1. A. sessilis, Br.; Moq. in DC. Prod. xiii. part ii. 357 ; Wight, Ic. 

 t. 727. A prostrate brandling glabrous or slightly pubescent annual, extend- 

 ing sometimes to 2 ft. or more. Leaves narrow, oblong-lanceolate, or rarely 

 nearly obovate, about 1 in. long, tapering at the base. Flowers white, scari- 

 ous and shining, in axillary clusters, surrounded by a few short woolly hairs. 

 Perianth- segments about 1 line long, rather acute, but not pungent, longer 

 than the otherwise similar bracts. Stamens very short, 3 only, without inter- 

 vening teeth or appendages. — Telanthera polygonoides, Seem. Bot. Her. 407, 

 not of Moq. 



On roadsides and in waste places, Hance ; also Wright. Common in tropical and sub- 

 tropical Asia, Africa, and America. In Hance's specimen the internodes are shorter than 

 usual, and the flower-clusters more abundant and conspicuous. It is not, however, the A. 

 ?, which has much longer sepals, the outer ones pungent, and 5 fertile stamens. 



Order LXXXVIIL POLYGONACE^J. 



Perianth of 6, 5 or fewer segments, regular and equal, or the inner ones 

 enlarged. Stamens variable in number, usually 9, 8, or 6. Ovary free, with 

 a single erect ovule. Styles or stigmas 2, 3, or rarely more. Fruit a small 

 seed-like nut, usually with as many angles as styles, enclosed in or scarcely pro- 

 truding from the persistent perianth. Embryo straight or curved, in a mealy 

 albumen. — Herbs or rarely shrubs. Leaves alternate. Stipules usually thin 

 and scarious, rarely herbaceous, forming a sheath or ring round the stem within 

 the petiole. Flowers small, herbaceous or sometimes coloured, clustered in 

 the axils of the leaves, or in spikes or racemes forming terminal panicles. 



A considerable Order, dispersed over every part of the globe. 



Fruiting perianth of 6 segments, the 3 inner ones enlarged 1. Rumex. 



Fruiting perianth of 5 nearly equal segments 2 Polygonum. 



1. RUMEX, Linn. 

 Perianth-segments 6, the 3 inner ones enlarged after flowering, and closing 

 over the triangular nut. Stamens 6. Styles 3, very short, with fringed stig- 

 mas. Herbs or rarely shrubs. Flowers numerous, small, herbaceous, but 

 often turning red, usually pedicellate, in whorl-like clusters, axillary, or in 

 terminal simple or paniculate racemes. 



A considerable genus, widely distributed over most parts of the globe, but more especially 

 in temperate regions. 



1. R. crispus, Linn.; Meisn. in DC. Prod.xiv. 44. A perennial, with a 

 thick root -stock, and erect furrowed stems 2 to 3 ft. high ; the branches few 

 and short. Kadical leaves narrow, usually 6 to 8 in. long, much waved and 

 crisped at the edges, the upper ones smaller, passing gradually into bracts. 

 Stipules sheathing, ragged at the edges. Whorls of flowers numerous, and 

 when in fruit much crowded in a long narrow panicle. Inner segments of 

 the fruiting perianth broadly ovate, 2 to 3 lines long, with a coloured grain 

 or tubercle on the midrib. 



Roadsides at Say wan, Champion ; also Hance. Common in Europe and temperate Asia, 

 and now naturalized in many other parts of the globe. The Chinese specimens, like all those 

 grown in warm or dry climates, have tubercles on all the inner perianth-segments. More 

 northern specimens have them frequently on one segment only of each perianth.
