﻿38 SEEDS AND PLANTS IMPOKTED. 



40511 to 40523— Continued. 



40511. Chrysanthemum caucasicum Pers. Chrysanthemum. 

 A glabrous perennial chrysanthemum. Stems erect, simple or 



sparingly branched; leaves pinnately divided, leaflets linear-subu- 

 late ; flower heads solitary, terminal ; ray flowers white, disk yellow. 



40512. Chrysanthemum coccineum Willd. Chrysanthemum. 

 " Glabrous perennial 1 to 2 feet high ; stem usually unbranched, 



rarely branched at the top; leaves thin, dark green, or in dried 

 specimens dark brown ; involucral scales with a brown margin ; rays 

 white or red, in such shades as pink, carmine, rose, lilac, and crim- 

 son, and sometimes tipped yellow, but never wholly yellow." 

 (Bailey, Standard Cyclopedia of Horticulture, vol. 2, p. 757.) 



40513. Chrysanthemum carinatum Schousboe. 



" Glabrous annual, 2 to 3 feet high ; stem much branched ; leaves 

 rather fleshy, pinnatifid ; flowers in solitary heads which are nearly 

 2 inches across, with typically white rays and a yellow ring at the 

 base; involucral bracts carinate (keeled). The two colors, together 

 with the dark-purple disk, gave rise to the name tricolor. The 

 typical form, introduced into England from Morocco in 1798, was 

 pictured in Curtis's Botanical Magazine, pi. 508, 1799. By 1856 

 signs of doubling appeared. In 185S shades of red in the rays ap- 

 peared in a strain introduced by F. K. Burridge, of Colchester, 

 England, and known as C. burridgeanum Hort. (See Curtis's Bo- 

 tanical Magazine, pi. 5095, which shows a ring of red on the rays, 

 adding a fourth color to this remarkably brilliant and varied flower, 

 and Flore des Serres, vol. 13, pi. 1313, which also shows C. venustum 

 Hort., in which the rays are entirely red, except the original yellow 

 circle at the base.) C. annulatum Hort. is a name for the kinds 

 with circular bands of red, maroon, or purple. C. dunnetti Hort. is 

 another seed-grower's strain. There are full double forms in yellow 

 margined red and white margined red. the flowers 3 inches across. 

 The commonest and gaudiest of annual chrysanthemums, distin- 

 guished by the keeled or ridged scales of involucre and the dark 

 purple disk." (Bailey, Standard Cyclopedia of Horticulture, vol. 2, 

 P. 754.)

40514. A small-flowered iris, 8 to 12 inches high.

 veined with yellow, a dull yellow, or some shade of gray 

 purple." (W. R. Dykes, The Genus Tris, p. 62.)
