1917] Goodspeed : Notes on Trillium 81 



parted whorl of leaves corresponding in shape and provided with a 

 small undeveloped flower in the center (cf. Goodspeed and Brandt, 

 19166). Within the leaves on the ridge at the top of the stem were 

 a series of five such undeveloped flowers. The leaf measurements show 

 that there were five distinctly larger leaves, and these made up a some- 

 what irregular outer whorl. Some years ago another plant of almost 

 exactly this description was found in the Berkeley Hills, but the 

 rootstock unfortunately was not kept under observation. 



8. Collected in the Berkeley Hills, 1916, by Dr. Brandt ; rootstock 

 in pot 47. This rootstock produced six flowering shoots, five of which 

 were normal throughout. The sixth was again a fasciated shoot with 

 flattened stem bearing two whorls of three leaves each, the leaves of 

 the outer whorl being somewhat the larger. There were also four 

 sepals, all of them f oliaceous ; five petals, nine stamens, three long and 

 six short ; six styles and stigmas, and a single large-celled ovary with 

 six parietal placentae. 



9. Collected in Marin County, 1916; rootstock in pot 11. This 

 plant is figured in plate 12. As will be seen, the rootstock produced 

 two shoots, both of which bore a single four-parted whorl of leaves 

 with an undeveloped flower. The other shoot is arranged on the plan 

 of 5, with ten stamens and a one-celled ovary with five placental 

 surfaces. 



10. Collected in Marin County, 1916; rootstock in pot 45. This 

 rather unusual individual is shown in plate 14, figure 1. Its striking 

 abnormality consists in the condition of the sepals, which are reduced 

 to shriveled, scalelike structures. The petals were, also, of a peculiar 

 shade of yellowish-green, very brilliantly shining, while the ovary was 

 white and the stamens light violet in color. 



The following individuals have been under observation for a year 

 or longer in the garden cultures : 



11. Collected in I\Iarin County, 1911 ; under observation for five 

 years : 



1911 — Rootstock collected with two entirely normal flowering 



shoots. 

 1912 — Two shoots produced. One shoot entirely normal and the 



other bearing four leaves, three sepals, four petals, and 



six stamens, one of which was connected with a petal. 

 1913 to 1916 — One or two entirely normal shoots produced each 



vear.
