BOTANICAL NOTICES OF NEW PLANTS.

Dr. Macfadyen says, that the stinging sensation may be removed by rubbing, so 

 as to bruise the hairs, and by afterwards smearing with oil the part affected : or 

 it is said the bristles will attach themselves to the rim of a hat passed over the 

 skin, and may thus be withdrawn. Bot. Reg. 



RHAMNACEiE. D. C. 



Trymalium odoratissimum. Lindl. Sweet-smelling Trymalium. Bot. Reg. 

 N. S. This genus has lately been established by Mr. Fenzl for the supposed 

 species of Ceanothus inhabiting New Holland. They differ from the genus 

 Pomaderris, of which many have the habit, in the presence of a distinct plaited 

 disc surrounding the ovary, and from Ceanothus in their indehiscent fruit. 



The species now defined is a new and very interesting addition to the genus ; 

 it was introduced from Swan River by R. Mangles, Esq., by whom a plant in 

 flower was presented to the Horticultural Society of London in 1838. Mr. 

 Mackay, the gardener at Sunning Hill, states, that the wood is soft or pithy, 

 and that the plant is apt to damp off in winter, if over-potted and not kept in 

 a warm and light situation. Bot. Reg. 



PASSIFLORACE^. Lindl. PASSIFLOREjE. Juss. 



Passiflora onychina. Lindl. Lieut. Sulivan's Passion Flower. Bot. Reg. 

 N. S. t. 21. This is a very pretty species, but by no means equal to many at 

 present in cultivation for beauty. 



It was introduced by Bartholomew James Sulivan, Esq., of her Majesty's ship 

 the Beagle, who procured seeds of it from the Botanical Garden, Rio de J aneiro, 

 in the year 1837, and presented them to Sir Charles Lemon, Bart., in whose 

 garden the present plant originated. It has also been introduced by Mr. Lowe, 

 of the Clapton nursery. The drawing was obtained from the stove of Miss Trail, 

 Bromley, Kent, in the beginning of last November, who at the same time sent 

 the following note : — " It is planted in a border, and from having been so placed 

 for above twelve months without showing bloom, the gardener pruned it 

 severely last spring, when it shot out with redoubled vigour. It is not known 

 whether it will bear a cooler atmosphere. It does not show seed. Its time of 

 flowering appears to be during the latter end of October, and through November. 

 The soil it at present grows in is a rich sandy loam. The specific name Onychina 

 was given to it in allusion to the blue colour of the flowers.'" Bot. Reg. 



CACTEiE. Joss. 



Mammillaria floribunda. Hook. Copious-flowered Mammillaria. Bot. 

 Mag. t. 3647. This is really a beautiful species of Mammillaria, imported by 

 Mr. Hutchins, from Chili, and now in the possession of Mr. Mackie, of the 

 Norwich Nursery. It is allied to M. atrata, t. 3642, differing, however, in its 

 stouter habit, larger, and more closely placed, and more projecting mammillae, 

 the stouter, and coarser aculei, larger flowers, and very unequal petals, which 

 are moreover of a paler red colour, yellowish in their lower part. Bot. Mag.
