Nauenia spectabilis, Klotzscli in Otto et Dietr. Allg. Gartz, 1853, 193.
A very little-known genus, of which only two species
have been discovered, the present and L. bicolor, on which
the genus was founded by Lindley (Bot. Reg. 1844, t. 50),
and which is a native of Guatemala, The present is by
very much the handsomer species of the two, and is re-
markable for the delicate colouring of the perianth, which
in L. bicolor is of a greenish-yellow hue, and not speckled
in the lip. The two species differ widely, this having a
much longer claw, a horn, concave in front, between the
lateral lobes, and a stipitate mid-lobe; whilst that of L.
bicolor has a very short claw, a beard between the lateral
lobes, and an almost sessile mid-lobe.
Lindley, who named the genus, called it by one of the
names of Helen (Lacama), because of its beauty; a com-
pliment which the Botanical Register's representative of
L. bicolor does not at all merit ; he adds, however, that it
may also be derived from Xa/aç, a cleft, in allusion to the
divisions of the lip.
L. spectabilis flowered at Kew in the spring of this year ;
