GLEANINGS AND ORIGINAL MEMORANDA. 



Cinchona Calisaya. The tree that yields the famous Calisaya bark, and which has 

 the reputation of being the most important kind for medicinal purposes. It has, we 

 understand, flowered for the first time in this country in the conservatory of J. E. 

 Howard, Esq., of Tottenham, where it has grown to some eight or ten feet in height. 

 Its unrivalled reputation for medicinal purposes gives much interest to it. Found in 

 Bolivia and Peru. 



A lofty tree, with an erect, ascending stem, often twice as thick as the human body, and. a leafy crown, over- 

 topping all the trees of its native forests ; bark thick, longitudinally and transversely fissured ; branches spreading.

 with pale veins, in the axils of which are rough depressions ; petiole short. Stipules oblong, obtuse, quite entire, 

 connected. Panicle large, diffuse, tomentose. Peduncles square and compressed ; main ones opposite, spreading ;

Ccelogyne barb ata. This fine Orchid has been flowered in both Sir Trevor Lawrence's 

 and Mr. Day's collections, who, we believe, furnished flowers to Professor Reichenbach 

 for the description given below. It is a handsome addition to the already fine genus 

 Coelogyne, and will most likely be found to thrive best under an intermediate temperature, 

 with plenty of water during the growing season, similar to C. cristata, and like that 

 well-known beautiful species, not to be kept so dry as the generality of Orchids, even 

 when at rest. We believe the plant was introduced by Mr. Bull, through his collector 

 Mr. Freeman. 



Panicle over two feet long, rigid, bearing eight stiff imbricate brown scales under the inflorescence. Labellum 

 trifid, with projecting triangular acute middle lacinia, three rows of narrow lamellae on the disk. Upper part 

 of column hooded, with toothed membrane round the anther. The stigmatic hollow is transverse under broad 

 projecting rostellum. Flowers white, with lamellae and ciliae brownish-black. — Gardener's Chronicle, N.S., 

 vol. xiii., p. 8.

 tiaceee). Blossoms in spring in the Royal Botanical Garden, Kew. (Fig. 72.)
