Hab. Prov. SUEUGA : Foot of Mt. Fuji (Junshiro Watanabe ！ 

 July 25, 1916). 



This new species was found and collected by the late J unshiro 

 "Watanabe of Yokohama, and the specimen was sent to me for the 

 determination ； I have named this in honour of the collector. The 

 lay and leaves at the top of the plant are yellow, on account of which 

 this species bears a very peculiar appearance. The stem and leaves 

 are like in Euphorbia dolkini Boiss., but the stem is more slender, 

 leaves more tapering, and terminal leaves, bracts and 2nd 

 bracts are yellow in colour. This species grows in the moun- 

 tain district, while E. Jolkini Boiss. is found always on sea side in 

 Japan. 



Sasa Shimidzuana Makino, nov. sp. 



Khizome repent. Culm erect, about 12 decim. high, ramose above, 

 slender, terete, smooth, fistulöse, about 3-4| mm. across, green and oft- 

 en purpurascent ； nodes somewhat prominent ； branches one to each 

 node, ascendingly erect, closely encircling with sheaths, with the white 

 waxy bloom under the node when young. Leaves about 2 to 5 to- 

 wards the top of branches, palmately arranged ； lanceolate or oblong- 

 lanceolate, acuminate, acutisli to rounded at the base, shortly petiolate, 

 coriacso-chartaceous, scabrous on margin, about 10-28 cm. long, 

 2|-4J cm. broad, green and glabrous above, glaucous and thmly 

 pubescent below beneath, narrowly albo-marginate by the decay in 

 winter ； midrib slender, prominent beneath ； veins 7-10 on each 

 side ； veinlets very fine，y tessellate ； petiole 3-12 mm. long ； ligule 

 depressed-semiorbicular, coriaceous, densely sliort-pubsrulent out- 

 side ； sheath long, closely encircled, finely striate, green, often 

 purpurascent, at first hirsuts-pubescent with depressed hairs but 

 usually then glabrate from the fall of hairs, ciliatsd, coriaceous. 



Nom. Jap. Hakone-suzu (nov . nom.). 



Hab. Prov. SAGAMI : Hakone, near Ashinoju (T. Makino ！ , K. 

 Hisauchi ！). . 



This species is found rarely on the mountain of Hakone, and it 

 has an ally to Sasa nam Maeino, from which it differs by having 

 the pubescent sheath. It is probably a hybrid between Sasi 

 spiculosa Makino and S. Tokugawina Makino. I have named it in 

 memory of Mr. Totaro Shimidzu, member of the Yokohama Botanical 

 Society.
