124 A SCHOOL FLORA. 



In Labiata, seventeen species of Stenogyne, a genus peculiar to the 

 islands, are enumerated, five of them new. Gray's section Nato- 

 trichium of Ptilotiis is raised to generic rank ; it is based on Ptilotus 

 sandwicensis, and two more species are added* Euphorbiacece are not 

 numerous, seventeen species being described, one only being new 

 and five introduced. 



The Monocotyledons are not very numerous, and the novelties 

 are comparatively few ; there are only three Orchids, one, Habenaria 

 holochila, being new. Most of the new species are among the 

 Gyperacece and Grasses ; among the latter, the genus Ercujrostis is 

 notable as having five novelties and three introductions out of a 

 total of eleven species. Amoi 



nine species, holds the first place, but the proportion of new species 

 is greater in Lindsaya, four out of eight being first described. 

 There is a new genus, Schizostege, founded on the plant described by 

 Baker as Cheilanthes Lidgatii. 



A word of praise is due to the Darmstadt printer for the 

 admirable manner in which he has executed his task. 



A School Flora for the use of Elementary Botanical Classes. By W. 



Marshall Watts, D.Sc. (Lond.), Physical Science Master in 

 the Giggleswick Grammar School. Bevised and enlarged 

 edition. Bivingtons, 1887. 8vo, pp. viii. 199. 



This is an extremely useful little volume, intended u to provide 

 the student who has mastered the elements of botanical science 

 with a Flora of such small size as to be easily carried on country 

 rambles, which shall enable him easily to identify the common 

 plants with which he will meet." It is arranged throughout on the 

 principle of determining a plant by deciding which of two opposite 

 characters it possesses, and the plan is well executed. The typo- 

 graphy and arrangement are excellent, and the book might well be 

 adopted as a text-book in school natural history societies. 



The first edition, which we have not seen, was compiled for the 

 young botanists of Giggleswick School, and confined to the plants 

 of that district ; but it is now enlarged so as to include the species 

 marked with a higher number than 50 in the 8th edition of the 

 4 London Catalogue,' and the rarer plants growing within reach of 

 certain schools have been included. These have been ascertained 

 by lists furnished by those connected with the schools enumerated. 

 Among those absent from the list we note Eton, Harrow, and 

 Stonyhurst : Eton has never done much in the way of botany, but 

 the Flora of Harrow and the Stonyhurst list are easily accessible. 

 Of course in a book of this kind critical distinctions would be 

 out of place ; it is pleasant to meet once more our old friends 



ttammcidus aquatilis, Fatbits fruticosus, and Rosa canina. One or two 

 omissions surprise us : there is only one Drosera, for example, ana 

 one Erythraa. The authors' names are not attached to the genera 

 or species, which we think an undesirable omission, as it is desirable 

 to accustom young botanists to the correct method of citing names. 

 A useful little glossary is appended.
