DIDTNAMIA. GYMXOSPERMIA. 29 



retrorsely pilose, often scarcely a foot high; leaves remote, 

 ovate-lanceolate, acute, with the nerves parallel to the in- 

 dentions, scarcely more than an inch long and half an inch 

 wide; calix very hispid, and pungently awned, about 

 1-third the length of the corolla; corolla uniformly whitish 

 or reddish, externally covered with soft hairs, about an 

 inch long, tube long and slender, funnelformly inflated 

 above; upper lip arched and crenate; lower lip obtusely 

 3-lobed, lobes rounded, entire, and nearly all equal; palate 

 furnished with 2 distinct teeth. 



A genus of about 8 species, exclusively indigenous to 

 Europe, with the exception of G. hispida of the Cape of 

 Good Hope. 



From the seed of the common species a very useful 

 oil may be expressed. 



402. ^SYNANDRA.f 



Calix 4-cIerf! se.^ments unequal, subulate, 

 connivent to one side. Upper lip of the corolla 

 entire and vaulted; the lower obtusely and un- 

 equally 3-lobed; orifice inflated, naked. Upper 

 pair of anthers cohering, having the 2 attached 

 cells empty; filaments tomentose. 



Perennial? and herbaceous; leaves cordate-ovate, those 

 of the stem sessile and amplexicaule; flowers without 

 bractes, sessile, solitary; calix small, embracing the atten- 

 uated tube of the large corolla which partly resembles 

 that of Melittis Melissophyllum as to size and lobing, while 

 its real affinities are to the genus Lamiunif thougli suffi- 

 ciently distinct. 



S. * grandiflora. 



Descript. Stem usually simple, about a foot high, 

 nearly smooth, irregularly grooved, and partly terete. 

 Leaves a little hirsute on the upper surface, lower ones 

 subpetiolate, those of the stem closely sessile and am- 

 plexicaule, cordate-ovate, acuminate, obtusely dentate, 

 often dilated at the base, diminishing upwards. Flowers 

 often commencing with the second or third pair of leaves, 

 solitary and sessile. Calix about 2 lines long, densely 

 and softly pilose, cleft about half-way down into 4 conni- 



t In alhislon to the adherence of the anthers of the 2 longer 

 stamina which distinguishes this genus from Lamium, Gaieopsis^ 

 and Gakobdolon,
