NEW OR NOTEWORTHY ORCHIDS 
Camaridium costaricense Schltr. in Fedde Repert. 3 
(1907) 250. C.Tonduzii Sc/j/Zr. in Fedde Repert. 8 (1910) 571. 
Apparently these two species were described from the 
same collection, and the published descriptions are nearly 
identical. 
Ornithidium Alfaroi A. & S. sp. nov. Rhizoma 
repens, arcuatum, bracteis distichis dense imbricantibus 
omnino vestitum. Pseudobulbi adscendentes cylindracei 
vel suborbiculares, valde complanati, monophylli. Folium 
ovato-ellipticum vel oblongum, in apice rotundatum. Flores 
parvi. Sepala lateralia usque supra medium connata. 
Sepalum dorsale elliptico-oblongum. Petala sepalo dor- 
sali persimilia sed minora. Labellum sepalorum sacco in- 
clusum, trilobatum, callo transverso ornatum. 
Plant creeping. Rhizome stout, arcuate or flexuous, 
densely invested by distichous imbricating sheaths, 3-5 mm. 
in diameter when naked, up to 1 cm. across when concealed 
by sheaths. Pseudobulbs monophyllous, complanate, cylin- 
dric to suborbicular, 1.5-4.5 cm. high, 1.3-1.9 cm. across, 
striate-sulcate or rugose in the dried specimen, 1-4 cm. apart 
on the rhizome, the lower part invested by sheaths which 
waste into fibers in anthesis. Leaf ovate-elliptic to oblong 
or ligulate; lamina 4.05-17.5 cm. long, 1.7-2.55 cm. wide in 
the middle, rounded and minutely apiculate at the apex, 
abruptly narrowed at the base, chartaceous or subcoriaceous, 
mid-nerve sulcate above and carinate beneath; petiole (if 
present) up to 1 cm. long, channeled-conduplicate. In¬ 
florescences short, clustered in the axils of bracts on the 
rhizome. Peduncle abbreviated, about 2 mm. long, entirely 
concealed by several sheaths which are inflated, distichous 
and imbricating. Flowers small. Lateral sepals connate 
to a point beyond the middle forming a short saccate 
spur at the base, 9-9.5 mm. long; free portions obliquely 
ovate, acute or somewhat obtuse, up to 3.7 mm. long, 
inner margins overlapping. Dorsal sepal elliptic-oblong, 
8 mm. long, 3 mm. wide in the middle, acute. Petals very 
similar to the dorsal sepal but markedly smaller, 6.4 mm.
