in Paris, large male and female macluras, which, in 1837, produced ripe fruit 

 with perfect seeds. (Annales d'Hort. de Paris, torn. xxi. p. 215.) 



Vhnas. — Elm leaves, as food for cattle. M. Poiteau, while on a horticul- 

 tural tour from Paris to Fontainebleau and Barres, between the latter place and 

 Nemours, found the boys and the girls of the neighbouring villages perched 

 on the elm trees which line the public road ; and not only gathering the 

 leaves, but breaking down the young shoots, in order to carry them home as 

 fodder for cows. Many trees had not a single leaf, except at the extremities 

 of the branches, which could not be reached by hand. M. Poiteau was in- 

 formed that this was the custom of the country; and that the elms on various 

 properties are kept pollarded, in order to facilitate the taking of the leaves and 

 young shoots by means of a short ladder. The leaves and shoots are found 

 highly nutritive to cattle, whether eaten in a green state, or after being dried, 

 and stacked for winter use. (Annates de la Societe d'Hort. de Paris, &c.) 



TaxjCcem. 



Salisburm adiantifolia fce'mina grows vigorously in the nursery of M. Gode- 

 froy, at Ville d'Avry ; but, having only been lately received, it has not been 

 much propagated. (Annates d'Hort. de Paris, 1837.) 



It grows readily from cuttings of the ripened young wood taken off with 

 a heel, planted in sand in a sandy border, and covered with a hand-glass. 

 There are plenty of young shoots pruned off annually from the female Salis- 

 bury in Kew Gardens, and we are therefore surprised that the tree is not 

 propagated in any of the nurseries, except at Messrs. Loddiges. — Cond.

Pinus, A^bies, Picea, fyc. — In the Annals of Natural History, vol. ii. p. 163., 

 is a paper entitled, " On the Genera Pinus and Abies, with Remarks on the 

 Cultivation of some Species. By Capt. S. E. Cook, R.N. Read at the 

 British Association, Newcastle-upon-Tyne, in August, 1838." The author 

 proposes to divide the seventy species described by botanists into five groups : 

 1. those of Old America; 2. those of the Rocky Mountains, which divide 

 the Atlantic from the Pacific, and which, as most of the species were made 

 known to us by Mr. Douglas, he proposes to call the " Douglas Group ;" 3. 

 those of the uplands of Mexico ; 4. those of the Himmalayan Mountains ; 

 and, 5., those of Europe. In speaking of the European group, Capt. Cook 

 considers P. uncinata and P. hispanica as distinct species ; and in which 

 opinion we think, judging from the plants raised from seeds received from 

 Capt. Cook, and now growing in the Horticultural Society's garden, he is 

 mistaken ; or, in other words, he considers as species what we consider only 

 as varieties. We decide on this point from the form of the buds, which, in 

 all the varieties of P. Laricio, including P. Laricio hispanica, have the buds 

 white, resinous, and terminated with a long point, like that of a camel-hair 

 pencil ; while in all the varieties of P. sylvestris, including P. s. uncinata, the 

 buds are short, blunt, brownish, and resinous. See Arb. Brit., p. 2153. and 

 p. 2200., with the different figures showing the buds of the different sorts. 



In the Arboretum, p. 2209., we have stated, on the authority of La Perouse, 

 that Capt. Cook's P. hispanica, which is La Perouse's P. pyrenaica, is found 

 in the Pyrenees, between the rivers Lassora and Cinca; but Capt. Cook 

 says that this forest is Spanish, and not French. We are much obliged to 

 Capt. Cook for the correction ; but it does not at all affect the question as to 

 P. hispanica being a variety of P. Laricio, which is what we deduce from 

 the evidence of living specimens acknowledged by Capt. Cook to be genuine, 

 altogether independently of geographical distribution. Our readers, by compar- 

 ing the tree named Pinus hispanica in the Horticultural Society's garden, with 

 P. Laricio, P. L. romana, and P. taurica, in the same garden ; and P. uncinata
