318 Ewart and White: 



young, are more or less covered with white hairs. The leaves 

 are \-\ an inch long, with short petioles and densely covered 

 on both surfaces with soft, woolly, white hairs, linear-lanceolate, 

 flat, slightly pointed, alternate, a few opposite. Flower heads 

 compound on short axillary branches springing from the main 

 branches or from the secondary ones. The diameter of each 

 compound head almost spherical, 3-4 millimetres diameter, but 

 possibly larger when fully ripe. The peduncles and outer bracts 

 of the involucre are densely covered with white hairs. There 

 are only a few bracts in the general involucre ; 2 or 3 of the 

 outermost are almost leaf-like, have a filiform scarious tip, and 

 are covered on both sides with long, soft white hairs. The other 

 bracts of the general involucre have a leaf-like centre Vith 

 scarious margins, a bunch of hairs each side, and conspicuous, 

 scarious, not radiating tips. The receptacle is apparently 

 branched. There are 3-4 partial heads in each compound head, 

 and each is very distinct and very slightly flattened, be'ng 

 almost round in outline. Tbere are 20-30 bracts round each 

 partial head, all of which have radiating tips and are exactly 

 similar to the inner bracts of the general involucre. The more 

 central bracts of the partial heads have thin scarious tips in- 

 curving over the top of each partial head. Inside the innermost 

 bract is a small cavity in which are situated 3-8 florets, wilh a 

 quantity of upright soft, white woolly hairs between them. 

 Each flower appears to be hermaphrodite, but the achene is 

 very deciduous in the dried specimens. The achene is very 

 small, obtuse at the tip, and is slightly hairy. The pappus con- 

 sists of a varying number of long, plumose, soft, woolly white 

 strands, which may or may not be very slightly united at the 

 base to form an imperfect ring. The corolla is pale yellow, 

 and 5-tootlied ; the floret is thickened at the base. The anthers 

 are united, and have short, fine tails. The style is divided 

 into two branches, which are spreading and are not thickened 

 at their bases.

A specimen from the Plantae Preissianae of Lehmann (vol. i., 

 p. 490, No. 71) is allied in some respects to this species, but 

 being without fully developed flowers, cannot be exactly placed.
