HEMSLEY, W. B., On the G e n u s Corynocarpus F o r s t. (Annais 

 of Botany. p. 743—761. Sept. 1903.) 



This species was established by the Forsters in 1776 from 

 specimens collected in NewZealand on Cooks second voyage. It 

 is described and figured by Sir J. Banks and Dr. Solander as 

 Merretia lucida. It was introduced to Kew in 1824, and figured by 

 Sir W. Hook er in the Botanical Magazine oi 1848 (C. laevigata), who 

 placed it doubtingly in Myrsinaceae. In 1852 Sir J. Hook er described 

 it in greater detail and placed it in Anacardiaceae, where it was also 

 placed in 1862 by Bentham and Hooker. Sir J. Hooker still held 

 the same view of its affinities in 1864. In 1897 Eng ler redescribed and 

 figured C. laevigata as the type of a new order: Corynocarpaceae, he 

 says the absence of resin-ducts excludes it from Anacardiaceae, and he 

 places it in his subseries Celastrineae. Our author considers the absence 

 of resin-ducts insufficient to separate it from Anacardiaceae, the members 

 of which it resembles in other characters. 



A description of the anatomy of the leaf and stem is given (the 

 work of Dr. F ritsch) but, except for the absence of resin-ducts, there 

 is nothing special to note. Descriptions of 2 new species are given: 

 C. similis Hemsl. and C. dissimilis Hemsl. This is followed by the 

 plant's economic history. W. C. Worsdell. 



HOOKER, J.D., Curtis's Bot. Mag. LXIX. No. 708. Dec. 1903. 



Descriptions and figures of the following plants are given: Meryta 

 Denhami, Agapetes Moorei, Echidnopsis somalensis, Restrepia antenni- 

 fera, Cotyledon undnlata. W. C. Worsdell.

With 205 plates from photographs and 35 illustrations from 



drawings. 



A populär little handbook referring to the wild and commonly culti- 

 vated shrubs of the northeastern United States. A systematic list 

 of the species considered, following the Bentham and Hooker 

 arrangement, is given, with a key to the principal groups. Detaüed 

 habit, bark, bud, leaf, flower and fruit characters are given under each 

 species, and a glossary of botanical terms and indexes of Latin and 

 English names make ready reference possible. Trelease. 



Knuth, R., Ueber die geographische Verbreitung und 

 die Anpassungserscheinungen der Gattung Gera- 

 nium im Verhältniss zu ihrer systematischen 

 Gliederung. (Engl. Jahrb. XXXII. 1903. p. 190—230.) 



Sämmtliche von den Autoren unterschiedenen Gruppen der Gattung 

 Geranium lassen sich auf drei Stämme zurückführen, deren Hauptgruppen 

 die Batrachia , die Batrachioidea und die Columbina sind. An die 

 Batrachia lassen sich die mediterranen Gruppen der Unguiculata, Sub- 

 acaulia und Tuberosa angliedern, ebenso die Polyqntha Central- 

 Asiens, sowie die Jucunoidea der mexicanischen Steppe; die Besiede- 

 lung Nordamerikas mit den Batrachia ist von Asien aus erfolgt. 



Das Haupt- Areal der Batrachioidea ist Westasien, Osteuropa, 

 Ost- und Südafrika; mit ihnen stehen die Incana der südafrikanischen 

 Hochsteppe in genetischem Zusammenhang. 



Der dritte Stamm, die Columbina, Robertiana, Anclina und Neuro- 

 phyllodes umfassend, ist über Westasien, Europa, Nord- und 

 Südamerika und den Sandwich-Archipel verbreitet; die nord- 

 afrikanischen Standorte sind erst später eingenommen worden.
