and brilliancy is compensated by the

delicate colour. All four species are 
much alike, their differences being such 
as none but a botanist can appreciate. 
Their general appearance, their foliage, 
their stipule*, their inflorescence . are all 
similar. They form a perfectly natural 
genus, approaching Amidd a 9 but dis-

remarks upon their cuitiva-

cultivated in a hot- 
house their period of flowering is hastened, as it may be also by other means. The soil they prefer is a light mixture of 
peat or leaf. mould and a little sand. They should be frequently watered. They may be 
under a bell-glass, in a moist atmosphere and on a warm bottom.'' 
The four species which M. Planchon enumerates are R. amcena, Menechma, Roei , and degans ; they seem to differ 
in very slight circumstances. In the same work this author proposes a genus, also cut off Rondei -a, for which he 
offers the name of Arachnothryx, and to which he refers the Rondeletias buddleioides, lanijfora, and rcjkxa of Bentham 
with the discolor of Humboldt and some others.

Roseworts. Native of the Himalayas. Flowers in September. Introduced to the Botanic Garden, 
Glasnevin, by Major Madden. (Fig. 96.) 
This very curious and handsome plant been a near relation to the Shrubby Potenti), so well known in Garden*. It 
was found in Sirmore by Capt. Gerard ; and we have a wild specimen from Dr. Royle, from some other part of the 
Himalayas. It forms a dwarf hairv bush, with weak spreading brown branches. The leaves are between pinnate and 
digitate, short-stalked, with membranous dilated brown stipules as long as the stal ; the leaflets vary in number from 
Ave to nine, are grey, oblong, rolled back at the edge, and much wrinkled, whitish and hairy on the underside ; th 
uppermost pair are decurrent at the base, the others taper to the point of insertion ; some are usually two-lohed. The 
flowers are terminal, nearly sessile in the garden specimen, but conspicuously stalked in those found by Capt. Gerard. 
There are five bracts external to the «lvx. linear-lanceolate, very hairy, with a distinct red scabrous keel ; the sepals are 
igular, yellow inside ; the petals near
