NEW OR RARE PLANTS. 



(Noticed since our last.) 



AGAVE SAPONARIA. The Soap Aloe. (Bot. Reg. 55. 



HEXANDRIA MONOGYMA. 



This species, unlike the gigantic kinds A. americana, &c, flowers very 

 freely and does not then perish. The blossoms are produced on a long spike, 

 and before opening, have the appearance of a tuberose spike, they are green 

 outside and yellow within ; each flower is about an inch across. 



In Peru the plant is used as a substitute for soap. It requires but a sim- 

 ple treatment to induce it to bloom freely. It must be kept in the greenhouse, 

 dry in winter, and watered on the return of spring ; equal portions of loam 

 and sand form a suitable soil in which it grows satisfactory. Agave, from 

 Agavon, Admirable, alluding to its many useful purposes. 



AMYGDALUSINCANA. Hoary leaved. (Bot. Reg. 58. 



1COSANDRIA MONOGYMA. 



This species has been confounded with A. man a, but it is very different 

 its leaves being thickly covered with hoariness beneath, whilst the A. nana 

 is smooth on both sides; the leaves of the latter are finely serrated, and the 

 other coarsely. The flowers are of a pale rose, each blossom being about 

 half an inch across ; the shrub is quite hardy, middle sized, and has bloomed 

 in the shrubbery of Sir Oswald Mosley, Bart., Rolleston hall, Derby. 



ANGELONIA GARDNERII. Mr. Gardner's. (Bot. Mag. 3754. 



DIDYNAMIA ANGIOSPERMIA. 



Mr. Gardener sent seeds of this pretty flowering species from Brazil to 

 to the Glasgow Botanic Garden in 1838, and plants have bloomed this sum- 

 mer in the plant stove ; the plant appears lo be half shrubby, growing erect 

 to about three feet high ; the flowers are produced at the ends of the 

 branches, in long fracteated racemes, they are of a fine purple, each having 

 a white centre beautifully spotted with red, and being about an inch across. 

 It is very probable it will be found to flourish well in the greenhouse, if so, 

 it will be highly ornamental through the summer, Angelonia, from Angelon, 

 the native name of one species. 



ARISTOLOCHIA CILIATA. Fringe flowered. (Bot. Mag. 3756. 



GYNANDRIA HEXANDRIA. 



Seeds of it were sent by Mr. Tweedie, from Buenos Ayres, to the Glasgow 

 Botanic Garden, where a plant has bloomed; it appears to flourish in the 

 greenhouse; the stem is weakly, yet not climbing. The flower is of a green- 

 ish yellow outside, and internally of a deep purple brown, with yellow reti- 

 culations, which produce a very pretty effect ; the edge of the flower has a 

 fine fringe near half an inch long which has an interesting appearance.
