plant growing on rocks and sometimes on the stems of trees on the 

 Organ Mountains of Brazil/' It has long, bamboo-like, branching 

 stems, and appears to be more suitable for growing into large plants 

 for outdoor purposes than for the greenhouse. The leaves are about 

 six inches long, oblong, angular, with wavy red margins. The flower 

 stems are axillary, branched, and drooping, bearing numerous coral- 

 red flowers. The females are more attractive, owing to the length 

 and rich color of the ovary. The flowers are very persistent and 

 exceedingly ornamental. In the Botanic Gardens at Kouen it is used 

 to cover the walls. At the home of Mr. Cameron, at Niagara Falls, 

 the writer has seen a large plant, eleven feet high and profusely 

 branched, growing in the center of the lawn, laden with its beautiful 

 bright-red blossoms, which had an exceedingly picturesque effect, 



Bismarcki. Bismarcki, President Carnot, Souvenir de F. Gaulin, 

 and Otto Forster are said to be crosses between the two last-named 

 species, but are disliked by florists because of their leggy appearance. 

 They are all very similar in habit, and resemble very closely B. Teii*~ 

 cheri, the female clusters producing a gorgeous display of red. 



Incarnata; Insignis. B. incarnata, Link and Otto (B. insignis, Gra- 

 ham), is one of the oldest and most variable species, and includes ;i 

 number of named kinds seldom seen in cultivation now, such as acumi- 

 nata, ancubaefolia, papillosa, Lindleyana, maculosa, and purpurea. It is 

 said to have been introduced from Mexico to the Berlin Botanical Gar- 

 dens in 1822. The plant is about two feet high, with somewhat 

 lanceolate, toothed leaves, which are green above and reddish beneath. 

 The flowers are rose-colored, and hang in clusters on arching flower 

 stems. It is a very handsome decorative plant, but has been almost 

 entirely supplanted by incarnata grandiflora, a much improved vari- 

 ety, which is very useful for cut flowers for decoration in winter. 



Foliosa. B. foliosa, H. B. K., was introduced from New Granada 

 by William Sanders in 1868. It sends up from its base numerous 

 frond-like branching stems, which are densely clothed with very small, 

 glossy, green leaves. The flowers are small, white, tinged with rose. 

 This is a very ornamental species at all stages of its growth. 



Scandens. B. scandens, Swartz, as already mentioned, is one of 

 the most widely-distributed begonias known, being a native of Ja- 

 maica, Guiana, Peru, and Costa Eica. It was introduced into culti- 

 vation about 1874 from the West Indies. The stems climb, trail, or 

 cling, by means of short aerial roots, like ivy. The leaves are about 

 four inches long and glossy green. The flowers are small, white, 

 and hang in ball-like clusters. 



GlaucopJiylla. B. glaucophylla, Hook., is much more frequently 

 met with in cultivation than the last named, and goes by the follow-
