34. A. argentea (Linn. Spec. p. 1002? non herb.) foliis ternis 
fasciculatisve parvis obovatis oblongisve sericeis glabratisve, callo 
sub foliis aculeato, capitulis depresso-globosis paucifloris, foliis 
involucrantibus obovato-orbiculatis calyce multo brevioribus, 
. calycis villosissimi laciniis lanceolatis tubo brevioribus, carina alis 
paullo breviore, ovario 5—8-ovulato.—4A. argentea a. E. Mey. ! 
Comm. p. 43.—4A. stawrantha, Eckl. Zeyh. Enum. p. 202.— 
Frutex divaricato-ramosissimus, ramulis tenuibus rigidis sub- 
recurvis. Species precedenti (cum qua junxit E. Meyer) affinis, 
sed distincta videtur foliis magis sericeis et raro elongatis, capitulis 
minoribus sepe 2—3-floris, villis florum magis sericeis et bracteis 
multo brevioribus fere orbiculatis. 
Sandy hills of Cape district, Drège! Sands of the mouth 
of the Boschmanns river, Zeyher! n. 422, also Burchell’s n. 7455 ! 
and in several other collections. Many species of this series 
have received by various authors the name of argentea ; but 
E. Meyer is probably correct in considering this as the true one, 
although it is not in Linneus’s herbarium, where the name of 
argentea is given to the A. sericea, A. virgata, A. heterophylla 
and A. æmula, and although Linneus’s expressions “floribus 
sparsis" in his diagnosis, and * capitula hirsuta" in the descrip- 
tion are somewhat contradictory. 
B. mutica; calo sub folis mutico, capitulis laxioribus nume- 
rosis fastigiato-paniculatis. Ramuli breves rigidi.

35. A. ferruginea (Herb. Banks ! MS.), ramulis rigidis 
Subspinescentibus, foliis fasciculatis ternisve oblongo- v. cuneato- 
linearibus acutiusculis sericeo-pubescentibus, callis aculeatis, 
floribus 1-3-nis, calycis villosi subinflati dentibus triangularibus 
tubo multo brevioribus, ovario 4-5-ovulato, legumine oblique 
ovato-lanceolato.—A. tridentata, Eckl. Zeyh. Enum. p. 201; ; 
E. Mey. Comm. p. 43 et Auct. plur. vix Linn.—Frutex humilis, 
rigide ramosissimus, tomento sericeo fulvens v. canescens. Folia 
maxima 5-6 lin. longa, sed pleraque multo minora. Flores intra 
fasciculos superiores sessiles, solitarii v. per 2-3 glomerati, 
. sed nunquam revera in capitula terminalia dispositi. Calyx
