Mr. Shibata read a paper on the "Flower-buds of Tecoma grandiflora 

 and Nicandra phy sal aides." Dr. Treub found, in 1889, that the young 

 flower-bud of Spathodea campanidata, a plant belonging to Bignoniaceas, 

 is filled with watery liquid within' the calyx for protecction of the inner-bud. 

 After that the similar things were observed in several other plants by Haber- 

 andt, Kraus, and others, and such a calyx was generally known as 

 " water-calyx." Recently Kooders' paper describing all the known plants having 

 the water-calyx was published. Thirteen species of plants of the kind are 

 noted there, all of them belonging to tropical region. Mr. Shibata found 

 that Tecoma grandiflora, common in our garden, is to be counted in this 

 class of plant. Chemical nature of the fluid and the anatomical structure 

 of the glandular hairs together with some discussion on the function of the 

 gland, were given. He made some remarks on Nicandra physaloides which 

 is described in Kooders' paper. 



Mr. C. Owatari made some remarks on the " Teaching of Systematic 

 Botany in Middle and Normal Schools." He recommended to adapt Engler 

 and PranfFs s} T stem in the place of Bentham and Hooker's which is still 

 used in many schools. 



Mr. T. Makino gave some remarks on the " Study of the Japanese 

 Flora." After making the historical sketches, the present state of things 

 was stated. He emphasized the incompleteness of the study of the cryptomaic 

 flora and expressed nis hope to fill up the gap soon. 



Mr. H. Shirasawa gave a description on "A New Species of Tilia 

 from Kiushu." The plant grows on the mountain region of the island of 

 Kiushu. It is named Tilia hiushiana Makino et Shirasawa. Figures and
