bracts. Spike elongate-cylindric, loosely many-flowered, 
up to about 26.5 cm. long; rachis densely tomentose. 
Floral bracts ovate-lanceolate, acuminate, tomentose on 
the outer surface, finely ciliate, surpassing the ovary but 
shorter than the flower. Ovary densely tomentose. Flow- 
ers small, ‘‘white with yellow center’’. Sepals tomentose 
on the outer surface, tubular-concave with recurved apex, 
subfleshy. Dorsal sepal lanceolate-elliptic, subacute, 8 
mm. long, about 2.3-2.6 mm. wide, 3-nerved, adnate to 
the column. Lateral sepals connate below into a long 
tube which is about 7 mm. long; free portion obliquely 
oblong-oblanceolate, acute, 4-nerved, about 10.5 mm. 
long and 4mm. wide. Petals linear or oblanceolate-linear, 
very abruptly and obliquely subacute, 1-nerved, about 
8-9 mm. long, with the upper margins slightly irregular. 
Lip uppermost, tubular-involute in natural position with 
recurved-flaring apical portion, long-adnate to the sepal- 
ine tube at the base; free portion when expanded broadly 
spatulate-obovate with the lower part concave and very 
fleshy and the anterior part relatively thin, semiorbicular 
and lobulate, about 8.5 mm. long. Column long, slender, 
about 12 mm. long, retrorsely arcuate and lightly clavate 
above, with its posterior surface long-adnate to the sepal- 
ine tube, tomentose in front in the middle, retuse and 
apiculate at the summit; anther semiovoid, obtuse, 2- 
celled. 
Stenoptera laxiflora is allied to S. peruviana Presl, but 
differs in having much taller stouter stems which are 
leafy, longer looser spikes and larger flowers with dis- 
similar lip.
