Mangifera Indica, Linne.* 



The Mango. South-Asia. An evergreen very shady tree, reach- 

 ing 70 feet in height. Can be made to bear its delicious fruit in 

 warm and humid forest-regions to sub-tropic zones. In the Hima- 

 layas its culture for fruit ascends to 3,500 feet just outside the 

 tropics. At Port Curtis, barely within the tropics, it bears copiously 

 [Edgar]. Mango-fruits are now already candied in Queensland 

 [Prof. Shelton], they are also made into jelly and marmalade. Mr. 

 W. Kelleway succeeded in fruiting the Mango even as far south as 

 the Richmond-River, the trees from seeds coining there into bearing 

 within five years. At Bangalore Mangoes up to the weight of 3 Ibs. 

 have been obtained. The Mango-tree is held sacred by the Hindus, 

 and is inextricably connected with many of their mythological 

 legends and folk-lore [Dr. G-. Watt]. Ceremonies are celebrated 

 annually. 



Maoutia Puya, Weddell. 



India, on mountains up to 4,000 feet. It is taller than Boehmeria 

 nivea, and furnishes a similar fibre, which however is not so easily 

 separated. This shrub belongs to a tribe of the Nettle-order not 

 possessing burning acridity. None of the true nettles, such as the 

 Girardinias, nor allied stinging plants, have been recommended in 

 this index, although an exquisite fibre is derived from some, as the 

 writer wishes to guard against the introduction of any burning species, 

 which might possiby become disseminated in a mischievous manner, 

 and then probably could not again be suppressed. 



Manihot Aipi, PohL* 



The Sweet Cassava. Tropical South- America, but traced as far 

 south as the Parana-River. The root is reddish and harmless ; it can 

 therefore be used as a culinary esculent, without any preparation 

 further than boiling, while its starch is also available for tapioca ; it 

 attains exceptionally a length of 2 feet. It is a somewhat woody 

 plant, several feet high, and too important to be left altogether 

 unnoticed on this occasion, although we have no evidence that it will 

 be productive in a temperate clime. Aipi has ligneous tough fibres, 

 stretching along the axis of the tubers, while generally the roots of 

 M. utilissima are free from this central woody substance. Both are 

 thriving as far south as Moreton-Bay. 



Manihot Glazioui, J. Mueller.* 



A native of the Ceara coast-district of Brazil, in latitude about 4, 

 possessing a climate arid for a considerable part of the year. This 

 tree is of a comparatively hardy character, and adapts itself readily 

 to the exigencies of culture [D. Morris] . Thrives well as far south 

 as Durban in Natal [J. M. Wood] and Moreton-Bay [Fred. Turner]. 

 It produces the Ceara-Rubber. Its cultivation is not difficult, and 

 its growth remarkably rapid. It could only be grown in regions free
