outline. On the disc between the lateral lobes 
there is a forcipate callus. The flowers are described as being 
rose-color with a white labellum.

Epidendrum laterale Rolfe in Orch. Rev. 20 (1912) 
280, 319, nomen tantum; 28 (1920) 160. 
In Schedulae Orchidianae 3 (1923) 19, I referred this 
species to synonymy under E. Rousseauae Schltr. It seemed 
to me that the only substantial difference between Rolfe’s 
type specimen and the material of E. Rousseauae that I had 
been able to study was one of size, E. laterale having larger 
flowers and more robust vegetative parts. Rolfe described 
E. laterale as follows: “ It bears tufts of cylindrical pseudo-
