120 Nasu: Costa RICAN ORCHIDS 
rather abruptly contracted above into a laterally compressed and 
keeled apex, more or less pubescent on the back with black-brown 
deciduous hairs, about 5-nerved ; dorsal sepal 5-6 mm. long, and 
about 2 mm. wide, the compressed apex much less prominent: 
petals oblong-linear, somewhat dilated at the rounded and apicu- 
late apex, 6-7 mm. long, 1.5—2 mm. wide: lip nearly campanu- 
late, completely surrounding the column so that its margins meet, 
about 7-8 mm. long, when spread out 10-12 mm. wide at the 
truncate and sparingly ciliate apex and 5-6 mm. wide at the base, 
a 2-ridged crest just below the middle, the two appendages near 
the base of the lip oblong, papillate, 1.5—-2 mm. long and about 
I mm. wide: column 7-8 mm. long, 4-toothed at the broadened 
apex. 
On the lower horizontal branch of a tree bordering the Agua 
Caliente, in the humid region, upon the Finca Navarro, mo. 692. 
CATASETUM MACULATUM Kunth, Syn. Pl. Aequin. 
Es 248.1839 
Cultivated at San José, xo. 352. Another species which Mr. 
Maxon secured from Mr. Biolley, who secured it at San Mateo, on 
the Pacific coast. It flowered with us first on November 23 of 
last year. This material very closely agrees with the description 
of Kunth, also with the details of the figure published (H. B. K. 
Nov. Gen. & Sp. 7: p/. 630). The parts are not so greenas called 
for in that description, and this perhaps accounts for Mr. Maxon 
receiving the plant under the name of var. /uteopurpurata Cogn., 
a name, however, of which I can find no record of publication. 
Mr. Percy Wilson, who visited Honduras in 1903 in the interests 
of the New York Botanical Garden, also obtained living material 
of the same species which has flowered at the Garden. 
Catesetum maculatum was found first near Turbaco, Colombia, 
at an altitude of about 324 m. I cannot think, however, that 
the C. maculatum of Bateman (Orch. Mex. & Guat. f/. 2) is the 
same thing, for the setae of the column are described and figured 
as very short, quite different from the very long ones in the true 
C. maculatum Kunth. The C. maculatum of Lindley (Bot. Reg. 26: 
pl. 62. 1840) seems to be different also; the color of the flowers 
is quite different and the petals are etre: while in the plants from 
Costa Rica and Honduras these parts are decidedly serrated, thus 
agreeing with the original description of Kunth.
