Sent from Santa Fé de Veraguas, by the late Mr. Skinner, to 
W. Wilson Saunders, Esq., being one of the novelties obtained 
by the efforts made to obtain materials for the ‘ Refugium.’ 
The species stands near Ponera stellata, Rchb. f. (Scaphyglottis 
stellata, Lindl.) Yet that has quite linear leaves, very short side 
lobes to the lip, and an acute middle lobe. The two horns of the 
column would appear to be strictly divaricate. We have ex- 
amined once more the Lindleyan type we possess, and in 
October, at Kew, saw the type of the Lindleyan herbarium. 
Roots thin, filiform, hanging down, with very small granu- 
lations on the surface. Pseudobulbs standing close together, sti- 
pitate, consisting of eight or nine joints; the principal part, 
forming the greater portion of the bulb, is ligulate-fusiform, com- 
pressed, obtuse-angled, elliptical in cross-section, bearing two 
linear-ligulate bilobed leaves, and between them the terminal 
unflorescence arising from the axil of one of those leaves and 
forming anew axis, so that one may find three bulbs standing 
one over the other. There are sheaths on the bulbs, forming a 
series of distichous scales under the larger joint: these, when 
young, have articulated acute lamine, which fall away very early. 
A young shoot consists of a number of such distichous sheaths 
and of leaves. ‘The inflorescence is a short umbel-hke or sub-
