omalus Sudre. R. macrocalyx Hai. 1890 ist verwandt mit R. Gene- 

 vierii Bor. R. Crucimontanis n. sp. {Radulae) kann mit keiner Form 

 verglichen w^erden. R. orthosepalus Hai. ist mit R. brachystemon 

 verwandt, nicht aber mit R. piiocarpus Gremli. — Nicht zu verei- 

 nigen ist R. hennehergensis Sag. mit R. foliolatus Hai. — R. Richten 

 Hai. 1890 wird als verwandt mit R. Pveismanni bezeichnet. R. ele- 

 gantissimus n. sp. (verwandt mit R. Metschii Pocke). Die Hirtus- 

 artigen Brombeeren sind im Sem n aringgebiete nicht so formen- 

 reich wie anderwärts in den Voralpen. Neu fürs Kronland ist 

 R. crassus Hol. — R. nemot'osus Hayne machen im Gebiete den 

 Eindruck eines R. sulcatus^caesnts oder Grenili'^caesws.

Koidzumi, G., The Vegetation ofjaluit Island. (BotanicalMaga- 

 zine. Tokyo, XXIX, p. 242—257, 3 Fig. 1915.) 



The island lies in the moist tropical zone. The whole of the 

 main island is densely covered with Vegetation, which may be divi- 

 ded in three principal formations: I. The coral-rock formation. II. 

 The open sand-strand formation. III. The ßarringtonia formation 

 (Halophilous forest and bushland). There is a little cultivation in 

 the island. 



The author gives a list of the flowering plants and ferns naturally 

 found in the island. In this list one new name is mentioned: Peper- 

 omia pellucida Kunth var. obtusifoUa nov. var. (without description.) 



Of the 59 species mentioned in the list, 40 reached the island 

 by natural means, such as oceanic currents and birds (the island 

 is an atol), the remainder is inadvertently introduced by man. 



The flora of the island is extremely poor, Gramineae , Euphorbia- 

 ceae and Legwninosae being larger families represented in the 

 coUection. Of the remaining families of vascular plants there are 

 none that contain more than üve species, and the majority are 

 represented by but one or two. 



The Vegetation of the island is altogether derivative, and 

 apparently of comparatively recent origin; and the floral character 

 is distinctly that of an oceanic coral island. The scarcity of the 

 number of species in each family and also of the total number of 

 species lend support to this view. Jongmans. 



Makino, T., Two new genera M atsumurella Makino and 

 Ajugoides Makino. (Botanical Magazfne. Tokyo. XXIX. p. 279 — 



283. 1915.) 



The new genus Matsumurella is intermediate between Leonurus 

 Linn. and Ajugoides (Matsum. et Kudo) Makino. One species only 

 belongs to this genus M. tuberijera Mak. nom. nov., formerl}^ named 

 Leonurus iuberiferus Mak. 1905. 



The genus Ajugoides comes near to Stachys (it was formerly 

 described as a subgenus Ajugoides of this genus), Loxocalyx, Leonu- 

 rus and Lamiuni, and may be placed next to Matsumurella to which 

 it is very closely allied. It differs from Stachys by having truncate 

 nutlets, from Leonurus by its divergent anther-cells and non-spinous 

 calyx-teeth, from Loxocalyx by not having the distinctly obliquely 

 bilabiate calyx, and from Lamiian by having stolons and glabrous 

 anthers. To this genus belongs M. huniilis (Miq.) Makino nom. nov.
