Gentiana (Chondrophylla) pseudo-humilis Makino, sp. nov. 



Biennial, attaining about 5 cm. in height in flower, ipiite glabrous. 

 Roots slender, narrow, filiform, ramose. Stem erect, pauci- to subnumerous- 

 ramose, fleshy, nearly immersed among leaves, with short nodes; branches 

 uniflorous. Leaves closely placed, carnosulate, green, narrowly pellucid- 

 membranaceous on the margin, which is scabrous in lower leaves, sharply 

 carinate dorsally often with scabrous edge, connato-vaginate at the base, 

 trinerved, with loosely anatomosing veinlets above ; lower leaves orbiculate 

 or subspathulato -orbiculate or elliptical and patulose but obovato-spathulate 

 or oblong in ascendant ones, cuspidate, 6-13 mm. long, 2-7 mm. wide, 

 basal ones rosulate ; superior leaves adpressed, 5-9 mm. long, subulato- 

 lanceolate, or subulato-linear, cuspidato-acute, conduplicate. Flower sessile 

 or shortly pedicellate, 13-14 mm. long. Calyx tubuloso campanulate, virides- 

 cent, 5-carinato-angular, narrowed below, about 8 mm. long, l.j-nerved below 

 and loosely anastomosing veined above, narrowly pellucid-membranaceous 

 in valleys ; teeth erect, adpressed, slightly shorter than one-half as long 

 as the tube, deltoid-subulate, acuminato-acute, carinate on the back, pellucid- 

 margined, short and truncate in the edge between teeth. Corolla 1J as 

 long as calyx, tubuloso-infundibuliform, narrowed below, virido-crerules- 

 cent above ; limb much shorter than the tube, broadly deltoide-ovate or 

 ovato-orbiculate, cuspidato-acute, entire ; plaits thinly membranaceous, about 

 i as long as the limb, lato-deltoid, 2-fid, irregularly pauci- or pluri-denticu- 

 late above. Stamens included ; filament subulato-filiform ; anther elliptical

 calyx-teeth, ovate corolla-lobes, and lato-rounded and subentire or dentate 

 plaits ; possibly a variety of the latter species.
