Alpine Plants, Rare. By S. Amott {Gard. Mag. 2,484, p. 857 ; 

 8/6/1901). — Bamondia serhica var. NathalicB, Androsace sarmentosa var. 

 Chitmbyi, Veronica Balfouriana, and others are described, and useful notes

Amaryllis (Hippeastrum) procera. By Angiolo Pucci {Jhdl. 

 B. Soc. Tosc. Ori. 7, p. 199; July 1901). — This species is known to be 

 difficult of flowering. It is a native of Brazil. During the summer it 

 should be kept in the open air in a ventilated but very insolated position ; 

 in the beginning of autumn it should be transferred to a temperate green- 

 house and exposed to full light. Following this treatment the plant will 

 flower easily the next spring. The bulb is much elongated, appearing 

 like a tunicated shoot, which is persistent, swollen at the base, 60 cm. to 

 a metre high, resembling somewhat the shoot of a Crinum, bearing 

 several broad, long, recurved leaves at the summit. The flowering shoot 

 is short, proceeding from the centre and bearing many flowers. The 

 latter are disposed horizontally ; the five petals form a tube 1 5 cm. long, 

 somewhat widened at the end, where the petals are prolonged into 

 acuminate teeth. The flower is of a violet-pink colour, with reticulate 

 nervation. — W. C. W. 



America, Central. By Mr. J. Donnell Smith (Bot. Gaz. vol. xxxi. 

 p. 108 ; No. 2). — Describes nearly thirty new species of nearly as many 

 genera. — G. H. 



American Florists, Society of. — Report of Proceedings of the 

 sixteenth Annual Convention at New York City, August 1900 (175 pages), 

 including president's address ; report of the ladies' drive on the afternoon 

 of the first day and evening lecture on floral decoration. Second day's 

 proceedings, including paper and discussion on greenhouse construction 

 and evening lecture on American floriculture. Third day's proceedings 

 devoted especially to the Carnation. Fourth and last day to sports. Gives 

 a very good idea of how American horticultural societies are run. — D. H. 



Analysis of Ash of Cabbage Plants. By Zawodny (in Berlin) 

 {Beih. Boi. Cent. bd. 11, ht. 1, p. 46). — Three tables are given in this 

 paper showing the differences in percentages of various minerals in 

 plumules, radicles, testa, and leaves and roots. The following may serve 

 as an example : —

 small plants and with kohl rabi conns and roots.— G. F. S.-E.
