axils of the upper leaves, a woolly peduncles develop enring 
globose clusters of age twelve short-pedicelled flowers. The 
flower has a silky yel Tee campanulate calyx and corolla, 
each with five erect pee those of the calyx being short, triangular, 
and acute, those of the corolla longer, lanceolate, and reddish- 
tipped. The inconspicuous pistil is surrounded by the mass of 
stamens, which are one to two inches long, with small anthers, and 
bright red glossy filaments. The fruit is a ee — woody 
pod, with hairy sides and conspicuously thickened edges 
The genus Anneslia was first described ‘ Salisbury in his 
Paradisus Londinensis in 1807, and later as Calliandra by Bentham 
in 1840, to include certain species of mimosa-like plants readily 
distinguished from Inga, Acacia, and related genera. It now in- 
cludes about one hundred species growing in the American tropics. 
Anneslia Tweedici is a native of Brazil, Argentina and Uruguay, 
where it was found growing on hillsides by the collector for whom it 
was named, James Tweedie. He was a Scotch landscape gardener 
who botanized in these countries between 1825 and 1845. The 
first cultivated plants were raised from seeds sent by Tweedie 
to the Botanical Garden at Glasnevin, Ireland, in 1843. 
Plants of Anneslia Tweediei have been grown in the greenhouses 
of the New York Botanical Garden since 1901. The particular 
plant from which the illustration was made is now nearly ibe ae 
high, is of a spreading rather bushy habit, and blooms ago 6 : 
long season each winter. Its attractiveness lies almost wholly 
the beautiful clusters of stamens. KENNETH R. BOYNTON.
