Cyrtanthus sanguineus Hook. (Amaryllidaceaé) is one of the 
37 species credited to the genus. It was first figured in the Botan- 
ical Magazine (1), and was copied by Pax (2) in his monograph of 
the family. The genus is restricted to South Africa. C. sanguineus 
and two other species were procured by Dr. C. J. CHAMBERLAIN 
from the Botanical Garden at Durban, a garden which, like most 
of those of the colonies, is supported by the nursery trade. The 
plants are not raised from seed in the garden, but are brought there 
after being dug up from places in which they grow naturally. The 
plants secured by Dr. CHAMBERLAIN have been growing in the 
greenhouses of the University of Chicago. The first blossoms 
appeared in the winter of 1912-1913.. They were hand-pollinated, 
and from the ovaries and embryos thus derived the present study 
was made. 
Cyrianthus sanguineus has a tunicated bulb about two inches 
in diameter. The leaves are thick and leathery, of a bright green 
color, and about a foot long. The epigynous flower is 3-4 inches 
in length, and of a rich coral color, almost crimson. The perianth 
tube is either suberect or decidedly curved, and the upper half of 
its throat is about one inch in diameter. The stamens are UNF 
seriate and slightly exserted; the filaments are incurved and the 
anthers are oblong. The ovary is 18 cm. long and 6 cm. in diameter. 
The ovules are campylotropous. In an ovary of about 12 ovules 
only 6 or 7 develop to maturity.

The material was taken at different ages, killed in chromacetic 
fluid, and the sections stained in safranin and gentian. All the 
drawings were made with the help of an Abbé camera lucida.
