1 T. SPICA'TA (Lin. spec. 795.) h . F. Native of the region 

 of the Mediterranean, on dry hills, among heath ; as of Achaia, 

 Melos, Samos, Cyprus, Candia ; Asia Minor, about Smyrna, and 

 of Palestine. Sibth. et Smith, fl. grace. 6. p. 37. t. 546. T.

 281. t. 1230. Plukn. phyt. t. 116. f. 5. A stiff, hard, procum- 

 bent shrub, with ascending hardly pubescent branches. Leaves 

 of the sterile branches small, decussate, obtuse ; those of the 

 fertile branches an inch long, linear, acute, stiff, flat or compli- 

 cate, ciliated. Whorls many-flowered, disposed in spikes, which 

 are sometimes interrupted. Floral leaves and bracteas broad- 

 lanceolate, acute, coloured, ciliated, and closely imbricated with 

 the flowers, and covering the calyxes. Calyx glabrous or 

 ciliated on the nerves. Corolla purple. 



Spicate- flowered Thymbra. Fl. June, July. Clt. 1699. Shrub 

 ^ to 1 foot. 



Cult. This is a plant well fitted for rockwork, or to be grown 

 in pots among other Alpine plants. A poor stony or gravelly 

 soil suits it best ; for in no other soil will it survive our winter 

 without shelter. The plant is readily propagated by young 

 cuttings and by seed. 



LIV. DICERA NDRA (from ac, dit, twice, wpac, keras, a 

 horn, and arrtp ai-lpoc, aner andros, a male ; the anthers are 2- 

 horned, each of the cells being spurred at top.) Benth. in bot. 

 reg. vol. 15. lab. p. 413. Ceranthera, Elliott, bot. car. 2. p. 93. 

 but not of Beauv. 



LIN. SYST. Didynamia, Gymnotpernua. Calyx about 13-nerved, 

 tubular, striated, bilabiate ; upper lip spreading, entire, or shortly 



tridentate ; lower lip bifid ; throat pilose inside. Corolla bilabi- 

 ate, with an exserted, straight tube, which is naked inside. Sta- 

 mens 4, didynamous, ascending, approximate : lower ones the 

 longest ; anthers 2-celled : cells divaricate, spurred at top : 

 spurs in both cells equal, straight, acute, and length of the cells. 

 Style villous, bifid at top ; lobes subulate, equal, stigmatiferous 

 at top. This genus is readily distinguished by the form of the 

 anthers.

 tween the rivers Flint and Chatahouchie, Elliott. Ceranthera 

 linearifolia, Elliott, L c. Habit of the narrow-leaved variety of 

 hyssop. Stems erect, twiggy, pubescent. Leaves sessile, nar- 

 row, ^ to 1 inch long, quite entire, glabrous, fascicled in the 

 axils. Whorls 6-flowered. Corolla twice as long as the calyx, 

 downy.

 gyne, a female ; in reference to the villous style.) Benth. lab. 

 p. 414. 



LIN. SYST. Didynamia, Gymnospermia. Calyx about 13-nerved, 

 campanulate, striated ; teeth straight, lanceolate, the 2 lower 

 ones twice as long as the 3 upper ones ; throat naked inside, 

 Corolla bilabiate ; tube exserted, straight, naked inside ; upper 

 lip erect, flatfish, entire ; lower lip spreading, trifid, with flat en- 

 tire lobes. Stamens 4, didynamous, ascending, approximate at 

 apex, lower 2 the longest ; anthers 2-celled : cells parallel, dis- 

 tinct, mutic. Style villous, bifid at apex ; lobes subulate, equal, 

 stigmatiferous at top. Herbs. Whorls densely spicate at the 

 tops of the branches. Floral leaves, bracteas, and calyxes cili- 

 ated with long white hairs. 



1 P. DOCGLA'SII (Benth. lab. p. 414.) floral leaves and brac- 

 teas exceeding the flowers ; stamens shorter than the corolla ; 

 lower calycine teeth more than twice as long as the tube. 1^ . ? 

 F. Native of North California, Douglas. Stems a little branch- 

 ed, quite glabrous. Leaves petiolate, 1 to Ij inch long, oblong, 

 obtuse, quite entire, green, glabrous. Corolla purplish ? ; throat 

 pilose inside. 



Douglas's Pogogyne. PI. 1 foot. 



2 P. MULTIFLOKA (Benth. lab. p. 414.) floral leaves and 

 bracteas shorter than the corollas ; stamens exserted. Tf. . ? F. 

 Native of North California, Douglas. This differs from P. 

 Douglasii, in the stem being divaricately branched ; in the 

 spikes being smaller, and more numerous ; and in the flowers 

 being smaller. Lower calycine teeth hardly twice as long as 

 the tube. 



Many-Jloifered Pogogyne. P). 1 foot. ? 



3 P. PARVIFLORA (Benth. lab. p. 414.) floral leaves exceed- 

 ing the flowers ; stamens shorter than the corolla ; lower caly- 

 cine teeth hardly longer than the tube. If. . I F. Native of 

 North California, Douglas. Allied to P. Douglatii ; but the 

 spikes are hardly an inch long; the leaves narrower and smaller, 

 and the flowers one half smaller.
