296 Select Plants for Industrial Culture and 



Magnolia macrophylla, Michaux. 



Eastern States of North- America. Although not cultivated for 

 any special purposes of the arts or of technics, yet this tree is 

 admitted into this list as one of the grandest of its kind, as well in 

 foliage as flowers. It attains a height of about 60 feet ; its leaves 

 are from 1 to 3^ feet long, while its flowers attain a diameter of 

 fully 1 foot. M. grandiflora, L., attains a height of 100 feet, and a 

 stem diameter of 3 feet on the Mississippi ; it bears the winter of 

 Philadelphia. Most deciduous Magnolias with M. Soulangeana 

 endure the severest winters of Lower Germany [H. Koehler]. M. 

 acuminata, L. and M. Fraseri, Walter, are also large trees. M. 

 acuminata is particularly adapted for street-planting, as it will live 

 in the smoky air of cities. The flowers of all exude much honey- 

 nectar for bees. They ought also to be valuable for perfumeries. 



Maharanga Emodi, A. de Candolle. (Onosma Emodi, Wallich.) 



Nepal. The root produces, like that of Alkanna tinctoria, a red 

 dye. 



Malachra capitata, Linne". 



Tropical America. A tall herb, annual, or of more than one year's 

 duration. Its fibre is obtainable to lengths of 9 feet ; it is of a silky 

 lustre, and equal in technical value to Jute [O'Connor] . 



Mallotus Philippinensis, J. Mueller. (Rottlera tinctoria, Roxburgh.) 



South-Asia, Western Polynesia, and East-Australia, in jungle- 

 country extending into New South Wales. A bush or tree, attaining, 

 according to Mr. P. O'Shanesy, a height of about 60 feet. Though not 

 of great importance, this plant should not be passed on this occasion, 

 inasmuch as the powdery substance, investing the seed-capsules, 

 constitutes the Kamala, which can be employed not only as an orange 

 or red dye, but also as an anthelmintic remedy. The Hindoo silk- 

 dyers produce the colour by boiling the Kamala with carbonate of 

 soda, and use it effectually even for silk goods. 





 Malva crispa, Linne. 



Indigenous probably to South-Western Asia. A tall annual herb. 

 The curled leaves are used extensively in France for dressing 

 desserts, for which purpose the plant is especially grown [Vil- 

 morin]. 



Mammea Americana, Linne. 



Tropical America. This tree is cultivated in Jamaica up to 3,000 

 feet [Fawcett]. Fruit large ; the pulp, except the most outer and 

 most inner, edible.
