I need only add to Sir J. E. Smith's excellent description, in Engl. FT. iii.

Stems branched only towards their base. Leaves and sepals linear-lanceolate, 
downy, their margins recurved so as almost to meet behind. p.

Foliis quaternis ovatis ciliatis suprà glabris, floribus capitatis pedicellatis, 
sepalis ovatis ciliatis glabris, pedicellis pilosis et tomentosis, corollà ob- 
longo-ovata, autheris aristatis inclusis, stylo exserto. 
Stem erect, about a foot high, leafy, downy, densely branched from top to 
bottom. Leaves spreading, 4 in a whorl, stalked, ovate, their margins 
slightly revolute, glabrous, ciliated, white beneath. Flowers capitate, 
erect or pendulous, of a rather dark rose colour, on downy stalks, upon 
which are also a number of long silvery hairs, generally glandular: sepals 
ovate, ciliated, glabrous; corolla oblong-ovate ; anthers inclosed, awned 
at their base; style exserted.

Distinguished from E. Tetralix by the form and structure of its leaves and 
sepals, the glabrous upper surface of the former, and its total difference in 
habit. It agrees with Æ. ciliaris in the character of its foliage, but differs
