plant of ornamental value alone ; but on the present species almost 

 all the praise of B. Madagascar! ensis can also be bestowed, and it 

 is really useful likewise for screening unsightly fences quickly and 

 also for other kinds of hedgings. A similar species from the 

 some geographic region is B. connata (Ruiz and Pavon). 



Suddlea macrostachya, Bentham. 



Mountains of India, from 3,000 to 7,000 feet. Shrub with fra- 

 grant spikes of flowers with yellowish tube, bluish lobes and orange- 

 colored orifice. Highly desirable for aesthetic culture with several 

 congeners. 



Buddlea Madagrascariensis, Lamarck. 



Madagascar, Bourbon and Rodiguez. Of the numerous species 

 of Buddlea the most eligible one for shelter-copses, on account of 

 of its great size and always tidy appearance, as well as vigor and 

 celerity of growth. It is ever-flowering, highly elegant, tolerant 

 to many kinds of soil, bears some frost, and like most congeners is 

 easily propagated from cuttings in the open air. Much frequented 

 by bees. 



Suddlea paniculata, Wallich. (B. crispa, Bentham.) 



Himalayan mountains, at altitudes between 4,000 and 7,300 feet, 

 extending to Ava, Cabool and Beloochistan. Attaining the size of 

 a small tree, resisting* English winters unharmed, merely protected 

 by a wall ; flowering there already from the beginning of February 

 till May, scenting the atmosphere around with fragrance [Sir 

 Will. Hooker]. The trusses of flowers resemble those of the Lilac 

 in shape and color. 



Bursera elemifera, J. Hooker. 



Mexico, up to the temperate plateau. This tree furnishes the 

 Mexican Copal or Elemi. 



Butea frondosa, J. Koenig and Roxburgh. 



The " Dhak or Pulas " of India. This magnificent tree extends 

 to the Himalayan mountains, ascending to elevations of 4,000 feet, 

 and bears some few degrees of frost. Hardy in Australia as far 

 south as Moreton-Bay [Fred. Turner.] It is very rich in a peculiar 

 kind of kino, which according to Muspratt contains up to 73 per 

 cent, of Tannin. From the flowers a beautiful red dye is prepared 

 [P. L. Simmonds]. The lac-insect is also nourished by this tree; 

 and the shellac from it is inferior only to that of Schleichera 

 trijuga ; the third quality comes from Ficus religiosa [Dr. Gr. 

 Watt.] Calcutta exports generally shellac to the value of about a 

 million pounds annually.
