a thin, powdery woolliness and yellow (sometimes white) flowers, in a 

 pyramidal panicle. It is said to hybridize or cross-breed with the com- 

 mon Mullein, thus producing some remarkable varieties. 



2. LINA'KIA, Tournef. Toad-flax. 



[Latin, Linum, flax ; from the resemblance of the leaves.] 



Calyx 5-parted. Corolla with the limb personate, the upper lip bifid 

 with the lobes folded back — the lower lip trifid, closing the throat by 

 its prominent palate ; tube inflated, spurred at base. Stamens 4, didyn- 

 amous, — usually with a minute abortive rudiment of a fifth. Capsule 

 ovoid or globose, membranaceous, 2-celled, opening below the summit 

 by 1 - 2 pores or chinks, toothed. Seeds numerous, margined. Mostly 

 herbs, annual or pereaaial. Leaves alternate, rarely opposite or verti-

 terete, leafy, sometimes branched at summit and bearing 

 several racemes, generally growing in bunches or small 

 patches. Leaves 1-2 inches long, narrow, irregularly scaf- 

 tered on the stem, but very numerous. Flowers peduncu- 

 late, in a dense bracteate raceme — the peduncles shorter 

 than the bracts. Corolla pale greenish-yellow, smooth, —

Obs. This is extensively naturalized, — and 

 has become a vile nuisance in our pastures and 

 upland meadows. Mr. Watson, in his annaLs 

 of Philadelphia, says it was introduced from 

 Wales, as a garden flower, by a Mr. Eaxstead, 

 a Welsh resident of that city ; and hence one 

 of its common names. It inclines to form large patches, by means of 

 its creeping roots, — and as far as it extends, takes almost exclusive pos-
