482. NEOTTEJE—SPIRANTHIDJE. 
Pd 
Scape about a foot high. Flowers green, small, with a white labellum 
stained with yellow in the middle. 
9. PELEÉx1A corymbosa. 
P. foliis. . . . ., scapo pubescente squamis acuminatis distanter vaginato, 
corymbo capitato, bracteis ovatis acuminatis ovario elongato brevioribus, 
sepalis petalisque linearibus acutis basi angustatis lateralibus in cornu 
ovarii dimidià brevius decurrentibus, labello glabro columna arcte 
agglutinato ; basi lineari sursüm dilatato cucullato apice ovato crispo.

Hab. in Peruvia, Pavon. (hab. s. sp. comm. cel. Lambert.) 
I have only seen a head of flowers and about 4 inches of the upper part 
of the scape of this plant, which is strikingly different from Neottece in 
general, in its half corymbose half capitate inflorescence. A second ex- 
amination, with additional experience in the manner of dissecting the 
dried remains of these delicate flowers, has taught me that the labellum is 
merely glued to the column in this plant and not organically united with 
it. There is therefore no character to divide it from Pelexia. 
3. Perex ? laxa. 
P. *labéllo basi atteuuata adnato, canaliculato, lanceolato, acuto, sepala 
zquante; sepalis inferioribus basi saccata coalitis, superioribus puberulis; 
bracteis flore brevioribus ; spica secunda, laxa ; foliis longe petiolatis, 
ellipticis, acutis.

4. PeLexia setacea. 
P. foliis ovalibus petiolis duplo brevioribus, spicà multiflora, bracteis 
lineari-lanceolatis setaceo-acuminatis ovario longioribus, sepalis lineari- 
lanceolatis in apicem setaceum elongatum productis, labello lanceolato 
fimbriato sepalis breviore, cornu filiformi acuminato semilibero sepalis 
breviore, rostello corneo setaceo persistente.

A leaf before me is 6 inches long, nine nerved, with a petiole a foot long. 
The scape is slightly downy, 1 to 2 feet high with a long loose spike. 
The lateral sepals are more than 2 inches long, and drawn into a very fine 
bristle-like point. The Neottia calcarata of the Botanical Magazine, said 
to be from Jamaica, is certainly this Brasilian plant, and is very different 
from that of Swartz. 
5. Perexia domingensis. 
P. foliis ellipticis petiolis brevioribus, spicá pauciflorà, bracteis linearibus 
lanceolatis florum longitudine, sepalis petalisque lineari-lanceolatis
