298 THE ORCHID REVIEW. [OcTOBER, I9Io. 
(O.R., viii. pp. 335, 336), remarking: “*A comparison with Mr. Lehmann’s 
drawing shows several marked differences. The petals are much broader 
and less attenuated, while the front lobe of the lip'is ovate-elliptical ‘rather 
than linear, but whether this is due to variation or to some other cause is 
not yet apparent.’’ The original specimen was not available for com- 
parison. Sir Trevor’s plant was soon afterwards figured in the Botanical 
Magazine (t. 7805), as Trevoria Chloris. 
Since then the Lehmann Herbarium has been acquired for Kew, and it 
contains a Colombian specimen authenticated by Lehmann himself as 
Trevoria Chloris. This consists of two leaves and part of the inflorescence 
bearing a single fruit. On a second sheet were unlabelled flowering and 
fruiting racemes which probably belong to the original ticket, for the flower 
on examination proves identical with Lehmann’s figure. No trace of the 
Ecuadorian plant with the long raceme of fruits only has been found. 
In September, 1903, three flowers were sent to Kew by Mr. J. O’Brien, 
with the record that they were ‘from a plant of Trevoria sent over by 
Lehmann, presumably-of T. Chloris,”. and’ they proved identical with the 
one in Sir Trevor’s collection. 
On September 25th, 1908, a Botanical Certificate was given by the 
R.H.S. to a plant of ‘‘ Trevoria Chloris” from the collection of E. Ashworth, 
Esq., Harefield Hall, Wilmslow (O.R., xiv. p. 310), which I had not the 
pleasure of seeing, but the plant has now flowered again, producing two 
racemes, which have been kindly sent by Mr. Ashworth, together with the 
photograph here reproduced. This is also identical with the one in Sir 
Trevor’s collection, and it is now evident that there is a third species,ewhich 
may be called T. Lehmanni, after its discoverer. The original species, still 
only known from fruiting specimens, may be called T. ecuadoriensis. The 
following are the references to the three species :-— 
T. ECUADORIENSIS, Rolfe. T.sp.,-Lehm., in. Gard. Chron., 1897, i. p- 
346; Orch. Rev., v. p. 2033; vili. p. 335.—Ecuador. 
T. CHLoris, Lehm., in Gard. Chron., 1897, i. p. 345, Suppl. fig. 128; 
Orch. Rev., v. p. 203; viii. p. 335 (in part).—Colombia. 
T. LEHMANNI, Rolfe. T. Chloris, Rolfe in Orch. Rev., viii. p. 335 (in 
part); Bot. Mag., t. 7805 (non Lehm.).—Colombia. 
As regards T. ecuadoriensis nothing further can be said until materials 
are available. T. Chloris now rests upon Lehmann’s original description 
and figure, with the corresponding dried specimens above mentioned. It 
differs from the following species in having longer and much narrower 
attenuate petals, and a linear front lobe to the lip. T. Lehmanni is fully 
described in the Botanical Magazine under the name of T. Chloris. Its 
general appearance is very well shown in the annexed figure, and we may * 
add that the flowers measure over an inch long, and are pale green in
