Takeda, HL, On some Potentillas from the Far East. (Kew 

 Bull. Mise. Inf. N°. 6. p. 250—256, with text figures. 191 l.j 



An aecount of the various species of Potentilla from Eastern 

 Asia which have been referred to P. fragiformis, Willd.. P. mega- 

 lantha, Takeda is a new species near P. fragiformis: it is a native 

 of Yezo, the Kurile Islands and Saghalien. A new form, P. 

 fragarioides, Linn., var. stolonifera, Maxim., forma trifoliolata , Takeda, 

 is also described: it is based on Henry, N°. 7895 from Hupeh, 

 China. T. A. Sprague. 



Takeda, H., The Japanese species of Cerastium. (Kew Bull. 

 Mise. Inf. N°. 2. p. 100-109, with plate. 1911.) 



11 species are enumerated as having been previously recorded 

 for Japan and Formosa: they are Cerastium pilosum, Ledeb., C. 

 oxalidiflorum, Makino, C. triviale, Link, C. pamiliim, Curtis, C. 

 Ianthes, F. N. Williams, C. glomeratum, Thuill., C. alpinum, Linn., 

 C. robustum, F. N. Williams, C. morrisonense, Hayata, C. arvense, 

 Linn., C. schisopetalum, Maxim. 



The author reduces C. oxalidiflorum to C. pilosum, and C. Ian- 

 thes to C. triviale. He considers that the records of C. pumilum, C. 

 glomeratum, C. arvense, and C. alpinum are based on erroneous 

 determinations and accordingly deletes these species. 



3 new species are described: C. rigidulum, Takeda, from the 

 Kurile Islands, C. boreale, Takeda, from Yezo and the Kurile 

 Islands, and C. Schmidtianum, Takeda, which is the plant incor- 

 rectly referred by A. Gray and Franchet et Savatier to C. Fi- 

 scherianum and C. alpinum var. Fischerianum respectively. C. cilia- 

 tum, Turcz. is recorded for the first time from Japan, where it was 

 collected in the alpine region of Mt. Shirouma, 3000 m. alt., by 

 Mr. Takeda. 



A Latin clavis to the species is appended, also a plate with 

 figures of the flowers and seeds of C. boreale, Schmidtianum, C. 

 rigidulum, C. robustum, and the flowers, capsule and seed of C. 

 ciliatum. T. A. Sprague. 



Takeda, H., The Saxifrages of Yezo and the Kurile Islands- 

 (Journ. Bot. IL p. 109—115. 1911.) 



The author enumerates the following species as oecurring in 

 Hokkaidö (i.e. Yezo and the Kurile Islands): Saxifraga sar- 

 mentosa, Linn. f., S. cortusifolia, Sieb, et Zucc, S. madida, Makino, 

 5. punctata, Linn., 5. fusca, Maxim., S. japonica, Boissieu, S. bron- 

 chialis, Linn., var. cherlerioides , Engl., 5. Merkii, Fischer, S. reflexa, 

 Hook., 5. rivularis, Linn., S. Fauriei, Boissieu. T. A. Sprague. 



Wernham, H. F., Anewgenusof Rubiaceae. (Journ. Bot. IL. 

 p. 317-318. 1911.) 



The author refers the genus, which is monotypic and called 

 Pteridocalyx {P. Appunii), to the Rondeletieae , pointing out that it 

 differs from the rest of the tribe by the basal insertion of the sta- 

 mens, the bifid stipules and the combination of contorted aestivation 

 with petaloid development of one or more of the calyx-lobes. Its 

 habitat is Demerara, where it was collected by Appun. The 

 nearest ally is Pallasia. J. Hutchinson.
