Aster tenuipes Makino sp. nov. 



Stem slender, terete, hard, obscurely striated, pubescent, leafy, pro- 

 ducing many peduncles above so as to imitate a loose and oblong panicle. 

 Leaves sparse, loosely approximate, spreading but sometimes slightly reflexed, 

 linear-oblanceolate, subsessile, gradually attenuated towards both ends, acute 

 at the apex, remotely and scantly serrate above with acute teeth, nearly 

 entire in the superior ones, ciliated along the margins and pubescent on the 

 midrib on both surfaces, 3Jh5Jchi long, 4-8mm broad, rather thin, sub- 

 t rip] i nerved; midrib slender, slightly elevated, distinct, and two lateral nerves 

 weak, flexuous, fine ; veins oblique, fine, very loose ; veinlets very fine and 

 dense, but invisible superficially. One of the peduncles terminal and others 

 lateral, the latter issuing from the leaf-axils in the upper portion of the 

 stem, about l£-6jcm long, slender, strict, spreading, pubescent, bracteate 

 throughout, often branching into a few short pedicels above; bracts small, 

 rather densely growing, sparse, linear, sessile, narrowed towards the base, 

 acute at the apex, thinly ciliate and subpubescent along the midrib, 

 inferior ones larger and about 2cm long, superior ones gradually reduced 

 in size and at last passing into the involucral-bracts. Involucre cam- 

 panulato-cyathiform, obtuse at the base, 4-5rnm in diameter; involucral- 

 bracts small, imbricated in few-series, unequal, smaller and shorter in the 

 outer ones, spathulate-oblong, largest ones about 5mm long, l|mm broad, 

 glabrous, manifestly ciliated along subscarious margins, thicker towards the 

 median part and I -nerved, rather rigidly herbaceous, green towards the 

 tip, the tip mostly obtuse and scarious, but the outer ones somewhat 

 thicker and often acutish. Heads l§-2Jcm in diameter. Receptacle 

 flat and foveolate. Ray-flowers 9-13 in number, patent. Corolla: 

 ligule oblong-strap-shaped, 6J-8^mm long, 2- nearly 3mm wide, bluish- 

 lilac, rounded-obtuse and minutely tridenticulate at the apex, 5-G-nerved ;
