salina the branches are frequently so much developed as to 

 greatly exceed in length the primary stem, which is thereby 

 weighed down and rendered distinguishable by careful observa- 

 tion alone. From inhabiting the sea-shore it has usually been 

 called P. maritimum, but seems to differ materially from the 

 plant of Dillenius to which that name was intended to apply. 

 The receptacle is scarcely twice as long as broad, but is not con- 

 stant in shape. Segments of the leaves furrowed beneath and 

 opposite or alternate. Rachis of the leaves with a broad furrow 

 enclosing a keel beneath. 



Smithes P. maritimum is placed under this variety on account 

 of his description and the figure in ' Knglish Botany' agreeing far 

 better with it than with the M. maritima. He intended to include 

 the Dillenian plant, but appears to have been scarcely, if at all, 

 acquainted with it. In Hooker's 'Journal of Botany' (/. c.) the 

 accurate Mr. W. Wilson remarks, " Stem certainly not hollow. 

 Segments of the leaves not wholly destitute of points. Seeds 

 [fruits] of the hgulate florets with a deeply 4-lobed cup-shaped 

 crown, below which, externally, are two yellow oblong bodies 

 extending halfway down the seed, which is not in that part fur- 

 rowed, though it is deeply so on the other side. Segments of 

 the tubular florets keeled at the back, the line very prominent 

 just below the apex of the segment. I consider it a mere variety 

 commonly found on the sea-shore." An authentic specimen 

 from him is the M. inodora /3. salina. 



M. inodora grows on cultivated land and waste ground. /8. is 

 found by the sea. 



2. M. maritima (Linn.) ; stem diffuse, leaves pinnate, leaflets and 

 segments opposite fleshy Unear bluntish short, basal leaflets few 

 small separated from the others, heads solitary, phyllaries oblong 

 blunt with a scarious (pale) entire margin, fruit with two elongated 

 glandular spots just below the elevated lobed border.

Stems much more branched near to the base, often prostrate, 

 much shorter than those of M. inodora. Rachis of the leaves 

 only slightly enlarged at the base, and furnished there with very 

 few and short leaflets ; these are followed by a long naked space, 

 after which the rest of the leaflets are placed at pretty regular 

 intervals and are nearly equal in size. The involucre appears to 

 be flat. Phyllaries with their scarious border pale or narrowly 

 fringed with pale purple. Radiant florets oblong, shorter in
