then, owing to the great number of visitors, cross-pollination seems 
much more probable in pleasant weather. 
II. The species of Z77//ium have, so far as know, been studied wit 
reference to their pollination only by Loew, whose meager notes 0 
imported plants are perorded in Pringsheim’s Jahrbiicher, vol. xx, :

Four species are grown in the Botanical "Garden at South Hadley, 
Mass., as nearly as possible under natural conditions, 
1. The very inconspicuous, dull reddish-brown flowers of 7: sessile L 
are erect “in the bosom of the leaves.” The stamens closely Surround 
the stigma. Self-pollination seems inevitable. There is no honey. 
No visitors were seen though the flowers were watched at interval: 
each day during their period of flowering. Loew reports one poll 
eating beetle. 
2. Trillium erectum L. The rather large, brown-red flowers are 
abundant and rather conspicuous in the Massachusetts woods in earl 
spring. Their strong, disagreeable odor may perhaps attract carrion 
loving flies or beetles. Unfortunately I could not watch the flowers i 
the woods and there were only afewin the garden. Stigmas and anth 
stand at nearly the same level, freely exposed in ‘the flower-center

self-pollination seems to be the rule here too.
