A. Basedowii n. sp. 



Probabiliter frutex divaricatus, spinosus, ramulis gracilibus, 

 i:eretibus in spinam terminantibus. Phyllodiis augusto-spathu- 

 latis, obtusis, glandula minuta proxime infra mucronem brevem, 

 pilis brevibus albis tectis, ca. 1 cm, longis, 2 mm. maxima lati- 

 tudine, obscure 3-nerviis. Stipulis aristatis, pluribus basi phyllo- 

 diorum. Pedunculis solitariis vel geminis, 1 cm. longis, capitulis 

 globosis ca. 30 floris. Calyce obtuse lobato, lobis pilis albis 

 dense fimbriatis, corolla? minus dimidium sequante. Petalis sparse 

 villosis. Ovario glabro. Legumen ac semen non vidimus. 



Evidently a divaricate thorny shrub, but no particulars 

 available as to size, etc. The few specimens available 

 show slender terete branches, white with a pellicle and 

 sparingly besprinkled with short white hairs, terminating 

 in spines. 



Phyllodia narrow-spathulate, obtuse, with a minute gland 

 immediately beneath the short mucro. Closely besprinkled 

 with short white hairs. Not much more than 1 cm, long 

 and about 2 mm. in the widest part, obscurely 3-nerved, 

 with intermediate secondary nerves. Stipules aristate, 

 several at the base of each phyllode. 



Peduncles singly or in pairs, about 1 cm. long, each 

 bearing a globular head of about 30 flowers, 5-merous, the 

 buds closely packed. 



Calyx obtusely lobed, the lobes densely fringed with 

 white hairs, less than half as long as the corolla. Petals 

 sparingly besprinkled with hairs. Ovary glabrous. Pods 

 and seed not seen.
