(a) small inconspicuous glands situated on the upper surface of the 

 foliage leaves, where the three leaflets join the petiole ; and (b) large con- 

 spicuous glands borne on vestigial foliar structures — " bud scales" — 

 which are situated on the shoot below the foliage leaves. 



The morphological characters are discussed, and also the anatomical 

 structure of the nectaries. Extra-floral nectaries are usually regarded as 

 attracting ants to keep off insects injurious to the young foliage.

Nemalion, Cytological Studies on. By J. J. Wolfe (Ann. Bot. 

 xviii. October, 1904, pp. 609-627 ; 2 plates, 1 fig.).— A detailed cytological 

 study of Nemalion multifidum. The most important results are those con- 

 cerning the reproductive processes. The so-called spermatium is proved 

 to be an antheridium, which gives rise to two male cells. The conclusion is 

 reached that Nemalion presents the essentials of an antithetic alternation 

 of generations, and that the cystocarp is, therefore, the homologue of the 

 sporophyte in higher plants. Approximately 16 chromosomes are present 

 in the cells of the cystocarp up to spore formation, the reduction division 

 (to 8) being intimately associated with the production of carpospores.

Nerine Bowdeni. By W. Watson (Garcl. Chron. No. 935, p. 365, 

 fig. 164 ; Nov. 26, 1904). — A very ornamental Nerine has lately 

 been recognised as a new species which a few years ago was sent from 

 South Africa by a Mr. Cornish-Bowden to his mother, who grew and 

 flowered it for some years, and then sent some of the flowers to Kew, 

 where it was assumed that they were the blossoms of N. lucida ; but 

 later on, when the bulbs which had been distributed were flowered at Kew 

 and by others, it was found that the plant was a distinct species, nearly 

 allied to N. flexuosa, but with much larger flowers. The scape is 

 18 inches long and carries from six to twelve blossoms, which are larger 

 than those of any other species in cultivation. They are of a pale rose 

 colour, with a darker line down the middle of each segment, which is 

 3 inches in length and recurved at the tips. The stamens are as long as 

 the segments. — G. S. S. 



New European Plants. By Dr. F. Hock (Luckenwalde) (Beih. 

 Bot. Cent. xvii. pp. 195-210). — Records further immigrations and a whole 

 series of new localities for those previously recorded. Anthoxanthum 

 aristatwn is greatly increasing its range, as also Bromus briz&formis, 

 B. unioloides, Hordeum jubatum, Azolla caroliniana, &c. — G. F. S.-E. 



New Plants in Europe. By Dr. F. Hock (Beih. Bot. Gent. xv. 

 pp. 387-407). — Continues his list of foreign introductions. Twenty new 

 species are mentioned, including the Californian Lonicera Ledebou.rii, 

 Helianthus rigidus and Salpichroa rhomboidea. A number of new 

 habitats are also given for those previously reported. Amaranthus 

 cttudatus, A. albus, and A. paniculatus are recorded from twelve new 

 habitats ; Polygonum cuspidatum and P. oricntale from ten and twelve
