TENDER PLANTS FOR A WARM CORNER. 



197 



Holhoellia latifolia, Himalaya. — An evergreen climber of the 

 family Berberidaceae, with ternate or quinate leaves, allied to Akehia. 

 Stands well against Cactus House. Sometimes known as Stauntonia. 



Ipomoea Purga; Mexico. — The plant yielding the drug Jalap. 

 Growing against Palm House this is sometimes very ornamental, with 

 its numerous large purple flowers. During the past hot summer it 

 grew freely but did not flower. A perfect perennial in the above 

 position. 



Jasminum primulinum, Western China. — Has grown on an east 

 wall for some years, and might be good with careful treatment. 



Mutisia decurrens {Bot. Mag. t. 5273), Chihan Andes. — This is a 

 well-known choice climber, producing fine orange flowers 6 inches 

 across. It has done fairly well against the east side of Palm House. 

 It is best increased from seed, which I believe may be obtained most 

 successfully by crossing different plants. — M. ilicifolia, Chile. — Differs 

 considerably from M. decurrens, but is well worth growing. The 

 flowers are white or rosy-red. It used to grow at Eeigate 'in Mr. 

 Wilson Saunders' garden on a stick in the open. Treated like 

 M. decurrens it should be quite safe. 



Ruhus australis, New Zealand. — One of the most curious of the 

 genus. The leaflets are either absent or are reduced to mere points, 

 while the petioles and petiolules are apparently increased in length. 

 The entire plant is covered with small prickles. Does well against 

 Palm House. 



Smilax aspera, * Prickly Ivy, ' South Europe. — An attractive 

 small and very densely growing species, very dark in colour, and often 

 spotted. This and *S'. rotundifolia both grow against the Temperate 

 House. The genus Smilax is interesting as alone possessing tendrils 

 which ,are formed from stipules. 



Herbaceous plants growing in warm corners at Cambridge include : 

 Amicia Zygomeris, Mexico. — An interesting, rare, and pretty plant, 

 in summer reaching a height of 6 feet, and quite at home in an angle 

 formed by stove and corridor. It is leguminous, with pinnate leaves, 

 the leaflets exceptional in their obcordate or cuneate-emarginate form. 

 Is most remarkable in the large stipules which protect the unfolded 

 leaves. 



Calceolaria Sinclairi (Bot. Mag. t. 6597), New Zealand. — Is per- 

 fectly safe, apparently, planted in narrow border against Cool Fern 

 House. It belongs to the same section of the genus as C. violacea, a 

 native of South America, the home of the genus. It has a two-lipped 

 corolla of pale-lilac within, spotted with red-purple. A pretty and 

 choice plant. Several other kinds only require a similar position. 



Iris hexagona (Bot. Mag. t. 6787), Southern United States. — A 

 fine but somewhat tender Iris, doing well in the angle formed by Palm 

 House and the Aquarium. /. unguicularis [I. stylosa), {Bot. Mag. 

 t. 5773), native of North Africa, though hardier profits by the same 

 position. 



Jahorosa integrifolia, Argentine. — Is an interesting plant, with
