CAPE BULBS VARIETIES AND CULTURE. 129 



the flower, but having in most of the species downy leaves ; 

 the treatment in all respects is similar to Ixias or Spar- 

 axis. The species are numerous. The following six are 

 named as types : B. bicolor (blue and white), IB. rubro- 

 cyanea (blue and crimson), B. spathacea (light blue), B. 

 sulphurea (yellow), B. tubata (red and yellow), B. 

 Thuribergii (white and red). 



H^EMAXTHUS. 



A genus allied to the Amaryllis, with bulbs of immense 

 size, producing flowers of all shades from white to crim- 

 son, but rather coarse in outline. Culture same as for the 

 Amaryllis. 



TIGRIDIA, OK TIGER FLOWER. 



This is not a " Cape Bulb," being a native of Mexico, 

 but as it resembles in its habits many of that class we 

 place it here. Like the Gladiolus, successive plantings 

 every two weeks from May to July will give a continuous 

 bloom during the summer months until cut off by frost in 

 autumn. Its treatment in other respects may be that of 

 the Gladiolus, only that greater care is necessary in keep- 

 ing the bulbs in winter. After being dried, put them in 

 some dry place, not too hot, where they will not freeze. 



The Tiger Flower is one of the most beautiful of all bulbs, 

 and although it has been in cultivation for nearly three- 

 quarters of a century, has never been so generally grown 

 as it deserves to be, probably from the difficulty of keep- 

 ing the bulbs in winter. 



Its gaudy, tulip-like flowers are yellow, spotted with 

 crimson, orange, spotted violet red, and varying shades of 

 these colors in the different sorts, 



Tigridia conchiflora. Tigridia lutea. 



Tigridia pavonia. Tigridia violacea.
