punctata from the Madrid Herbarium shows that it rep- 
resents a true Maxillaria of the caulescent many-leaved 
type entirely destitute of pseudobulbs and that it should 
be transferred to the latter genus. However, the epithet 
punctata is preoccupied by Maaillaria punctata odd. 
and another name is thus necessitated. 
Fortunately, Mernandezia punctata seems to be refer- 
able to M. arbuscula, which was noted by Reichenbach 
as ‘‘Fernandezia del Peru.’’ The only differences are 
that in Maedllaria arbuscula the leaves were described as 
up to 7.6 cm. long and 9 mm. wide (those of Mernan- 
dexia punctata being up to 6.4 em. long and 6 mm. wide) 
and the callus on the lip is noted as linear, depressed and 
retuse, whereas that of Mernandezia punctata is oblong 
and much more conspicuous above with a rounded apex.

A series of recent collections in the Ames Herbarium 
from Colombia, Peru and Bolivia agree well with an ex- 
cellent photograph from the Lindley Herbarium of the 
type of Ornithidium giganteum which bears a floral anal- 
ysis and with the description. 
A perusal of this evidence indicates that O. gi@anteum 
seems to be merely a variety of O. aureum, as typified 
by Poeppig and Endlicher in Nov. Gen. ac Sp. 1 (1836) 
57, t. 96 and described by Cogniaux in Martius FI. Bras. 
3, pt. 6 (1904) 89. It differs only in having the lip ob- 
scurely 3-lobed with the lobules consistently more or less 
erose-denticulate. The apical portion seems to vary from 
being relatively small to being subequal to the lateral 
lobules.
