subimbricate.

 flowering branches ascending. 



c. Lrs. subtercte 8.

linear 9.

1. vulgaris, Linn. COMMON THYME. Subshrub, erect, 

 6 in. high: sts. sometimes decumbent at base: branches 

 stiff and woody, usually white-pubescent: Ivs. sessile, 

 3-6 lines long, linear- or ovate-lanceolate, fascicled at 

 the axils; floral Ivs. lanceolate, obtuse: floral whorls lax 

 interrupted spikes: fls. small, lilac or purplish, calyx- 

 teeth of upper lip lanceolate, of lower subulate. S. Eu. 

 An old garden plant, being grown as a sweet-herb. 

 The Ivs. and shoots are used for seasoning. It is well to 

 renew the plants from seeds even,' 2 or 3 years. There 

 are varieties with broad and narrow Ivs. 



2. Herba-bar6na, Loisel. Subshrub, much branched, 

 procumbent, glabrous below: flowering branches short ly 

 ascending, 3-5 in. high: Ivs. short-petioled, ovate- 

 lanceolate, acute, base rotundate, viscid-glandular; 

 floral Ivs. rather similar: floral whorls approximate and 

 capitate: fls. purplish; calyx white-pilose and red, 

 glandular, upper lip trifid, lower teeth of calyx subulate 

 and ciliate-barbed; corolla-tube slightly exserted. 

 Corsica. 



3. Chanuedrys, Fries. Subshrub, low, forming a 

 tuft: sts. diffuse, ascending: Ivs. broad-oblong; petioles 

 ciliate; floral-lvs. similar: fls. whorled or capitate, pur- 

 ple; calyx-teeth of upper lip 3, triangular, of lower lip 2, 

 subulate. X. Eu. Similar to T. Serpyllum and by 

 most considered a form of that species, but said to differ 

 in having the Ivs. less narrowed to the petiole and only 

 the petiole ciliate; also the Ivs. are less prominently 

 veined. 



4. Serpyllum, Linn. ; also spelled Serpyttus (T. azori- 

 cus, Lodd. T. hirsutus, Auth. not Bieb. T. mlcans, 



Lowe). MOTHER OF THYME. CREEPING THYME. Per- 

 ennial or subshrubby, cespitose or creeping: sts. wiry, 

 prostrate and rooting below, ascending-erect above, 

 slightly puberulent : Ivs. elliptic, oblong or ovate, obtuse 

 base more or less attenuate, seldom J^in. long, short- 

 petioled: floral-whorls sessile, congested into a head or 

 the lower more or less distant and racemose: fls. minute, 

 lilac or rose; calyx more or less hairy, 2-lipped to the 

 middle, teeth of upper lip triangular, glabrous or ciliate, 

 of lower lip 2, lanceolate-subulate, ciliate; corolla-tube 

 rather included. Temperate parts of Eu., Asia, and X 

 Afr. G.M. 57:807. L.B.C. 16:1530. A common plant 

 in old gardens, prized as an evergreen edging and as cover 

 for rockwork and waste places; also run wild. The Ivs. 

 are sometimes used for seasoning, as are those of T. vul- 

 garis. The nodes are short, making it a very leafy plant. 

 Variable. Var. albus, Hort., is a white-fld. form. Gt. 45, 

 p. 108. Var. argenteus, Hort., is a form with silver varie- 

 gated Ivs. commonly known in the trade as T. citrio- 

 dorus argenteus, Hort. Var. aureus, Hort.. is a form with 

 golden variegated Ivs. growing about 8-12 in. high; 

 usually known in the trade as T. aureus, Hort., or T. 

 citriodorus aureus, Hort.; there is also a minor varia- 

 tion known in the trade as T. Serpyllum aureus mar- 

 ginatus. Var. Chaubfirdii, Boiss. & Heldr., see T. 

 heterotrichus. Var. citrioddrus, Hort., see var. vulgaris. 

 Var. coccineus, Hort. (T. coccineus, Hort.), grows 

 about 1^-3 in. high, has dark green Ivs. and bright 

 crimson fls. Var. lanugtnosus, Hort. (T. lanuginosus, 

 Mill. T. Cham&drys lanuginosus, Hort.), is a low form, 

 about 3 in. high with small roundish Ivs. which are 

 gray-pubescent; a good edging plant. Var. montanus, 

 Benth. (T. montanus, Waldst. & Kit. T. Chamasdrys, 

 Auth., not Fries), is a form with the branchlets more 

 erect and the Ivs. larger than the type. Var. pulchellus, 

 Hort., has the upper part of the calyx and its teeth 

 purple. G.M. 56:83. Var. splendens,* Hort., is a form 

 with brilliant red (according to some bright purplish 

 red) fls. Var. variegatus, Hort., has white- variegated 

 Ivs., possibly the same as var. argenteus. Var. vulgaris, 

 Benth. (T. SerpyUum var. citriodorus, Hort. T. citrio- 

 ddrus, Schreb.). LEMON THYME. Lvs. smaller than the 

 type and strongly veined; the plant has a decided 

 lemon odor. 



5. hirsutus, Bieb. Perennial or subshrub, cespitose 

 and cushioned or procumbent: flowering branches 

 ascending, hoary-pubescent : Ivs. not punctate, sessile 

 or nearly so, linear-subulate, obtuse, both surfaces 

 hoary-tomentose, margin ciliate: fls. closely approxi- 

 mate in an oblong head, rose; calyx reddish, hirsute, 

 2-lipped below the middle, teeth of upper lip lanceolate, 

 acuminate, of lower subulate; corolla-tube included. 

 S. E. Eu. and Caucasus. 



6. pectinatus, Fisch. & Mev. (T. odoraiissimus, Bieb., 

 not Mill.). Perennial, bush-like: young branches slen- 

 der, erect, leafy: Ivs. glandular-punctate, linear-subu- 

 late, obtuse, fascicled at the axils; floral Ivs. similar: 

 fls. pale purple, in heads; calyx equally 2-lipped almost 

 to the middle, teeth of upper lip lanceolate, rather acute, 

 of lower subulate; corolla-tube included. S. Russia and 

 Asia Minor. G.M. 56:82. Gn. 78, p. 134. Very 

 closely related to T. SerpyUum. Strongly fragrant. 



7. heter6trichus, Griseb. Subshrub, 3-6 in. high: 

 branches ascending, puberulent: Ivs. 6-8 lines long, 

 linear-lanceolate, rather obtuse, fascicled in the axils, 

 flat, glabrous; floral Ivs. similar: floral whorls approxi- 

 mate in a head-like raceme : fls. pale violet ; calyx pilose, 

 upper lip trifid to the middle, its segms. lanceolate- 

 acuminate. Greece and Macedonia. G.W. 12, p. 461. 

 Treated by some authors as T. Serpyllum var. Chau- 

 bardii, Boiss. & Heldr. 



8. carnSsus, Boiss. Subshrub, about 9 in. high: sts. 

 decumbent at base, otherwise erect, white-pubescent: 

 Ivs. minute, fascicled, strongly revolute, fleshy, sub- 

 terete, oblong, obtuse, glandular-punctate, glabrous,
