108 BULBS AND TUBEROUS-ROOTED PLANTS. 



they commence to grow, then bring forward into a mod- 

 erately heated house. 



G. concolor (One-colored). This is a desirable 

 species,, if for its color only, which is of a clear bright 

 yellow. It has from two to eight flowers on a one-sided 

 spike. In the evening it emits a fragrance like the 

 common pink. It must be grown in a frame, as its sea- 

 son of flowering will not permit of spring planting, and 

 it is impatient of greenhouse treatment. 



G. cruentus (Bloody). Introduced from Natal 

 in 1868, and is but little known. The flowers are very 

 large, brilliant scarlet, yellowish-white speckled with 

 red at the base of the limb, or borne on spikes from six 

 to ten inches long. 



G. cuspidatus( Sharp-pointed) . This is a remark- 

 able form because of the great length and undulation of 

 the petals. The cream-colored flowers are produced in 

 May, and have the lower petals marked with a bright 

 yellow spot on a rich purple blotch. 



G. c. ventricosus (Swelling). A variety with 

 reddish drooping flowers, with shorter tube and less 

 inflated spathes than -the type. 



G. debilis (Weak). A species bearing solitary 

 flowers, differing from most others of the genus, as all 

 the petals are uniform, spreading open like the Ixias; 

 the flowers are white, with rose-colored spots on the two 

 inner sections. 



G. dracocephalus (Dragon's-head). Introduced 

 in 1871. Flowers yellow, closely striped with dull red- 

 purple, about two inches long and broad, the lower sec- 

 tions bright green, purple spotted. More curious than 

 beautiful. 



G. edulis (Edible). This species is remarkable 

 because of its entire want of beauty. The flowers are 

 white, slightly stained with pink and yellow, and so 

 much curled that they have a withered appearance as
