 narrowed at the base : floral ones similar to the others ; whorls 

 all distinct, axillary ; calyx very pilose, hispid ; corolla twice as 

 long as the calyx. C H. Native of Tauria, in dry gravelly 

 places ; Arabia and Persia. Corollas reddish purple. Very 

 like Z. tenu'wr, but differs in the corollas being as large as those 

 of Thymus alpinus.

9 Z. JAVA'SICA (Blum, bijdr. p. 822.) flowers capitately spi- 

 cate, terminal ; bracteas subulate, ciliated ; calyxes villous ; 

 leaves petiolate, ovate, erosely and coarsely serrated, clothed 

 with prostrate pubescence on both surfaces. 0. ? H. Native 

 of Java, in the province of Cheribon, on the top of the burning 

 Mount Tjerimai. Upper lip of corolla reflexed, entire : lower 

 one 3-lobed. Stamens 2, hardly exserted. Stigma unequally 

 bifid. 



Jata Ziziphora. PI. ? 



N.B. Z. Ihymoides of Roam, et Schultes, is an imaginary 

 species. 



Cult. The perennial species of Ziziphora are very pretty 

 rock plants. They should be grown either on rockwork, or in 

 small pots well drained with sherds, in any light sandy soil ; 

 they are readily increased by seeds and cuttings. The seeds of 

 annual species only require to be sown in the open ground, in 

 April, where they are intended to remain.

LIK. SYST. Didynamia, Gymnotpernua. Calyx campanu- 

 late, bilabiate ; upper lip tridentate ; lower lip bifid. Corolla 

 with an exserted tube, which is furnished with a pilose ring in- 

 side, an elongated widened throat, and a sub-bilabiate limb; 

 the upper lip truncate, emarginate : the lower lip 3-lobed, with 

 broad, short, rounded segments. Stamens 4, all fertile, ascend- 

 ing, didynamous : lower ones the longest ; anthers cohering by 

 pairs, linear, with divaricate cells. Style shortly bifid at apex : 

 lobes subulate ; stigmas mi- 

 nute. Achenia smoothish. A 

 tufted perennial herb, with nu- 

 merous radical leaves, simple, 

 almost naked stems, and pur- 

 plish blue flowers.

small, sessile, crenated leaves. Whorls distant, 6-flowered, 

 secund. Floral leaves bractea-formed, shorter than the ca- 

 lyxes. Flowers on short pedicels, nutant. Calyx 13-nerved, 

 often coloured at top, glabrous or hispid on the nerves ; lips 

 spreading : teeth acute. Corolla bluish purple, 9-10 lines 

 long (fig. 78.) 



Pyrenean Horminum. Fl. June, July. Clt. 1820. PL J to

Cult. This is a very elegant plant when in blossom. It will 

 grow in the open border, and is readily increased by dividing at 

 the root, or by seed. In severe winters it is sometimes liable to 

 be killed by damp ; therefore a reserve plant or two should be 

 grown in pots, so that they may be protected by placing them 

 under a frame in winter. 



Tribe IV. 



SATUREI'NEJi (so called from containing genera agreeing 

 with Satureia in the characters given below.) Benth. lab. p. 

 324. Calyx 5-toothed, equal or bilabiate, with the upper lip 

 tridentate, and the lower one bifid. Tube of corolla exannulate 

 inside, shorter, or scarcely longer than the imbricate calyx and 

 bracteas ; limb of corolla sub-bilabiate : upper lip flat, entire, or 

 eroarginately bifid : lower lip spreading, trifid, with flat, nearly 

 equal lobes ; or the middle lobe is rather the broadest. Stamens 

 distant, straight, diverging, or scarcely ascending, equal, or the 

 upper ones are shorter or abortive. The tetrandrous genera of 

 this tribe are intermediate between tribe Menthoidca and Melit- 

 tinece ; but the corolla is more decidedly bilabiate than in the for- 

 mer tribe ; and the stamens are seldom ascending, as in the lat- 

 ter ; from most genera of which they are also distinguished by 

 the shortness of the tube of the corolla. The diandrous genus 

 Cunila connects tribe Mondrdeae with Melifstxece. 



XXXVI. BYSTROPO V GON (from pvu, byo, to close ; and 

 ruyuy, pogon, a beard ; the throat of the calyx is closed by 

 villi inside.) Benth. lab. p. 324. Bystropdgon species, Lher. 

 sert. angl. 19. 



LIN. STST. Didynamia, Gymnotpermia. Calyx 10- 13-nerved, 

 cam pan ul ate or tubular, equal, 5-toothed ; throat villous inside. 

 Corolla with an inclosed tube, and sub-bilabiate limb ; upper lip 

 erectish, bifid ; lower lip spreading, trifid : lobes all flat and 

 entire. Stamens 4, erect, distant, shorter than the corolla, didy- 

 namous : lower ones the longest ; filaments glabrous ; anthers 

 2-celled : cells parallel. Disk equal, glandless. Style shortly 

 bifid at apex : lobes nearly equal, linear, a little thickened, ob- 

 tuse, stigmatiferous at top. Achenia dry, smooth. Shrubs. 

 Flowers small, cymose in the first section ; the cymes dichoto- 

 mous, subcorymbose, or panicled ; in the second section, dis- 

 posed in dense spicate whorls. Bracteas lanceolate or subulate. 

 This genus is scarcely distinct from Menlha. 



SECT. I. BYSTROPOGON (see genus for derivation.) Benth. 

 lab. p. 325. Calyx campanulate, 10-nerved. Flowers loosely 

 cymose.

 side, pale purple. ?
