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
