cells from which they have developed, have far thicker and 

 more highly porose lateral walls than the surrounding cells; 

 the finely-drawn circle which surrounds the thickly-drawn 

 glandular-head, indicates the place of contact between the 

 basal cell of the hair, and the outer wall of the epidermal 

 cell; the smaller circle at the top of the head indicates that 

 the cuticle at this place is lacking, thus forming a pore 

 only spanned by the cellulose wall, as described by Percy 

 Groom for P. palustris.

Sympodial hemicryptophyte of semi or entirely rosette 

 type, the above-ground part of the shoot bearing the in- 

 florescence being either furnished with a few foliage-leaves, 

 or being totally devoid of them. 



The species may form tufts, (a specimen from Herschell 

 Island belonging to formå lanata Walpers, had numerous 

 rosettes of foliage-leaves, even seven flowering shoots and 

 10 withered peduncles from previous years) and in this case 

 it has a short mesocorme ("rhizoma multiceps"), a fairly 

 thick primary root, sometimes probably of long duration, 

 adventitious roots being only few in number, but rather 

 vigorous; more frequently it appears, however, that the 

 basal portion of the main shoot dies away, perhaps even
