Mammillaria 





Mandevilla 



cuttings ; the latter should be kept rather dry at 

 first, or they will damp off. 



Soil. A fairly dry and porous soil is needed for 

 Muiuinillarias generally. Most of them grow 

 naturally in limestone districts, and thus a mix- 

 ture uf two parts sandy loam, one part lime rubble 

 and one part crushed bricks or finely broken pots, 

 will be found suitable for almost all. 



Other Cultural Points. Special hints have 

 already been given under CACTUS as to the treat- 

 ment of succulent plants. These may be applied 

 to Mauimillarias equally as well as to Echino- 

 cacti, Phyllocacti, etc. Most of the plants 

 can be grown in a dry, warm greenhouse, fully 

 exposed to the sun's rays. If they ca be stood 

 upon shelves, and near to the light, so much the 

 better ; this will economise space at the same time. 

 Elongata and its varieties are specially suitable for 

 window culture, being small and slow growing. 

 Macrotuele is nearly hardy, and will do well in a 

 cold frame if protected from damp. Vivipara is 

 quite hardy, but should be given a dry, sunny 

 spot. Such species as pusilla and tuberculosa 

 may be grown in an ordinary cold frame all the 

 summer, but should be wintered in a warm green- 

 house, damp being more fatal than cold. All 

 Mammillarias should be kept drier at the root 

 than ordinary plants. A fair quantity of water is 

 required during the summer, but in winter little 

 will be needed for weeks together. To keep the 

 soil wet is the quickest way to kill the plants, 

 particularly in the case of such beautiful, but 

 tender, species as macromeris and Ottonis. All 

 pots and pans should be iilled half full of drainage 

 crocks, and the soil must be made firm about the 

 roots by means of a rammer, or the plants will 

 not be able to support their own weight.

MANDEVILLA (tyn. AMBLYANTHERA). 



Tall, climbing shrubs (ord. Apocynacese) requir- 

 ing stove heat. The flowers of many of the species 

 are large and showy, but as yet, sauveolens, summer, 

 large, white, fragrant, is probably the only member 

 of the genus familiar to cultivators. Cuttings of 

 the stiff side shoots may be rooted in sand. Soil, 

 good loam and fibrous peat, with sand. The plants 

 do best when growing in a prepared border. For 

 training to rafters and pillars in the stove, suaveo- 

 lens is worthy of note (seep. 50). 



Mammoth Tree (see Sequoia gigantea). 

 Manabea (see jKyiphila). 

 Mandarin Orange (nee Citrus nobilis).
