 hoary. Leaves linear-lanceolate, entire. Bracleas ovate, 

 palmate, with many fpinous teeth. — Native of Spain. Cul- 

 tivated by Miller in 1752, being tolerably hardy, flowering 

 in July and Auguft. The habit of the plant is much like 

 Lavender. IVhorls diftant, four or five in eacli fpike, with 

 a pair of clofe, firm, ribbed, fhortilh braBeas, cut into 

 many fpinous fegments, under every whorl. Caly.x clothed 

 with white cottony down ; its teeth ereft, fpinous, nearly 

 equal. Ccrolla twice as long as the calyx, yellow, white, 

 or pate blue ; both its lips dilated and fpreading.

 V. 2. 68. t. 185. Willd. n. 14. (HyfFopus montana

 cous, fomewhat downy. Leaves linear-fpatulate, entire. 

 Bratteas wedge-lhaped, palmate, fpipous. — Native of Va- 

 lencia. Very nearly akin to the lalt, but faid to be her- 

 baceous, and lefs downy. The flrj-wers appear to be fmaller, 

 and the braSeas are confiderably fo. It may neverthelefs 

 be merely a variety.

 ceolate, fmoiith, nearly entire. Brafteas heart-rtiaped, with 

 fpinous teeth, as long as the calyx. — Native of the moun- 

 tains of Switzerland, Dauphiny, Italy, and the Pyrenees. 

 Cultivated by Gerarde in his garden, and Hill prefcrved in 

 curious or general coUeftions, being a hardy perennial, 

 flowering throughout the fummer and autumn. The Jlcms 

 are fomewhat woody, throwing up many It-afy fquarifh 

 branches, a fpan higii, hairy at the two oppofite fides, in 

 lines crofling each other at every joint. Leaves numerous, 

 oppoflte, ilalked, green, elliptic-lanceolate, two or three of 

 the upper ones only occafionally toothed. Whorls more or 

 lefs c.owded into an ovate or oblong, folitary, terminal 

 fpike, eacli whorl accompanied by two broad, reticulated, 



hairy hraQeas, with tlrong fpinous fcrraturcs. Calyx-teeth 

 long, Ipinnus, ereft, nearly equal. Corolla ilraw-coloured, 

 with ttvo dilated lips, longer than the calyx.

 diftantly toothed. Brafteas ovate, with fpinous teeth, as 



long as the calyx Native of the mountains of Switzerland 



and France. Very nearly refembling the lad in every 

 eliential character, cfpccially the hairy lines on the Jlem, 

 though ufually a larger plant, with more conllantly toothed 

 leaves. The degree of hairincfs on the leaves is fomewhat 

 variable.

fides — Native of mountains in Spain, flowering in June, 

 We received it from the late abbe Cavanilles. The habit 

 of the plant, as v/ell as its inflorejcence and fowers, all feem 

 to agree with the two lalt ; but the (harpnels of the leaves, 

 and their ftiong fpinous teeth, as wll as the more firongly 

 reticulated, and deeply cut, braSeas, indicate an efl'ential 

 difference, confirmed perhaps by the pubefcence of the Jlem, 

 which is generally, thongli fparingly, difi"ufed, not coUefted 

 into two denfe oppofiie lines. The leaves moreover are 

 very ftrongly ribbed. 



17. S. hir/uta. Hairy Procumbent Iron-wort. Linn. 

 Sp. PI. 803. Willd. n. 18. Ait. n. 11. (S. tenia; 

 Cluf Hilt. V. 2. 40. Tetrahit herbariorum ; Lob. Ic. 523. 

 Herba judaica Lobelii ; Ger. Em. 690.) — Leaves oblong, 

 obtufe, Itron^rly toothed. Bratieas with fpinous teeth. 

 Stems haii7 all round, decumbent at the bafe — Native of 

 Spain, Italy, and the foutii of France. — Very much akin 

 to the three la!l in its Jloivers, braHeas, &c. but more hairy. 

 The form and teeth of the leaves agree with fcnrd'wides, a 

 hairy variety of which, we fufpeft, is fomctimes taken fol* 

 the true hirfuta. The latter however appears eilcntir.lly to 

 differ, in having the copionshairinefs ol'\X%Jlem equally dif- 

 perfed all round, not collefted into decuffating hnes. The 

 •whorls vary much in being crowded or remote, and are very 

 hairy. The wooden cut cited above, which is the fame in 

 all the three authors, does not well reprcfent the inflorefcencc, 

 nor dillinguilh the hraBeas from tlie leaves. It feems taken 

 from an axiUary-whurled Ipecie.";, like montana, romana, &c,

 Leaves Halked, elliptical, obtufe, crenate. Whorls crowded. 

 Bra6teas ovate, Ipinous-toothed, imbricated in four rows.- — 

 Native of Peru. It flowered in the gardens of Madrid, in 

 .Tuly. The root is fibrous and perennial. Stems fcarcely a 

 foot high, fquare, flightly hairy. Leaves about two inches 

 long, on ftalks about the fame length ; rough on the 

 upper fide, with hairs proceeding from minute tubercles ; 

 fmooth and fiiining beneath Spike folitary, terminal, about 

 three inches long, quadrangiiLir. Bradeas crowded, in 

 four rows, ovate, acute, rigid, fpreading, belet with ftrong 

 fpinous lerratures. Flowers fix in a whorl, three to each 

 brallea. Calyx with five (lender, iharp, nearly equal teeth. 

 Corolla yelli)wifh-white ; its upper lip entire, lower three- 

 lobed, the middle lobe three-cleft. 



SiDEiuTis, in C.ir,hiiiiig, contains plants of the under- 

 flirubby, and Ihrubby exotic kind, of which the fpecies cul- 

 tivated are, the Canary iron-wort (S. canarienfis) ; the 

 Cretan iron-wort (S. cretita) ; and the fage-leaved irou- 

 wort (S. lyriuca). But there are other fpecies that may 

 be cultivated for the fake of variety. 



Methad of Culture. — Tliefe plants may be increafed by 

 feeds, cuttings, and l.iyer;;. The (eeds tliould be fown in 

 pots in the fpring, plunging ihein in a moderate hot-bed : 

 when the phnts have had fome growth, they fhould be re- 

 moved into leparate fni.ill pots, filled with light mellow 

 mould, being afterwards treated as other Ihrubby green- 

 houfc plant -i. The cuttings and layers may be planted 

 out or l.iid down in tlie fummer feafon, and when fufliciently 

 rooted managed .is the other forts. Alio, the third fort 

 may be increafed by pi inting the flipped heads, either in 

 pots or in a fhady border, to be afterwards removed into 

 pots for pioteftion in the winter in a frame. - 



They afford variety in grcen-houfe coUeftiont, among 

 other evergreen potted plants of fimilar growths.
