2 DIANDRIA — MONOCxYNIA. IVeronica. 



Wilson observes that the central flower (of the e7'ect var. at least) lias 

 two stamens, one placed below, the other above, the iatcrally-coni- 

 presscd mermen ; and that the side-flowers have only otie, placed above 

 the germcn. 



2. S. radicans, Sm. (creeping Glassivort); stem woody pro- 

 cumbent and rooting-, articulations compressed spreading and 

 notched at the top, spikes oblong obtuse. E. Hot. t. 1G91, c^- t. 

 2467, {S. fruticosct). 



Muddy sea-shores, rare ; on the Norfolk and Sussex coasts. In the 

 Lslfi of Sheppey, Kent. Near Newry, Ireland. FL Aug. Sept. If . 

 — This scarcely differs from the preceding', except in its more branching", 

 straggling and percimial stem, fpiite woody Ijelow, often growing at the 

 e(\ge of a low muddy bank, and depending from it. The trne »S. fruti- 

 cosa is a very different plant, and confined to the south of Europe and 

 north of Africa. — The various species of this genus, as well as others 

 belonging to the same natural family, and growing abundantly on the 

 coasts in the south of Europe and north of Africa, yield a vast quantity 

 of soda, so much employed in making both soap and glass ; whence their 

 EngHsh name, Glasswort. 



2. HipPURis. Li7in. JNLire's Tail. 



1. n. viilgnris, L. {common Mare s- Tail); leaves linear 6 — 8 

 or 10 in a wliorl. E. Bot. t. 763. 



Ditches and, usually, stagnant waters ; less frequent in Scotland. 

 FL Juno, Jul3^ 1/. — Steui erect, simple, jointed. Whorls of about 

 8 haves, which are callous at the point. Flowers at the base of each 

 of the upper leaves, not unfrequently destitute of stamen. Germen oval, 

 inferior ; within its minute rim or border, at the summit, which consti- 

 tutes the calyx, is situated the statnen, with its large two-lobed anther ; 

 ■when young, having the style passing between the two lobes. Seed 

 fixed to the top of the cell of the pericarp, and thus inverted. In deep 

 streams of water this plant attains to 2 or 3 feet, wiih the leaves exces- 

 sively crov.ded, 3 and even 4 inches in length, pellucid, with an opaque 

 nerve, their points not callous ; the wliole plant submerged and barren.
