About one-third of the cuttings prepared in this way perish ; but the re- 

 mainder, by their vigorous growth and the certainty of their never sending up 

 suckers, fully compensate for the loss. The reason of so many of the cuttings 

 perishing is, that cuttings made by the ordinary process send out roots from 

 the remains of every eye under ground as soon as the growing season com- 

 mences ; whereas by the method now recommended every vestige of the bud is 

 removed, and the roots issue from every part of the stem, but are sent forth at 

 a much later period of the season, and consequently the buds drop off before the 

 cuttings are furnished with roots for their support. The usual depth to plant 

 the cuttings is from four to six inches.

DICOTYLEDONES. 



BOMBACE^E. Kunth. 



Plagianthus Lampenii. Booth. MSS. Mr. Lampen's Plagianthus. Bot. 

 Beg. N. S. p. 22. Raised about five years ago by the Rev. R. Lampen, from 

 seeds sent from Van Diemen's Land, where it is said to be a native. It is very 

 hardy, and is likely to prove an interesting addition to our hardy evergreens. 

 It is known about London under the erroneous name of Sida Pidchella. Bot. Reg. 



BUTACEiE. Juss. 



Boronia crenulata. Smith. Crenulated Boronia. Bot. Beg. N. S. t. 12. 

 A native of King George's Sound, where it was found by Mr. Menzies, during 

 the voyage of Vancouver, and described by Sir James Edward Smith from 

 specimens then brought over. It is, however, a new introduction to our gardens, 

 and one of the handsomest of the whole genus. The drawing was taken from a 

 specimen in Messrs. Loddiges 1 collection. It may be increased by cuttings or 

 layers. Bot. Beg. 



LEGUMINOSJE. Juss. 



Acacia semi-verticillata ; glabra, phyllodiis semi-verticillatis subulato-linea- 

 ribus pungentibus, uninerviis, spicis axillaribus solitariis : petalis 4-fidis recurvis. 



This species is allied to A. verticittata, Willd. ; but from that species it is 

 certainly distinct, both in habit and in general appearance. The leaves are in 

 threes, arranged in half-whorls, erect, and are more fleshy and thick than those 

 of verticittata, as indeed is the whole plant. They are also alternately disposed, 

 and the young branches are perfectly smooth. The flowers are disposed in 

 spikes, of from six to ten in a cluster in the centre of the branch, and not as in 

 A. verticittata, which are from the base to the apex ; the flowers are also less 

 crowded. It is a native of New Holland, and was raised from seeds which were 

 presented to the Birmingham Botanic Garden by the Right Honourable the 

 Earl Mountnorris. Seeds were also presented about the same time by J. W. 

 Crompton, Esq. and J oseph Hodgson, Esq.
