anatropous. CAPSULE 2-valved, septicidal. SEEDS minute. EMBEYO straight, albu- 

 minous. 



Biennials, rarely perennials, generally cottony or woolly, with watery often 

 mucilaginous juice. LEAVES alternate, often decurrent, exstipulate. FLOWERS $ , 

 a little irregular, fascicled, rarely solitary, in simple or branching spiciform racemes. 

 CALYX monosepalous, 5-partite, persistent. COROLLA hypogynous, inonopetalous, 

 isostemonous, sub-rotate; limb 5-partite, caducous, aestivation imbricate. STAMENS 

 5, inserted on the corolla-tube, and alternate with its lobes ; filaments unequal ; 

 anthers fixed by the middle, or throughout their length, of 2 confluent cells. OVARY 

 with 2 antero-posterior cells, placentae on the septum ; style undivided, dilated at 

 the top ; stigma simple or bilobed ; ovules numerous, anatropous. CAPSULE 2-celled, 

 septicidally 2-valved, valves bifid at the top. SEEDS minute, rugose. EMBRYO 

 straight, in the axis of a fleshy thick albumen. 



PRINCIPAL GENERA. 

 Verbascuni. Celsia, &c. 



This little order, mainly composed of the genus Terbascum (Mullein), agrees with Solanea in its 

 isostemonous corolla, and with Scrophularinece in its straight embryo. The Mulleins inhabit the tem- 

 perate regions of the Old World. 



Some indigenous species ( V. Thapsus and phlomoidfi) contain a bitter astringent principle in their 

 leaves and a mucous principle in their flowers, combined with a little volatile oil of a sweet taste, 

 whence their use as bechics and sedatives. [Their seeds are used to poison mice and to stupefy fish.]
