ever, he mentioned three species under it with full references. Those three 

 species are Pseudosasa japonica, P. spiculosa, and P. Owatarii. Meantime, 

 he meant that Pseudosasa is such a genus of bamboo with mo nopodial well- 

 branched culms provided with non-prominent nodes, the inflorescence 

 lateral to the branches of the upper part of the culms. Of these I heard 

 myself from him in his house et Shibuya where he was living soon after 

 the publication of his Pseudosasa. Apparently, he had mixed two kind 

 of bamboo, one with three stamens and the other with six stamens. In 

 his sense I have given the first generic diagnosis of Pseudosasa in the Jour- 

 nal of the Arnold Arboretum, but I excluded Sasa purpurascens Camus 

 (S. spiculosa Makino & Shibata) from Pseudosasa as its flower has six 

 stamens and neither the sheath nor the leaves have oral setae. It was my 

 error that I joined Bainbusa variegata Siebold and Bambusa dislicha 

 Mitford though they have equalty smooth white wavy oral setaa like 

 Pseudosasa japonica and P. Owatarii. These two bamboos should be 

 classed under Pleioblastus as Dr. Making and I did later {Pleioblastvs 

 distichus Nakai in Rika Kyoiku XV no. 6, p. 69, 1932 ; P. variegatus 

 Makino, Journal Jap. Bot. Ill p. 23, 1926). In 192S, Dr. Makino gave 

 a new diagnosis of Pseudosasa in his Journal of Japanese Botany V no. 4 

 p. 15. This time, he mixed five different types. The first is Arundinaria- 

 kurilen sis-type, the second Arund.inaria-japonica-type, the third Sasa- 

 spiculosa -type, the fourth Sasa- Hisauchii -type, the fifth Sasa-paniculata- 

 type. Among the seven species with one variety and one form enumer- 

 ated by him under this new Pseudosasa, Pseudosasa kurilensis Makino 

 and P. Uchidai Makino belong to the first type and which belong really 

 to Sasa Sect. Macrochlamys Nakai ; Pseudosasa kurilensis var. ncbulosa 

 Makino and P. Togashiana Makino belong to the fifth type and should 

 be classed under Sasa. Sect. Eusasa Nakai ; Pseudosasa japonica Makino 

 and P. Owatarii Makino belong to the second type or the real Pseudosasa ; 

 Pseudosasa spiculosa Makino and its forma angustior belong to the third 

 type or the genus Sasamorpha Nakai; Pseudosasa Hisauchii Making 

 belongs to the fourth type or is Sasaclla Hisauchii Makino, Journ. Jap. 

 Bot. VI. 15 (1929). These five types are distinguished as mentioned 

 below.
