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.

The polygamous-seared Goat- Wheat. 



P. parvifdlium Nutt. Gen. I. p. 256. 



Vent. Cels., t. 65. ; and our fig. 1324. 



Spec. Char., $c. Leaves spathulate-linear. Ochreas 

 lanceolate, shorter than the internodes. Flowers in 

 branched racemes, whose rachises are thread-shaped. 

 Styles distinct. (Spreng.^) A diminutive upright shrub. 

 Carolina, in sandy wastes. Height 6 in. to 1 ft. 

 Introduced in 1810. Flowers small, greenish white; 

 July and August. 



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^g. 1324. a is a stamen, 

 b the pistil, and c the bisexual flower. 



T. maritima, a species from North America, was sent 

 to the Horticultural Society by Mr. Douglas, in 1826.

Derivation. According to some, from a privative, and trepko, to nourish ; in allusion to the fruit 

 which, though in form like that of the buck-wheat, is unfit for food; according to others para to 

 athroos auxein, from its coming up quickly from seed, viz. on the eighth day. 



Gen. Char., $c. Calyx inferior, of 4 leaves, in an outer smaller pair, and an
