after the flowering become more entirely rosy. The pedicels, erect while 
bearing the flower, after the flowering become deflexed, and render the fruit 
pendulous. The plant forms a hemispherical bush 2 or 3 feet high ; which, 
during great part of July and August, is covered with its beautiful white 
flowers, tinged with pink; and forms a truly admirable object. It thrives 
best in peat soil, and is worthy of a prominent place in the most select 
collections of shrubs.

T. polygamum Spr. differs from T. lanceolatum 
Bieb., especially in the following points: stem very 
much branched ; leaf spathulate ; sexes polygamous ; 
sepals expanded during the flowering ; and ochreas 
entire at the top. The polygamous condition of the 
sexes consists in the flowers of the same plant being 
some bisexual, some female. In fig. 1324. a is a stamen, 
6 the pistil, and c the bisexual flower.
