E. sysiiiloides appears to vary very much in the size and shape of its leaves and 

 size and angulation of its seeds. Probably when better known the above varieties 

 will be found to grade into each other by a series of intermediate forms so that they 

 can scarcely be distinguished from the type by the characters given. The manner in 

 which the involucres are peduncled in xar. pedunculata seems constant, but I have also 

 seen them with equally long peduncles mingled with the ordinary sessile condition on 

 the type. The type specimen of E. Holstii (Hoist, 530) and that of E. Volkensii 

 (Volkens, 638) are identical, and have shorter and more lanceolate leaves than in the 

 typical E. systyloidesy but do not otherwise differ, and as there are intermediate 

 forms, 1 do not consider it worth distinguishing as a variety. 



44. E. pseudoholstii, Pclc In Enyl. Jahrh. xxxiii. 287. Annual, 

 with the habit and general appearance of E. systi/loldes, Pax. Leaves 

 opposite at the flowering nodes, alternate elsewhere, subsessile, li-4 in. 

 long, 1-4 lin. broad, linear or linear-lanceolate, acute, tapering to the 

 base, entire or very minutely toothed, with a subulate spreading gland- 

 tipped tooth on each side at the base, glabrous on both sides. Stipules 

 none or exceedingly minute. Involucres generally '2-6 together in small 

 cymules at the tips of the branches, subsessile, | lin. in diam., cup- 

 shaped, very minutely puberulous, with 4 glands and 4-5 subquadrate 

 fringed lobes ; glands \-\ lin. in their greater diam., transverse, oblong 

 or subelliptic. Capsule exserted and curved to one side, about 2 lin. 

 long and IJ lin. in diam., oblong, minutely puberulous with curved 

 adpressed haii-s; styles J lin. long, erect, united at the basal part, bifid 

 at the apex, with the lobes parallel. Seeds Ij lin. long, dorsally 

 flattened, oblong, notched at the base and with a cap-like terminal 

 caruncle, slightly keeled down the back and with 3 grooves down the 

 inner face, whitish,

This is distinguished from E. sj/stgia, Edgew., and E. systyloides. Pax, which are 

 similar in general appearance, by the subsessile leaves, with a subulate tooth on each 

 side at their base and by the much snn\ller, more clustered involucres and different seed*.
