28051) shows both fleshy stems, similar to those of the 
type, and narrowly cylindric stems. 
The Costa Rican Ponera albida, of which we have 
seen a record of the type from the Reichenbach Herbar¬ 
ium, appears to be a slender-stemmed plant of exactly 
the same form as much of the Panamanian material of 
S. Behrii and seems to differ from the white-flowered 
Ponera Behrii only in having “ovate” instead of oblong 
sepals. 
The Guatemalan Scaphyglottis guatemalensis, of 
which we have seen a photograph, a drawing and a flow¬ 
er from the type, is typically a tall, slender-stemmed 
plant with flowers closely similar to those of Ponera 
Behrii and P. albida. 
Scaphyglottis paudflora from Costa Rica, as repre¬ 
sented by a drawing and floral analysis made under the 
supervision of Dr. Schlechter, appears to be inseparable 
from the Scaphyglottis guatemalensis form of the species. 
Judging from a photograph and a flower of the type 
number of Scaphyglottis Sanctae Martae , supplemented 
by a floral analysis made under the supervision of Dr. 
Schlechter, it appears certain that this concept should 
be reduced to S. Behrii. Contrary to Schlechter’s com¬ 
ments, the flower possesses the conspicuously stalked 
ovary which is characteristic of S.guatemalensis (and of 
S. Behrii) together with closely similar flower-parts. The 
only discrepancy between these concepts appears to be 
in the width of the leaves which are broader in S.Sanctae 
Martae than in most of the forms of S. Behrii. 
The Costa Rican Scaphyglottis Bradeorum , of which 
we have specimens and a flower from the type collection, 
is apparently synonymous with S. Behrii. It is a slender- 
stemmed plant with leaves often quite as narrow as those 
attributed to S.guatemalensis and with flowers closely 
similar to those of that concept.
