As just stated, some varieties (as, Caprice, Her 

 Majesty) multiply more rapidly than others (as, pallida 

 Dalmatica). As an instance of rapid multiplication: 

 A seed sowed by Mr. J. Marion Shull, Chevy Chase, 

 Md., in October 1915, produced in 1916 a plant (sub- 

 sequently named "Virginia Moore") which in 1917 

 sent up a flower-stem. In 1918 the clump sent up 

 eighteen flower-stems, and shortly after blooming was 

 divided into over forty separate plants for propagation. 

 These plants in 1919 gave forty bloom-stems and by 

 the spring of 1921 the number of stems ran to two 

 hundred and twenty-five, carrying up to twelve flowers 

 to a stem, and the entire period of bloom was twenty- 

 six days. Shortly after blooming, four hundred plants 

 were taken for distribution. (See also under Propa- 

 gation in Chapter IX.) 



In respect to size, the habit of growth of different 

 varieties is not uniform. An ordinary full-grown 

 rhizome of some varieties (as, pallida Dalmatica, 

 Lent A. Williamson) is four or five times larger than
