St. Ignatius beans of commerce appcar to be the product of 

 two species, one being Strychnos Ignatii, Berg., as described and 

 figured in Hook. Icon. t. 2212 the other an imperfectly known plant, 

 perhaps the new species described as S. lanata, A. W. Hill. 



The various species from the Philippines and E. Indies 

 have been revised and the following new species described: 5. pseudo- 

 tieutd, A. W. Hill from Malaya formerly confused with the Javan 

 5. Heute, Lasch.; S. Vitiensis, A. W. Hill, from the Fiji Islands 

 formerly confused with 5. colubrina; S. villosa, A. W. Hill from 

 Java; 5. merrillii, A. W. Hill from Luzon; S. dubia, A. W. Hill 

 and 5. lanaka, A. W. Hill from Mindanao. Plates of 5. Ignatii 

 and 5. multiflora and text figures of the flowers of 5. Horsfieldiana, 

 S. polytrichantha, S. dubia,, S. lanata and fruit of S. multiflora are 

 included. A. W. Hill (Kew). 



Jensen, C, Floristik fra Allindelille Fredskov [Floristi- 

 cal Notes from the forest Allindelille Fredskov, Den- 

 mark]. (Biol. Arb. tilegnede Eug. Warming. Köbenhavn, 1911. 

 p. 57-72. 3 figs.) 



The forest Allindelille Fredskov is situated in the middle 

 of the Danish island Sja'lland; the Underground is chalk, more 

 or less covered with morainic deposits. The main tree of the woody 

 part is beech (Fagus), and the Vegetation is often more open than 

 is usually the case with Danish beech- woods; the under-growth is 

 mostly Coruus sanguinea, Prunus spinosa, Crataegus oxyacantha, 

 Viburnum opulus. 



The author sub-divides the forest into three categories, viz. : 1. 

 rieh mild humous soil with good beech-wood, poor humous soil 

 where the chalk comes to the surface, mostly with shrubs, 3. peaty 

 soil (moor and fen). He gives a list for each category of the species 

 found there and descriptive notes on the Vegetation. The forest is 

 famous in Denmark for its many Orchidaceae {Epipogon, Aceras, 

 3 Cephalanthera' s, Ophrys museifera, etc.), and the number of spe- 

 cies of plants is much larger than in the woods of the surrounding 

 country. 



Some considerations are given about the oecurrence of humous- 

 loving species upon the humous-wanting, chalk}'- soil.

The area is on the Firth of Clyde in Argyleshire. The 

 relation between topography and Vegetation has been observed over 

 a considerable area extending from sea-level up to summits reaching 

 800 metres altitude; the physical features are illustrated in a useful
