336 THE ORCHID REVIEW. 
metres above the sea, and produces flower-spikes of from twenty to thirty 
flowers, the size and character being as yet unknown, while the Colombian 
one inhabits a region from 1500 to 1700 metres above the sea (as far as 
observed), and bears racemes of only three to five—commonly, only three 
flowers. 
“As a genus, Trevoria is very characteristic and distinct. Its nearest 
neighbours are Coryanthes, Schlimia, Stanhopea, and Gorgoglossum, but 
it is distinguishable at first sight from either of them. Trevoria chloris 
produces large, fleshy, wholly green flowers, placed on the drooping spike in 
the manner of the buckets of a dredger chain. The narrow disc of the lip 
and the thick, coriaceous process at its base are the only different coloured 
organs in the flower ; they are pure white. Both from a morphological, as 
also from a physiological, point of view this genus is very novel and inter- 
esting. The position of the column and lip, standing straight upright in an 
urceolate manner, the thick, fleshy process at the base of the lip being of 
exactly the same length as the column, and standing parallel and closely 
adpressed to that organ, the peculiar shape and insertion of the stigma, 
and several other items, are wholly novel, and the arrangement of them to 
each other may set at nought some of the pet views of modern hypercritical 
speculators with respect to the aid of insects in the fertilisation of Orchids, 
or give rise to quite new conceptions. 
‘I have named this genus of Orchidacee in honour and commemoration 
of Sir Trevor Lawrence, one of the most enthusiastic Orchidists that ever 
lived. Trevoria has to answer our purpose ; Lawrencea and Lawrencella 
being already in existence in Composite and Malvacez respectively. May 
Sir Trevor’s love of Orchids perdure sempervirent as Chloris, the goddess of 
flowers.”’ 
A comparison with Mr. Lehmann’s drawing shows several marked differ- 
ences. 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 saccate base of 
the lip and the large crest tightly appressed to the column are remarkable, 
but there is nothing in the flower to suggest new views about the aid of 
insects in fertilisation, a matter about which we know surprisingly little 
in connection with Andine Orchids, and it would be interesting if Mr. 
Lehmann would utilize some of his opportunities by observations in this di- 
rection. Whether the Ecuador plant belongs to the same genus perhaps 
remains to be proved, considering that the flowers are not yet known, and 
it is to be hoped that more plants of it will soon be obtained. The dis- 
covery of such a striking species as the one under notice is a sure indication 
that our knowledge of Andine Orchids is still far from complete.
