winter as possible ; (3) spray with Bordeaux mixture (copper sulphate 

 8 lb., quicklime 10 lb., water 50 galls.) as soon as the tips of the 

 green leaves are visible beyond the bud scales, and again about ten days 

 later with a weaker solution (copper sulphate 5 lb., quicklime 7 lb., 

 water 50 galls.). (See also Journ. E.H.S. xxviii. 293.) — F. J. C. 



Peliosanthes Teta Andr., var. Mantegazziana Pampanini. By 

 K. Pampanini (Bull. B. Soc. Tosc. Ort. 2, p. 50, Feb. 1905).— This 

 graceful plant was obtained from seed from Penang in 1901 through 

 Professor P. Mantegazza ; it is distinguished from the type chiefly by the 

 foliage, which constitutes its special character. While the type has rigid, 

 broadly ovate-lanceolate leaves, with a petiole shorter than the blade, the 

 variety is more delicate in habit, the leaves more flexile, with the petiole 

 longer than the blade, which is narrowly linear-lanceolate and very 

 acuminate. There are 3-5 parallel, projecting veins, of a deep green 

 colour, which add to the gracefulness of the leaf. Its long, elegant spike 

 of tiny flowers is of a pale green colour, absolutely scentless, and of short 

 duration. Its culture is not difficult. Hitherto the writer has cultivated 

 it solely in a hot-house, but is convinced it can also be grown in a cold 

 one, as its native habitat is in the moist, not very warm, mountain forests 

 of Malabar, the Himalayas, the Malay Peninsula and adjoining islands. As 

 they are plants possessing rhizomes, and of robust vitality, they should 

 come into favour with horticulturists. — W. C. W. 



Peppermint. By Alice Henkel (U.S.A. Dep. Ayr. Bur. PL Ind. 

 Bull. 90, Part III. ; figs.). — A detailed description of peppermint grow- 

 ing and distilling in the United States, where planters and agents have 

 made a determined effort to capture the British market for peppermint oil. 



The countries where the peppermint is cultivated most extensively 

 are still England, the United States, and Japan. In this last country it 

 has been grown before the Christian era, but the plant cultivated is not 

 Mentha piperitis vulgaris or officinalis, as with us and in America, but 

 Mentha arvensis piperascens, which is different not only botanically, 

 but in taste and smell. 



Peppermint oil to the value of $31,798 was exported to this country 

 by the United States in the fiscal year ending June 30, 1901, and a good 

 deal was also sent to various British colonies. — M. L. H.
