Messrs. J. Veitch & Sons from seeds collected at Szemao, in Yunnan, by 

 Mr. E. H. Wilson, when paying the writer a visit at that station in the 

 autumn of 1899. The tree is very ornamental, and produces most 

 valuable timber, but it is very doubtful if it will prove hardy in these 

 isles, except in the warm corners of South-western Ireland and Cornwall.

Lichens collected in Java, 1894-5. By Abbe Hue {Ann. Jard. 

 Bot. Buit. ser. ii. vol. ii. pt. ii. 1901, p. 171). — Identifications and 

 descriptions. — P. G. 



Lig-ularia macrophylla, Polygonum polystachyum, Senecio 

 pulcher, Stokesia cyanea. By G. Besoke {Die Gart. p. 493 ; 

 19/7/1902). — The first is well known as a foliage plant, while the other 

 three are strong, late autumn flowering plants, also well recommended 

 for pot culture. Stokesia cyanea was formerly often found on the 

 Continent as a market plant, the large, showy purple-blue flowers 

 appearing from October till December. Though quite hardy, it grows 

 often better under glass, especially as during our often sunless autumns 

 the flowers have little chance of expanding. — G. B. 



Lilac, To Bloom, in Autumn. By M. C. Renault {Ann. Soc. 

 Nant. p. 33 ; 1902). — M. Renault quotes an article in the Annals of the 

 Horticultural Society of Haute-Garonne describing how Lilac may be 

 made to flower in the autumn by stripping the bush of leaves in August 

 and then watering daily. It would probably quite prevent the tree 

 from flowering the following spring, but if successful might be worth 

 while for commercial purposes. — M. L. H. 



Lilies Of Japan. By P. Barr {Gard. Chron. No. 817, p. 129 ; Aug. 

 23, 1902). — The writer comments on the various Lilies which have been 

 imported from Japan and their varieties, and criticises the writings of 

 others on this subject. — G. S. S. 



Lisianthus (Gentianacese), Revision of the Species of. By 



J. Perkins {Engl. Bot. Jahrb. Vol. xxxi. 1902, pp. 489-494 ; 2/9/1902;.— 

 A systematic revision of the fifteen species of this West Indian and 

 Central American genus. — A. B. B. 



Lotus peliorhynchus. By Ed. Andre {Ann. Soc. He. p. 55 ; 

 February 1902). — This ornamental plant, from Teneriffe, where it grows 

 on the bare rocks in full sun, is cultivated in pots in Holland and 

 France, and in May suspended out of doors, where it remains till 

 September, when it is again removed to shelter till the following spring.

Lupines for Green-manuping\ By J. Burtt Davy {U.S.A. Exp. 

 Stn. California, Beport for 1897-8, pp. 203 to 225 ; plates and tabs.) — 

 This is a series of very interesting and valuable articles on this subject, 

 illustrated by several photographs. Green-manure crops are treated of 

 generally by way of introduction, and the advantages of plants of the 

 leguminous order (Clovers, Peas, Beans, Lupines, &c.) pointed out. The
