1. STAT'ICE, L. MARSH ROSEMARY. (Gr. orarifa, to stop ; be- 

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

 form, limb scarious, 5-nerved, 5-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 circum- 

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

 sile on the 3-bracted branchlet. 



6. Limonium L. Very smooth ; Ivs. oblong-elliptical or oblaneeolatc, acute, 

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

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

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

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

 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-flowered spikelets, more close on tho 

 branchlets, cal. lobes scarcely acute, &c. 



2. ARME'RIA, Willd. THRIFT. Flowers collected in a dense head ; 

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

 o shallow lobes, scarious and plaited; petals, stamens, <fcc., as in Statice. 

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



A. vulgaris Willd. Scape terete, smooth ; Ivs. 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 involucral Ivs. Fls. rose-colored. Jn. Aug. 



2 A. latifolia Willd. Scape solitary, tall ; Ivs. 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. PLUMBA^GO, Tourn. LEADWORT. (Lat. plumbum (lead), a dis- 

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

 caous, glandular, 5-lobcd, 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. Capensis Thunb. St. shrubby, scarcely climbing ; Ivs. oblong entire, 

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

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



2 P. coerulia Kunth. St herbaceous, erect; Ivs. ovate-oblong, acuminate, 

 petiole winged and auriculate at base ; fls. in terminal, loose spikes, blue. U f 

 Peru and Chili. 



4 GONTOLOMON speciosum Boiss. (Statice specioea L.), with white 

 fls., 3 or 4 in each spikelet. 



G. Tartaricum Boiss (S. Tartarica L.), with pink fls., 1 or 2 in a epikelet, 

 both from Russia, are occasionally cultivated. Also
