Var. 8, tomentosa (N. E. Br.); leaves more or less tomentose or very densely 
pubescent beneath with longer hairs than in the type ; outer corona-lobes subulate 
or filiform, rather long and the pairs of teeth alternating with them usually well 
developed.

corona-lobes filiform, very (2 lin.) long, with the alternating pairs of teeth nearly 
or quite obsolete ; otherwise as in the type. 
' Var. 5, obsoleta (N. E. Br.) ; leaves narrowly deltoid-lanceolate to ovate, acute, 
cordate with a broad shallow open sinus at the base, thinly and minutely 
puberulous above, nearly or quite glabrous beneath ; outer corona-lobes narrowly 
deltoid-subulate, minutely notched at the apex, channelled down the face, without

The corona of this plant either varies considerably or more than one species is 
here included, but from dried material I am unable to discriminate more than the 
forms indicated. Dr. Bolus’ specimens 10195, 10196, 10197, have a rather more 
inflated corolla, which dries of a more reddish tint than usual, but otherwise seem 
the same as the other specimens quoted. The genus requires to be studied from 
living specimens. Asclepias peltigera, Schlechter, has also been distributed by 
Cooper as no, 2719.
