106 MISSOURI BOTANICAL GARDEN BULLETIN 



The origin and species of this Ricinus is not known, a solitary 

 plant appearing in the Garden in 1920. The small seeds, 

 measuring 3/8 of an inch long and 3/16 of an inch wide, 

 are produced in abundance, the flowers appearing when the 

 plants are only two feet tall. This castor bean grows to a 

 height of six feet, the leaves measuring six to twelve inches 

 across. The green leaves and seed pods and the glaucous 

 stalks give this entire plant a gray-green appearance. This 

 is a valuable Ricinus for garden planting where tropical 

 effects are desired. It is a rapid grower, branches freely, 

 and, unlike the taller sorts, retains its basal foliage, making 

 it a good subject for use either as a background or for plant- 

 ing in the fore part of a bed. 



The "Blue Lace Flower," Trachymene caerulea, was a 

 pretty little flower while it lasted. The plants grew well, 

 attained a height of a foot, and each bore a number of flowers. 

 Immediately after flowering, however, all died without ripen- 

 ing any seed, the climatic conditions being too severe for such 

 a delicate plant. 



Verbena hybrida var. grandiflora "Ellen Willmott" and 

 "New Giant-flowered Mixed" w^ere both excellent bloomers. 



During the summer of 1922 it is proposed to give cannas. 

 delphiniums, and peonies a leading place in the test garden.
