PART 111. 



Spec. Char., SfC. Leaves spathulatclinear. Ochreas lanceolate, shorter than the intcrnodcs. Flowers 

 in branched racemes, whose rachiscs are thread-shaped. Styles distinct. A native of dry sandy 

 wastes in Carolina. Introduced in 1810, and tlowers in July and 

 August. {Sprenj!.) T. jiol^gamum S//r. differs ft-om T. lanceoUitum 

 fl/VA., 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 bi. 

 sexual, some female, {f'ent.) It is a shrub less than 1 ft. high. Its 

 stem is upright, of the thickness of a raven's quill, cylindrical, and 

 bears in its up))er ])art numerous slender ramified branches, that 

 are dis[>osed 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 lanccolatcly on the other. The leaves are spathulate, reflcxed, 

 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 racliis of the 

 raceme bears ochreas. The pedicels have each a joint, {t'cnt. Cils.) 

 We have not seen the plant. In fig. 11G3. n is a stamen, b the pistil, 

 and c the bisexual flower. ''

Derivation. According to some from a privative, and /rrp/io, to nouri.sh ; in allusion to the fruit, 

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

 at/iroos auxcin, from its coming up quickly from seed, viz. on the eighth day.

Spec. Chnr.,Sfc. Some of its branches resemble spines, and this character 

 distinguishes it from the other species, A. unduliita, and is implied in the 

 epithet spinosa. In the following description, most of its characters are 

 noted: — A shrub, of about 2ft. high, upright, with - | \Hy^ 



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 aestivation. 

 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, whicii 

 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 ]Villd. Sp. 

 PL, and IVals. 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.
