120 Ames Three New Orchid &pecies. 



" An interesting addition to the small section Bolbodium, allied to D. 

 pumilum Eoxb., but far larger in all its parts, and the pseudobulbs dis 

 tinctly quadrangular upwards, as in the Burmese D. quadrangulare Parish, 

 which, however, has smaller flowers and a proportionately shorter mentum. 

 The remaining species is the Philippine D. hymenanthum Rchb. f." Type 

 in herbarium of the Ames Botanical Laboratory. 



Epidendrum Pringlei Rolfe. 



" Densely tufted; pseudobulbs ovoid-oblong, 7-10 lines long, 1-2-leaved ; 

 leaves linear-oblong, subobtuse, coriaceous, 2-3 inches long ; scapes slender, 

 erect, 2^-4 inches long, 1-2-flowered ; bracts ovate, apiculate, 1 line long; 

 pedicels 6-8 lines long ; sepals broadly lanceolate, acute, 5 lines long, 

 reflexed ; petals linear-lanceolate, acute, 5 lines long, reflexed ; lip free 

 from column, very shortly stalked, limb dilated into a transversely oblong 

 or suborbicular blade, about 5 lines long by 7 broad, thickened at the base 

 into a two or three-keeled callus from which three slender nerves extend 

 toward the apex ; column 2 lines long, broadly clavate. Mexico, State of 

 Morelos, near Cuernavaca, on tops of mountains, at 8,000 ft. altitude ; C. G. 

 Pringle, May 12, 1898. 



" A species of the Encycimm section, nearly allied to E. haslatum Lindl., 

 but more slender and smaller in all its parts. The sepals and petals are 

 somew r hat fleshy, and appear to have been dusky brown in colour, while the 

 limb of the lip is membranaceous and white. Of known species it can only 

 be compared with the one mentioned, but it is well characterised by its 

 very slender habit." Type in herbarium of the Ames Botanical Laboratory. 



Epidendrum oaxacanum Rolfe. 



" Stems erect, subterete, leafy, 1|-2| ft, high ; leaves oblong, subobtuse, 

 coriaceous, 3-4 inches long, f-1 inch broad ; inflorescences terminal and 

 axillary on the upper part of the stem, somewhat branched, aggregated 

 into a loose head 2^-3 inches long, covered with lanceolate-oblong imbricat 

 ing striate sheaths at the base ; bracts triangular-ovate, acute or acuminate, 

 1^-2 lines long; pedicels 5-7 lines long, slender; dorsal sepal narrowly 

 spatulate-lanceolate, subobtuse, lateral pair rather broader, all more or less 

 convolute, 5-6 lines long; petals narrowly spatulate-linear, subobtuse, 5-6 

 lines long ; lip adnate to the column, limb three-lobed, 5 lines broad ; front 

 lobe ovate-oblong, obtuse, with three prominent erect keels ; side lobes 

 spreading, broadly oblong, obtuse, with about five thickened veins ; lobes 

 about 2 lines long; disc bearing a pair of broadly oblong crests near the 

 base of the side lobes; column clavate, 4 lines long. Mexico; State of 

 Oaxaca, Sierra de San Filipe, at 7,500 ft. altitude ; C. G. Pringle, Nov. 19, 

 1894, n. 5830. 



"An interesting addition to the small section Acropleuranthium, charac 

 terised by having both terminal and axillary inflorescences, of which E. 

 exasperatum Rchb.f. and E. Wallisii Rchb. f. have hitherto been the known 

 representatives. It is very distinct from either and from the dried speci 

 mens appears to have yellowish green flowers." Type in herbarium of the 

 Ames Botanical Laboratory.
