AN ADDITION TO 
THE GENUS HEXADESMIA 
BY 
OAKES AMES 
THE NEW SPECIES of Hexadesmia described below 
might readily be mistaken for a tall, slender form of 17. 
crurigera Lindl., but in the texture and color of the 
flowers, and in the outline of the very different labellum 
it is quite distinct. 
Hexadesmia hondurensis Ames sp. nov. In 
habitu Hi. crurigerae Lindl. similitudinem gerit, sed 
labelli lobis et magnitudine differt. Caules caespitosi, 
valde elongati, diphylli. Folia anguste linearia. Pedun- 
culus quam folia brevior. Racemus plus minusve septem- 
florus. Sepala lateralia mentum rotundatum formantia, 
ovato-lanceolata, acuta, extus per medium leviter cari- 
nata. Sepalum dorsale oblongo-lanceolatum, concavius- 
culum. Petala oblonga, apice abrupte rotundata. Label- 
lum subpanduratum, apice valde bilobatum, prope basim 
bicallosum. Columna in pedem producta. 
Stems densely caespitose, erect, 12-15 cm. tall, min- 
utely pseudobulbous at the base, very slender and many- 
sheathed for about 6 em. then abruptly thickened to form 
an elongated secondary pseudobulb which is 8-9 cm. long, 
about 5 mm. in diameter when dry, subtended by several 
imbricating truncate sheaths and diphyllous at the apex.
