256 Composite Rhodan the. 



28. EHODANTHE (Acroclinium). 



Elegant little annuals with everlasting flower-heads. In- 

 volucral scales scarious, outer ones sessile, inner clawed, coloured 

 and petaloid. Keceptacle naked ; florets all tubular and simi- 

 lar. Achenes villous, not beaked ; pappus feathery, in a single 

 row. The two or three species here included are Australian. 

 Name from pcSov, a rose, and avQos, a flower, in allusion to the 

 colour of the flower-heads. 



It is worthy of remark that here, as in most other < Ever- 

 lasting Flowers ' belonging to this order, the coloured conspicu- 

 ous and lasting part is the involucre. 



1. R. Manglesii. From a foot to 18 inches high, with smooth 

 glaucous oblong entire perfoliate leaves and a branching inflor- 

 escence. Outer bracts silvery. Flower-heads pedunculate, 

 delicate rose-pink with a yellow centre. The variety maculata 

 has a dark band around the disk ; and alba has all the bracts 

 of a silvery white. R. atrosanguinea has purple florets and 

 is otherwise very distinct. 



2. R. rosea, syn. Acroclinium roseum. This species is 

 perhaps even handsomer than the preceding. It is a more 

 erect plant, from 1 to 2 feet high, having linear acute leaves 

 and larger solitary terminal flower-heads. Outer bracts brown, 

 inner pink or white ; florets yellow. 



29. WllTZIA (Morna). 



Annuals of less graceful habit than those in the last genus, 

 but almost identical in floral characters, the main difference 

 being in the achenes, which terminate in a slender beak 

 bearing the pappus. Involucral bracts all coloured, gradually 

 passing from small sessile outer ones to those with a slender 

 claw and large limb. There are about six species,, all from 

 Australia. This genus was named in honour of a German 

 botanist. 



1. W. corymbosa, syn. W. acuminata. An erect and 

 branching plant clothed with a rough pubescence. Leaves 

 linear, with revolute margins clasping the stem. Flower-heads 

 yellow or pink, in dense terminal corymbs. Involucral bracts 

 with long acuminate points, usually with a few straggling 

 ones below the head. Terminal beak much longer than the 

 achene.
