j. xv ioo3.] MAKINO.—OBSERV. ON THE FLORA OF JAPAX. 139 



A terrestrial Orchid. Roots slender, flexuous, terete, to- 

 mentose, not dense. Rhizome repent, flexuous, viridescent 

 or whitish, terete, with 3-5-nodes ; the intervals of the pseudo- 

 bulbs short and about 3—14 mm. in length ; pseudo-bulbs erect 

 or more or less inclined, small, ovoid or elongato-ovoid, 

 sometimes angustate, straight or slightly curved, 6— l-J-cm. or 

 rarely 2 cm. long, 2i— 7 cm. across, green, smooth, attaining 

 about 13 in number to a stock, loosely covered with old fibres 

 of sheath at the base and with those of leaves at the top. 

 Leaves long- or short- petiolate, one to a pseudo-bulb, lanceolate, 

 oblong-lanceolate, acuminate, acutely attenuated at the base, 

 entire and crispulate on margin, membranaceous, plicate, green 

 and albo-maculate above, purpurascent beneath, 4-13 cm. long, 

 l-2f;cm. broad ; main nerves 3 and subacutely prominent beneath 

 and impressed above ; veins 2—3 sometimes 5 between the main 

 nerves ; transverse veinlets loose, usually oblique, often curved 

 or flexuous, green along the veinlets and pale between them. 

 Scape erect, aphyllose, slightly or considerably longer than leaves, 

 lateral at the base of the pseudo-bulb, subtnberous (provided 

 with a lateral bud) and sheathing at the base, slender, terete, 

 about 8—39 cm. long, with a few nodes and elongated internodes, 

 glabrous, light purple, sheathing in the basal portion and the 

 middle ; sheath few, membranaceous, purpurascent, the basal 

 one smaller and the upper tubular (the uppermost one If— 3f cm. 

 long), oblique at the mouth, acutish at the apex. Raceme 

 erect, 3-5-flowered, about 2— 10cm. long; rachis flexuous or not 

 so, often slender, often purplish, glabrous, slightly compressed ; 

 bract a little or much more shorter or somewhat longer than 

 tin pedicel, membranaceous, lanceolate, acuminate, 3-6 mm. long, 

 distantly 3— nerved, purpurascent. Flower pedicellate, small, 

 rather loosely or much loosely disposed, usually secund, turned 

 outwards, glabrous. Perianth erect-patent, subpadio-purpuras- 

 cent but yellowish towards the base, entire, 3-nerved. Sepals 

 subequal ; dorsal one free, linear or lato-linear, acute or sub- 

 obtuse at the apex, in 12' mm. long, 1' 2 mm. wide; lateral 

 one-, subequal to the dorsal one, linear or linear-lanceolate, 

 hardly falcate, acute, adherent to the lateral sides of the basal
