Archangelica—continued. 
Northern Asia, and America. Flowers white or greenish, 
in compound, many-rayed umbels; involucral bracts small 
or wanting. Leaves pinnately decompound. Only one species 
calls for description here. For culture, &c., see Angelica. 
A. officinalis (officinal), Common Angelica. jl. greenish; 
involucel as long as the umbellets. uly. 7. bipinnately 
divided; segments sub-cordate, lobed, acutely serrated, the 
terminal one three-lobed. Europe (but not indigenous in 
Britain), Syn. Angelica Archangelica. 
ARCHONTOPHGNIX (from archonte, chief, and 
Phenia; in allusion to their majestic aspect and their 
relationship). Orp. Palme. A small genus (two species) 
of tall, stove, unarmed Palms, natives of Eastern 
Australia. Flowers rather large, monecious in the same 
spadix, spirally disposed; spadices shortly pedunculate, 
the branches and branchlets pendulous; spathes two, 
complete, caducous; inflorescence under the leaves. 
Leaves terminal, equally pinnatisect; segments linear- 
lanceolate, acuminate or bidentate at apex. Caudex 
marked with annular scars. The two species, A. Alez- 
andre and A. Cunninghamii (see Fig. 76), were formerly 
included under Ptychosperma (where they will be 
found described). 
ARCTIA. Orv. Lepidoptera. A genus of gaily- 
coloured Moths, two species of which are found in gardens. 
The larve are destructive to Lettuce, Forget-me-Nots, and 
other plants. Being hairy, the larve are seldom taken by 
insectivorous birds. The Cuckoo, however, will devour 
them greedily. See Tiger Moth. 
ARCTIO and ARCTIUM (of La Marck). Synonyms 
of Berardia (which see). 
ARCTOCALYX. Included under 
(which see). 
ARCTOSTAPHYLOS. Bentham and Hooker in- 
clude Comarostaphylis here, but it has been kept distinct 
on p. 364, Vol. I. The genus includes fifteen species, 
of which two inhabit the colder regions of the Northern 
Hemisphere, and the rest are Mexican and Californian. To 
the species described on p. 108, Vol. I., the following 
should be added:

clusters. Spring. fr. reddish, sub-acid. 7. obovate or oval, 
varying to lanceolate-spathulate, cuspidate-mucronate, thicker 
than in A. Uva-ursi, abruptly petiolate. Sierra Nevada, Cali- 
fornia, 1896. A prostrate, evergreen bush. 
ARCTOTIS. This genus comprises about thirty 
species: one is Abyssinian, and the remainder are South 
African. Leaves radical or alternate. To those described 
on p. 108, Vol. I., the following should be added. One 
or two species formerly included here are now referred 
to Cryptostemma. -

Icacorea. Of this genus there are about 200 species, 
broadly dispersed through tropical and _ sub-tropical 
regions, but very rare in tropical Africa. To those de-
