NHW AND RARE FLANTS. 41 



Succeed, should lie planted on rock-work. It blooms in July and August. Each 

 flower is about an inch and a half across, of colour, with a whitish eye. 



It is a very pretty flowering plant, and a valuable addition to rock plants. 



Grabowskia duplicata. — Toothed. (Bot. Mag. 3841.) Solaneae. Pen- 

 tandria Monogynia. Mr. Tweedie sent seeds from Buenos Ayres to Mr. Moore 

 of the Glasnevin Botanic Garden, with whom it has bloomed. It requires a 

 moderate stove-heat. It is a rambling shrubby plant, growing to twelve feet 

 high. The flowers are produced in fascicles, from among trie upper leaves. 

 Each flower is about half an inch long, of a greenish white. 



Hibiscus Wray/e- — Mrs. Wray's Hibiscus. (Bot. Reg. 69.) Malvaceae. 

 Monadelphia Polyandria. Dr. Lindley states that his first knowledge of this 

 plant in a living state was from Mrs. Wray of Oakfield, near Cheltenham, send- 

 ing- him specimens. That lady has been singularly successful in raising rare and 

 beautiful plants. Mr. Drummond had collected seeds at the Swan River colonv, 

 and from a plant so obtained, it has bloomed in the garden of the London Hor- 

 ticultural Society. It is a shrubby greenhouse plant, growing to eight or ten 

 feet high in one season, if allowed plenty of root room. The plant at the So- 

 ciety's garden has been in bloom since the end of September, and is likely to 

 continue blooming, Dr. Lindley observes, throughout winter and spring. This 

 renders the plant a very valuable acquisition for a greenhouse or conservatory. 

 Each flower is about four inches across, of a pretty lilac colour. The plant is 

 readily propagated either by layers or cuttings. 



Isomerts arborea. — Tree-like Isomeris. (Bot. Mag. 3842.) Capparideae. 

 Hexandria Monogynia. This shrubby plant was discovered by Mr. Nuttall in 

 California, and sent to the Royal Botanic Garden, Edinburgh. At first sight 

 it strongly resembles a small-flowered Edwardsia. In a stove belonging to the 

 Caledonian Horticultural Society it has bloomed ; the top of the plant had been 

 secured in a pendant position, and Mr. McNab thinks this promoted its bloom- 

 ing. The flowers are produced numerously, solitary in the axils of the leaves, 

 but they are collected into terminal pseudo-racemes. Each blossom is near an 

 inch long, of a bright yellow colour. 



Monoi.opia major. — Larger Monolopia. (Bot. Mag. 3839.) Composita?. 

 Syngenesia Superflua. A native of California, from whence it was sent by 

 Mr. Douglas. It has been distributed in this country under the name Hele- 

 nium Douglassii. It is an annual, which grows from two to three feet hi«-h, 

 every shoot terminating with a flower. Each blossom is near two inches across, 

 of a bright yellow colour. The appearance of the flower is somewhat like that 

 of a Gaillardia, without a dark eye. 



Oncidium leucochilum. — White lipped. (Pax. Mag. Bot. 241.) Orchidacea?. 

 Gynandria Monandria. Sent from Guatemala to Mr. G. H. Bunney, of the 

 Kingsland nursery. It has bloomed in the collection of the Hon. Baron Dims- 

 dale, Campfield-place, Herts, under the skilful management of Mr. Dunsford. 

 It had a scape nine feet long, with thirteen or fourteen lateral branches, which 

 were from half a yard to four feet long, the whole beautifully bedecked with its 

 finely variegated blossoms. Each flower is near two inches across. Sepals and 

 petals of a greenish-yellow, marked and blotched with brown velvet. Labellum 

 white, stained with rose. It is a very interesting and beautiful species, deserving 

 a place in every collection. Mr. Dunsford did not plant it in heath soil, as is 

 usually done to the Oncidiums, but had a pot nearly filled with drainage, upon 

 which he reduced a sufficiency of moss, in which he fixed the plant. In this it 

 required a free supply of water, and the result was it grew most vigorously, and 

 is an evidence of the great advantage of cultivating many other Orchideae in 

 the same manner. 



Puya heterophyi.i.a. — Various leaved. (Bot. Reg. 71.) Bromeliaceae. 

 Hexandria Monogynia. It has bloomed in the collection of John Rogers, Esq., 

 jim., Sevenuaks, Kent, who received it from Mexico in 1838. The flowers are 

 produced in a close oblong spike, of a pretty flesh-colour, shaded with rosy- 

 carmine. 



Rjoidelu fi.ammea. — Flame-coloured. (Pax. Mag. Bot. 247.) Iridaceae.
