1. STAT'ICE, L. Maksh Eosemart. (Gr. araTi^co, to stop ; be- 

 cause used medicinally it stops dferrlioea, says Pliny.) Calyx funnel- 

 form, limb scarious, 5-nerved, S-parted ; petals scarcely united at base ; 

 filaments 5, adnate to the very base of the corolla ; ovary crowned with 

 the 5 glabrous, filiform styles, utricle regularly or irregularly circnm- 

 scissile. — U Herbs with the scape branching the flowers 3-bracted, ses- 

 sile on the 3-bracted brauchlet. 



S. Limonum L. Tery smooth; lvs. oblong-elUptical or oblanceolate, acute, 

 tipped with a bristle, tapering to a long petiole ; scapes terete, fistulous, bracted, 

 paniculate ; spikelets 1-fiowered (rarely 2), involucrate with 3 bractlets, remotely 

 secund on the branohlets ; cal. lobes very acute. — Salt marshes along the coast, 

 from Newfoundland to S. Car. Scape 6 to 12' high. Lvs. 1' to 18" long, the 

 petioles rather longer. The root is large, ligneous, strongly astringent, much 

 valued in medicine. Jl. — Oct. (S. Carolinianum 'Walt.) — Differs from the Eu- 

 ropean varieties which have mostly 2 to 3-fiowered spikelets, more close on the 

 branchlets, cal. lobes scarcely acute, &c. 



2. ARME^RIA, Willd. Theift. Flowers collected in a dense head ; 

 involucre 3 to many-leaved ; calyx tubular-campanulate, 5-angled, with 

 5 shallow lobes, scarious and plaited ; petals, stamens, &c., as in Statice. — 

 U Lvs. radical, mostly linear. Scape simple, appendaged above. 



A. vulgaris Willd. Scape terete, smooth ; lvs. linear, flat, obtuse ; outer bracts 

 of the invol. ovate-acute, shorter than the sheathing appendage at their base. — A 

 neat and elegant plant, native near the sea-coast, Brit. Am. (Hook.) Often 

 cultivated. Lvs. 3 to 4' by 2 to 3", numerous, crowded. Scape about If high, 

 bearing a singular sheath at top, formed according to Lindley by the adherent 

 bases of involuoral lvs. Pis. rose-colored. Jn. — Aug. 



2 A. latifdiia Willd. Scape solitary, tall ; lvs. very broad, oblong, 5 to 7- 

 veined ; fls. (rose-red) in a large head from a long sheath ; bracts scarious, the 

 outer oblong-lanceolate, acuminate-cuspidate. — f Portugal. 



3. PLUfflBA^GO, Tourn. Lbadwort. (Lat. ^^MWiftttm (lead), a dis- 

 ease of the eyes, which it was reputed to cure. Pliny!) Calyx herba- 

 ceous, glandular, 5-lobed, not enlarged after flowering ; corolla salver- 

 form, tube longer than calyx, limb twisted in aestivation ; anthers 5, 

 linear ; style 1, stigmas 5, filiform ; utricle membranous, mucronate with 

 the persistent style. — Herbs or shrubs. Fls, cyanic, numerous through 

 the season. 



1 P. Cap6nais Thunb. St. shrubby, scarcely climbing ; lvs. oblong entire, 

 glaucous-tuberpular beneath, petiolate ; fls. in short, dense, terminal spikes, pale 

 blue. — \ Cape of Good Hope. Very pretty. Southward it is hardy. 



2 P. OGerftlia Kunth. St herbaceous, erect; lvs. ovate-oblong, acuminate, 

 pelade winged and auriculate at base ; fls. in terminal, loose spikes, blue. — % \ 

 Peru and Cliili. 



4 GONIOLOMON specidsum Boiss. (Statice speciosa L.), with white 

 fls., 3 or 4 in each spikelet. 



G-. ITartirioum Boiss (S. Tartarica L), with pink fls., 1 or 2 in a spikelet, 

 both from Russia, are occasionally cultivated. Also
