LIST OF NEW AND RARE PLANTS. 



NOTICED IN PERIODICALS. 



Anchusa petiolata. — Petiolated-leaved Alkanet. (Bot. Mag. 3858.) Bo- 

 raginese. Pentandria Monogynia. Seeds of it were sent irura Nepal by Co- 

 lonel Colvin to the Glasgow Botanic Garden, where it flowered in the greenhouse 

 last October, but there is no doubt it will flourish in the open border in summer 

 and autumn, where it will prove a very interesting ornament. It is an herbaceous 

 perennial, growing erect, and producing numerous lateral racemes of flowers, 

 giving it a paniculated appearance. The flowers are of a pietty deep purple- 

 blue. Each blossom about half an inch across. 



Batatas bonariensis. — Buenos Ayres Batatas. (Pax. Mag. Bot. 25.) Con- 

 volvulacese. Pentandria Monogynia. It was sent to this country from Buenos 

 Ayres in 1839, by Mr. Two* die. It is known by some as Ipomea Bonariensis, 

 hut the genus Batatas is founded on the circumstance of the ovary having four 

 cells, whilst in Ipomea it has but two. It will flourish well in a warm greenhouse 

 or conservatory, though it is considered a stove plant. It is an herbaceous, 

 climbing perennial, the twining stems extending to twenty or thirty feet, but 

 readily coils around a low frame-work, and blooms very freely. The flower is of 

 a rosy-pink, with deeper coloured striped plaits. Each flower is about four 

 inches across. It deserves a place wherever it can he cultivated. 



Brassia Lawrenceana. — Mrs. Lawrence's Brassia. (Bot. Reg. 18.) Or- 

 chidace*. Gynandria Monandria. A native of Brazil, and has bloomed in 

 the very choice collection of Mrs. Lawrence, at Ealing park. Sepals and petals 

 of a golden yellow, blotched with light red. Labellum of a paler yellow, with 

 a white centre. Each flower is about five inches across, but the sepals and petals 

 are nut above a quarter of an inch broad. The flowers are very sweet scented. 



Callistachys i.ongifolia. — Long-leaved. (Pax. Mag. Bot. 31.) Legu- 

 minosae. Deeandria Monogynia. A native of the Swan River colony, and has 

 been raised by Mr. Low, in the Clapton nursery. The leaves are seven inches 

 long, very like those of a willow. The plant grows rather straggling, four or 

 five feet high, and thrives best in an airy greenhouse. The flowers are produced 

 in terminal spikes, not only at the extremity of the main shoot, but at the lateral 

 ones, each spike having about twenty flowers. The vexillum is of a pale yel- 

 low. Wings reddish-purple. Keel pinkish-white, tinged with purple. Each 

 blossom is about an inch across. By stopping the principal stem of the plant at 

 an early stage of its growth, and cause it to. produce numerous lateral shoots, 

 even by stopping the laterals too, if found requisite, the plant would probably 

 bloom profusely in a dwarfish condition, and thus be more suited for any green- 

 house. — Calistachys, from Kallos beauty ; and Stachys, a spike ; referring to 

 spikes of flowers. 



Cynoches Loddigesii; vak. Leucochilum.— Mr. Loddige's Swan Wortj 

 white-lipped var. (Bot. Mag. 3855.) Orchidacesc. Gynandria Monogynia. A 

 native of Guiana, and has bloomed in the collection of Mr. Moss, of Otterspool, 

 near Liverpool. The blossoms are very fragrant. Sepals and petals of a yel- 

 lowish-greeu, with transverse blotches of reddish-brown. Lip white, tipped with 

 yellow-green, the claw spotted with red. Each flower is about five inches across. 

 The scape contains many flowers. 



IIf.i.ichkyslm niveum. — Snowy flowered. (Bot. Mag. 3857.) Compositas. 

 Byngenesia JiqualiB. A native of Swan River, raised in the Clapton nursery. 

 The stem rises to a yard high, and the flowers are produced numerously in a 

 terminal capitula of subsimple corymbose branches, white with yellow disk. 

 Each flower is about two inches across. It deserves a place in every flown 

 border, where it blooms from July to the end of summer. It is a perrennial. 



li-oM.KA ficifoi.ia — Fig-leaved. (Bot. Reg. 13.) Convolvulacerr. Pentan- 

 dria Monogynia. It is probably a native of Buenos Ayres. It has been raised
