13. Blackwellia fagifolia. From China, in 1824. A plant with downy 

 branches, and ovate, serrated, bright-green alternate leaves, with linear, 

 subulate, pale-green deciduous stipulse. One of them flowered within a 

 few weeks after its arrival ; its blossoms grew in numerous axillary pen- 

 dulous simple racemes, about the length of the leaves, and were of a pale 

 yellowish white colour, emitting a fragrant odour. When in blossom this 

 plant is an object of much interest, not only on account of its pendulous 

 racemes of white flowers, which burst forth from the axillae of every leaf, 

 and fill the air with their perfume, but also for the sake of its beautiful 

 starry floral envelope, which, with its delicate fringe of shining white hairs, 

 exhibits one of the most elegantly symmetrical combinations in nature. 

 It is nearly a hardy plant, flowering in May. 



. 14. Eurya Chinensis. Abel. 15. Mimosa polydactyla. Willdenow. A 

 curious species of sensitive plant, which may be raised with facility from 

 seeds, which it produces in abundance ; but it has not been propagated in 

 any other manner. Like all sensitive plants, it requires, in order to acquire 

 its highest degree of irritability, to be cultivated under the influence of a 

 strong light, in a highly heated atmosphere, charged almost to saturation 

 with humidity. 



Herbaceous Plants. — 16. Calceolaria corym- 

 bosa. Ruiz and Pavon. Bot. Reg. 723. {Jig. 52.) 

 A beautiful plant, scarcely more than biennial, 

 usually'perishing after having perfected its seeds. 

 It requires, like most of the herbaceous plants 

 from Chile, a cool temperature, and humid at- 

 mosphere during both summer and winter. It 

 is managed most successfully by being placed in 

 a cold airy frame, which may be protected by 

 mats from severe frosts during the winter. In the 

 months of April, May, and June, it produces its 

 brilliant yellow corymbs of flowers in abund- 

 ance ; and these are, under favourable circum- 

 stances, succeeded by seeds, from which, if sown 

 immediately after ripening, fine young plants 

 may be obtained for flowering the following 

 summer. A native of shady places near Conception, where it is called by 

 the country people Arguenila.

Orchideous Plants. — 23. Catasetum Claveringi. Lind. This noble spe- 

 cies of Catasetum was brought from Bahia de S. Salvador in 1823. by Mr. 

 George Don. It grows on the stems of living trees, and consists chiefly of 

 a cluster of oblong bulbs, covered with the remains of the dry sheaths of the 

 leaves of former years. The leaves are lanceolate. The flowers are very 

 large, somewhat globular, quite free from pubescence, and having a power- 

 ful but pleasant smell of honey ; on the outside they are dingy green, in the 

 inside they are banded with irregular spots of a rich purple, like the flowers 

 of some kinds of stapelia. The labellum is very fleshy and solid, and over- 

 shadows the inside of the flower like an helmet ; in the inside it is bright 

 yellow, on the outside pale green. The column is very large, beautifully 

 spotted with purple, and has two long cirrhi in front, which being longer 

 than the columna, lie coiled up in the bottom of the labellum. A robust 

 stove plant, flowering in September. It has been named after Captain 

 Douglas Charles Clavering, F.R.S., &c. the commander of H.M.S. Pheasant 

 in the voyage during which the plant was collected.
