NEW OR NOTEWORTHY ORCHIDS 
Aphyllorchis halconensis Ames sp. nov. Herba 
aphylla, vaginis amplis instructa. Racemus laxiflorus, 
bracleis flores sub tendentibus elongatis, anguste lanceolatis, 
ovarium aequantibus vel superantibus. Ovarium glandu- 
losum. Sepala lateralia oblongo-lanceolata, acuta, prope 
apicem plus minusve carinata, extus sparse glandulosa. 
Sepalum dorsale subsimile, valde concavum, extus sparse 
glandulosum. Petala oblongo-lanceolata, leviter curvata, 
extus per medium leviter carinata, acuta. Labellum tri- 
lobatum, sepala lateralia vix aequans; lobis lateralibus late 
triangularibus, quam lobo medio multo minoribus; lobo 
medio lanceolato, subtus valde carinato, margine irregulariter 
crenulalo. Discus inter lobos laterales incrassatus, prope 
basim lobi medii bicarinatus, carinis plus minusve crenulatis. 
Columna elongata, curvata, superne dilatata. 
A leafless herb 11.5 dm. tall, stems clothed at intervals 
with loose tubular sheaths, those near the base of the plant 
closer together than those near the summit. Sheaths .5-3 
cm. long, the upper ones longest about 10 cm. apart, the 
lowermost ones shortest about 1.5 cm. apart. Raceme 10 cm. 
long, loosely dowered. Floral bracts 1.5-2 cm. long, 3 mm. 
wide, linear-lanceolate, equaling or slightly exceeding the 
pedicellate ovary, spreading or slightly deflexed. Pedicel 
with the ovary up to 23 mm. long, densely glandular- 
pubescent, oblicpiely ascending. Lateral sepals about 1.3 
cm. long, 3.5 mm. wide, oblong-lanceolate, acute, becoming 
strongly carinate on the outer surface toward the tip, 
sparsely glandulose. Dorsal sepal 1.5 cm. long, strongly 
concave, arching forward over the slender column. Petals 
1.5 cm. long, about 3.5 mm. wide above the middle, more 
delicate in texture than the sepals, oblong-lanceolate, acute, 
lightly carinate on the outer surface, with one central 
branching nerve. Labellum 1.3 cm. long, unequally 3-lobed; 
lateral lobes basal, 2.5 mm. long to the sinus formed with 
the middle lobe, triangular, subacute; middle lobe 1 cm. 
long, about 5 mm. wide below the middle, lanceolate, deeply 
carinate at the cymbiform tip. Disc thickened between the 
lateral lobes, bicarinate at the base of the middle lobe, the
