122 NOTES ON NEW OR RARE PLANTS. 



C^LOGYNE Wallichii— Dr. Wallich's Cselogyne. Found in great 

 abundance by Dr. Hooker on his approaching Darjeerling, in Sikkim, 

 Himalaya. It has bloomed beautifully in the collection at Chatsworth 

 during last summer and autumn. Sir W. J. Hooker states tliat on liis 

 last visit to Chatsworth, next to the flowering Victoria, this Ca;Iugyne 

 was the most interesting of the many botanical rarities collected in that 

 place. The pseudo-bulbs are very singular, flagon-shaped, dark green, 

 warted, and frequently covered with a strong coating of loose net-work, 

 formed by the old slieath. Only one flower arises at a time from each 

 bulb, and tliis springs forth when the leaf lias decayed. T!ie flower 

 stem rises about an inch and a half high. Eacli blossom is about four 

 inches across; sepals lance-shaped, pink; petals of similar form and 

 colour. The lip is very large, standing forward ; the colour is pink, 

 white, and yellow, dashed with red spots. It is a very interesting and 

 beautiful flowering species. It flourishes in the cooler division of the 

 orchid house, placed near the glass, and grown in turfy-peat, mixed 

 witli sphagnum moss. (Figured in Bot. Mag., 4496.) 



Ceanothus papillosus. — The Horticultural Society introduced 

 this pretty species from-California, and it proves to be quite liardy. 

 Tiained against a wall, it flourishes and blooms very freely. The 

 leaves are two inches long, narrow, and the flowers are borne in capi- 

 tate (headed) racemes, blue, with yellow anthers. (Figured in Bot. 

 Mag.) 



Ceanothus dentatus. — This pretty species was also introduced by 

 the Horticultural Society from California, and with a similar treatment 

 to the previous described species ; it thrives in the open air against a 

 wall. Both of tiiem do well in the greenhouse or conservatory, being: 

 very ornamental, and force well for winter and spring bloom. The 

 flowers are of a pale blue colour, borne in round heads, half-an-inch in 

 diameter, one cluster proceeding from the axil of each leaf. 



The Ceanothus answers admirably for training against a wall, but 

 grown in the shrub border, or in a pot, the plant grows long and 

 straggling, but if the leads be stopped, or pruned back to a proper 

 length, side shoots are freely produced, and the plant forms a pretty 

 bush. (Figured in Bot. Mag.) 



Chorozema flava. — Yellow-flowered. This handsome species 

 was, we believe, introduced into this country by Baron Hugel, who 

 sent it to the Eoyal Gardens of Kew. It is of medium grow th, bushy, 

 and blooms profusel}\ The flowers are borne in terminal, and axillary, 

 open, leafy racemes, of a deep yellow colour, with a few green veins 

 at the base, and the keel sulphur-coloured. Its delicate habit, shining 

 green leaves, and numerous pretty yellow blossoms, render it a very 

 desirable plant for the greenhouse. (Figured in Bot. Mag.) 



Clematis graveolens — Heavy-scented Traveller's Joy. It is a 

 native of Chinese Tartary and the snowy passes of western Himalaya, 

 at an elevation of 12,000 feet above the level of the sea. It Avas dis- 

 covered by Captain Munro, who sent seeds of it to England. It is in 

 the Koyal Gardens of Kew, and blooms throughout the sunuuer
