1294 ARBORETUM AND FRUTICETUM. PART lI. 
Spec. Char., &c. Leaves spathulate-linear. Ochreas lanceolate, shorter than the internodes, Flowers 
in branched racemes, whose rachises are thread-shaped. Styles distinct. A native of dry sandy 
wastes in Carolina. Introduced in 1810, and flowers in July and 
August. (Spreng.) _T.polygamum Spr. differs from T. lanceolatum 
Bieb., especially in the foliowing 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 bi- 
sexual, some female. (Vent.) It is ashrub less than 1 ft. high. Its 
stem is upright, of the thickness of a raven’s quill, cylindrical, and 
bears in its upper part numerous slender ramified branches, that 
are disposed so as to form a bushy head. The stem, branches, and 
branchlets are of a brown colour, and all bear ochreas of this colour, 
and that are striated, membranous at the tip, truncate on one side, 
and end lanceolately on the other. The leaves are spathulate, reflexed, 
glabrous, less than half an inch long, a fourth of their length broad, and 
of a delicate green colour. The flowers are small, of a greenish white 
colour, disposed in racemes that are axillary and terminal; and they 
together give the appearance of a globose panicle. The rachis of the 
raceme bears ochreas. The pedicels have each a joint. (Vent. Cels.) 
We have not seen the plant. In jig. 1163. aisa stamen, 6 the pistil, 
and c the bisexual flower. 
T. pungens Bieb., T. glducum Spr., T. grandijflorum Bieb., are de- 
scribed by botanists, but not yet introduced.

Identification. Schreb, Lin. Gen., No. 612.; Willd. Sp. Pl., 2. p. 248. 
Derivation. According to, some from a privative, and ¢rephd, 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.

Spec. Char.,§c. Some of its branches resemble spines, and this character 
distinguishes it from the other species, A. undulata, and is implied in the 
epithet spindsa. In the following description, most of its characters are 
noted: — A shrub, of about 2ft. high, upright, with 
most of the branches directed upwards, but with some 
horizontal, and some a little deflexed. The horizontal 
and deflexed ones are the shorter, and, when leafless, 
have the appearance of spines. Watson has attributed 
(Dend. Brit.) this to their tips being dead: and the 
case seems to be so. The bark of the year is whitish; 
that of older parts is brown. The foliage is glaucous. 
The flowers are white. The leaves are about half an 
inch long, many less. The disk ovate-acute; the pe- 
tiole short. The flowers are borne a few together 
about the tips of shoots of the year; each is situate 
upon a slender pedicel, that has a joint about or below 
the middle, and arises from the axil of a bractea. The 
calyx is of 4 leaves that are imbricate in estivation. 
The 2 exterior are smaller, opposite, and become re- 
flexed. The 2 interior are opposite, petal-like, hori- 
zontal during the flowering, afterwards approximate to the ovary, which 
is flat, and has one of the approximate sepals against each of its flat 
sides. Stigmas 2, capitate. Stamens connate at the base, into a short 
disk that surrounds the base of the ovary. (Observation, and Willd. Sp. 
Pi., and Wats. Dend. Brit.) Indigenous near the Caspian Sea, and in 
the Levant, and flowering in August. It was introduced in 1732, but 
is rare in collections. There is a fine plant in the arboretum of Messrs.
