yellow at the base of the three lower." The color as shown in the color 

 plate in Flore des Serres (Van Houtte, 1873) shows yellow blotches bordered 

 with white, which contrast with the bright color. The flowers of G. Col- 

 villei are fragrant, which points to G. tristis or G. tn'stis var. concolor as 

 one of the parents. 



The white variety of G. Golvillei seems to have been discovered about 

 1872. It is said to have appeared as a sport in two horticultural estab- 

 lishments in Holland in the same year. It was figured, together with 

 G. Cohillei, in Flore des Serres (Van Houtte. 1873). The plate shows 

 a pure white variety with yellow lanceolate blotches on the lower segments. 

 This sport, known as G. Cohillei albus. had colored anthers and was sup- 

 planted later by the variety -n-ith white anthers known commercially as 

 G. Cok-illei The Bride. 



G. Colvillioid^s, a hybrid produced by crossing a variety of G. Lenioinei 

 with G. angustus (the latter a form closely related to G. tristis), resembles 

 G. Cohillei but has yellow flowers. The leaves are long and straight, with 

 prominent ribs. The stems are slender and erect, and bear medium-sized 

 flowers. The color is a pure chrome yellow, \s-ith three triangular black 

 spots or blotches. The normal time of flowering is the early part of July, 

 but if the conns are planted in the autumn and protected during the 

 winter by glass frames they may be made to flower with G. Cohillei. 

 This hybrid was originated by Lemoine and was offered as a novelt}- in 

 the autumn of 1903. 



G. delicahis is a hybrid between G. rcaircus and G. hlandus, raised by 

 Dean Herbert. 



G. dracocephalus has long been known, but sesms not to have been 

 employed in hybridizing until recent years. Jackson (1889) described 

 the dracocephalus-gandavensis hybrids of C. Sander as being of great 

 size, strong, and floriferous. He states that a large proportion bear 

 flowers entirely free from the stripes in the lower petals common to 

 G. gandavensis. This is due to the dracocephalus blood and is a 

 step toward self-color. "UTiether these hybrids were introduced is 

 unknown. 



The veteran hybridizer. Lemoine. offered his dracocephalus hybrids in 

 1900. These were produced by crossing G. dracocephalus and some of the 

 varieties of G. Lemoinei. The form of the flowers indicates their origin, 

 while the singular spots, or macules, produce a striking eftect. The first 

 varieties sent out were Cheret. Forain. Leonnee. Luc-OHvier Merson, 

 Paul Baudn.-. and Roty. Since 1900 other varieties have appeared each 

 year. A list of these varieties, together with the dates of their introduction, 

 follows :
