EVERLASTING FLOWERS, II 271 
fully arranged with other species from allied genera, have been much 
used for winter decoration. For this purpose the flowers are gathered 
as soon as fully expanded, and dried in a shady place, when they keep 
their form and colour. 
HELIPTERUM HUMBOLDTIANUM (Humboldt’s). Stems 
‘1 to 2 feet high; whole plant white and woolly at first, 
afterwards smooth. Leaves slender. Flower-heads small, in dense 
corymbs ; the petal-like bracts at first yellow, becoming green in drying ; 
July and August. 
H. Manewesit (Mangles’). Stems erect, branched, smooth, 12 to 
18 inches. Leaves broad-lance-shaped, eared at base, clasping the stem. 
Flower-heads large and showy, on long stalks; coloured bracts, pink, 
rosy, or deep purple at the base, florets yellow or purple ; July and August. 
The var. alba has white bracts and yellow florets. .The type and var. 
are shown in Plate 135. Commonly known as Rhodanthe Manglesii. 
The above species are annuals, and to grow them the 
seeds should be sown at the end of March or beginning of 
April, on rich soil in a warm sunny position out of doors. H. Manglesii 
is grown in large quantities as a pot-plant for the London market. For 
this purpose the seeds are sown in March, in five-inch pots, in light sandy 
soil and placed in a close frame or in a warm greenhouse; the young 
plants when large enough to handle are thinned out, about ten seedlings 
being left in each pot. They require careful watering and plenty of 
sunshine always. When in flower they may be placed in the open air. 
This plant also thrives when sown in a border in light sandy soil in a 
sunny position. 
Description of Helipterum Manglesii, the Rosy Everlasting Flower, 
_ -Flate185. is shown of the natural size. The fully-expanded head to 
the left of the Plate with the dark ring round the disk is the var. 
maculata. The white heads are those of the var. alba. Fig. 1 is a 
single floret enlarged, and Fig. 2 is the fruit enlarged and natural size,

Natural Order Composit. Genus Acroclinium 
AcROCLINIUM (from the Greek, akros, lofty, and ‘line, a bed). A small 
genus of herbs of similar appearance to Helipterwm, but differing 
chiefly in the character of the pappus-hairs. As we have seen, these 
are feathery in the case of Helipterwm, and in Acroclinium they may
