Aster (Heteropappns) leptocladus Makino sp. nov. 



Perennial. Stem erect, terete, striate, nearly glabrous, branched above ; 

 branches very slender, virgate, diffusely spreading, terete, hard, striate, 

 glabrous, leafy, terminating each with the very loose and large corymb, the 

 longest one reaching about 80cm in length including the peduncles. Leaves 

 sparse on stem, Tather dense, linear-lanceolate, very gradually attenuated 

 into the long slender and narrowly winged petiole which is somewhat 

 dilated at the base, 5-15 sometimes 20mm broad, 10-1 6cm long 

 including the petiole, glabrous, ciliated or scabrous-ciliated on the 

 margins, remotely dentate with sub-mucronato-obtuse or sometimes acute 

 teeth, but superior ones very scantly repand-dentate or much obscure, sub- 

 acute with a callose tip at the apex, rather thickish, sub-triplinerved, veins 

 loose and running upwards, the inferior ones already withering in flower- 

 ing time ; leaves on branches much smaller than those of the main stem, 

 erect-patent, oblanceolate or spathulate-linear, narrowed towards the base, 

 scabrous-ciliated, callose-acute at the apex, rather thickish, largest one about 

 ►4Jcm long. Peduncles very slenderly elongate, much loosely arranged, 

 usually curved upwards, striate, glabrous, bracteate ; bracts sparse throughout 

 the peduncle, linear, numerous, gradually decreasing in size up the peduncle and 

 those close to the base of the involucre measuring about 3 J-6mui. in length. 

 Head about 3cm in diameter, solitary at the top of each peduncle. Receptacle 

 slightly convex, foveolate. Involucre spreading, broadly campanulate, 

 about 1J-1 Jem in diameter, few-serial ; involucrahbracts subulate-lanceolate, 

 sometimes ovate-lanceolate, sub-unequal in length, 4-7mm long, gradually 

 attenuated above and very sharply ' acuminate at the tip, herbaceous, thicker
