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

 373., that the involucrura is ovate-oblong both when in flower and in seed, not 

 becoming ventricose as in C. virens. S .

Foliis quaternis revoluto-linearibus ciliatis suprk tomentosis, floribus capi-

Stems branched only towards their base. Leaves and sepals linear-lanceolate, 

 downy, their margins recurved so as almost to meet behind, ij . 



8. E. Mackaiana. 



Foliis quaternis ovatis ciliatis supra glabris, floribus capitatis pedicellatis, 

 sepalis ovatis ciliatis glabris, pedicellis pilosis et tomentosis, corolla ob- 

 longo-ovata, antheris 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 dificrence in 

 habit. It agrees with E. ciliaris in the character of its foliage, but differs
