contrast lo the "wet forest" which is more mixed as regards trees, 

 and has a very dense undergrowth ; Cyathea kermadecensis forms an 

 important endemic sub-tormation of dense forest with a luxuriant 

 growth of ferns and mosses on standing and fallen stems. The 

 series of excellent photographs in the plates give typical v^iews of 

 these plant formations. A chapter on geographical distribution gives 

 an analysis of the flora and its relation to that of neighbouring 

 islands and floral provinces. A füll list of 114 species, of which 

 12 are endemic, concludes this memoir. W. G. Smith.

Mitten im Cresund liegt die kleine schwedische Insel Hoen. 

 Fast das ganze Areal besteht aus kultivierten Boden oder "Weiden. 

 Nur ein sehr unbedeutender angepflanzter Laubwald kommt vor. 

 Nach einer topographischen und geologischen Uebersicht wird ein 

 Verzeichnis aller auf der Insel angetroffener Gefässpflanzen gelie- 

 fert. Von diesen weisen wir nur auf Equiseturn niaximuni, das in 

 Schweden nicht anderswo vorkommt, hin.

The author sets forth his views on four species of Opuntia now

 sons for disagreeing with a recent paper on the Cacti of India. A 

 Short instructive final paragraph is devoted to notes on the method 

 of distribution. W. G. Craib (Kew).

 Arizona. (U. S. Forest Service, Circ. CXCVII. p. 3—19. pl. 1—2. 

 fig. 1. 1912.) 



Utah juniper, Junipevus utahensis, the most important tree in 

 the forests of central Arizona is distributed from the western 

 Foothills of the Wasatch mountains in eastern Utah to southeastern 

 California and throughout northern and central Arizona, western 

 Colorado and southern W3'oming, especially on the high plateaux 

 4800-7000 feet; bordering the desert. The authors consider its 

 botanical characteristics, site requirements and associated species, 

 siem and crown, root sj^stem, reproduction, injuries by fungi, 

 mistletoe, fire and cattle, growth, while volume tables add to the 

 value of the bulletin. The yield, utilization and management are 

 given. Harshberger.

The author states that after manj' years stud}' he is satisfied 

 that Rubiis glareostis is a distinct species. It has been found in 

 several of the southern counties of England. An English descrip- 

 tion is appended also a short-tabular key. M. L. Green (Kew).
