to the Australian Donjanthes (see Gard. Chron. July 3, 1910), and has 

 a similar habit. It lived in the narrow border of the Cactus House. 



ZiNGIBERACEAE : 



Cautlea lutea, Himalaya. 

 Hedychium flavescens, Himalaya. 

 H. angustifolium, India. 



H. Gardnerianum, Himalaya, Nepal, Sikkim. i 

 H. Sadlerianum, hybrid. 

 Roscoea purpurea, Himalaya. 

 R. purpurea, var. 

 Zingiber Mioga, Japan. 



All these are very satisfactory on borders against the Tropical Fern 

 House and Palm House. Zingiber Mioga, though well established, has 

 not yet flowered. All the others flower freely and are quite effective. 

 Alpinias are worth trying. 



The following shrubs are grown in a similar position : 



Abutilon vexillarium (Bot. Mag. t. 5717), Trop. America. — This and 

 the variegated form are excellent for plant-house walls, if trained and 

 not allowed to get bushy. 



Berberis Fremonti, Texas and Arizona. — This is said to be hardy, 

 but certainly it benefits by being planted against the Cool Fern 

 House. The shrub is ornamental with glaucous leaves. B. Fortunei I 

 does not succeed in the open, but with slight shelter does well. 



Caesalpinia Gilliesi, South America. — Has succeeded against the 

 wall of the Cactus House. Specimens in flower have been sent me 

 from Devonshire. C. japonica does not succeed in the open, but grows 

 strongly between the Palm House and Tropical Fern House. 



Camellia Sasanqua, Japan and China. — ^The double white growing! 

 against the wall of stove, but not trained close to it, has been exceed- 

 ingly beautiful, flowering freely in late November and early December. 

 The single red has also been ornamental. C. japonica, flowering in) 

 late April, under similar circumstances has also been good. The single 

 red, named * Jubiter, ' has been very handsome. 



Capparis spinosa {Bot. Mag. t. 291), Caper-plant. — The beauty 

 of this plant is known to few. Planted against the wall or corridon 

 it spreads to about 6 feet across in summer, and flowers freely, ii 

 not encroached upon. In winter it dies back and is covered with al 

 light to keep off wet. 



Carpenteria californica. — A well-known Cistus-like shrub allied ti 

 Philadelphus . 



Ceratonia Siliqua, South Europe, Norbh Africa, and the East.— j 

 A small evergreen leguminous tree, suitable for a plant-house wall! 

 Its flowers have no corolla. It is a plant of interest on account o| 

 the value of the pods for feeding purposes. They are probably th| 

 husks mentioned in the Parable of the Prodigal Son. 



Cocculus laurifolius, Himalayas and Japan. — For several years thi 

 has lived in a sheltered corner. It cannot flourish for want of room
