THE DICTIONARY OF GARDENING, 



Actinomeris continued. 

 A. sqnarrosa (rough-headed).* fl. -headt yellow, in loose terminal 



panicles. July and August. I. decurrent, broadly lanceolate, 



coarsely toothed. Stem square, winged, h. 3ft. North America, 



1640. SYN. Verbesina Careopsit. 

 ACTINOPHYLLUM. See Sciadophyllum. 

 ACTINOSTACHYS. Included under Scliizaa 

 (which see). 



ACTINOTUS (from actinotos, furnished with rays ; re- 

 ferring to the involucre). OBD. Umbelliferce. An Austra- 

 lian genus of greenhouse herbaceous perennials. Flowers 

 shortly pedicellate, numerously disposed in simple umbels ; 

 petals none. Leaves alternate, petiolate. They thrive best 

 in loam and peat, and are increased by root division and 

 seeds. The latter should be sown on a hotbed, in spring, and 

 in May the seedlings may be transplanted out in the open 

 border in a warm situation, where they will flower and 

 seed freely. 

 A. helianthus (sunflower).* fl. white, in many-flowered capitate 



umbels; involucre many leaved, radiating, longer than the 



flowers. June. 1. alternate, bipinnatifld ; lobules bluntish. 



h. 2ft. 1821. SYN. Eriocalia major. 

 A. leucocophalus (white-headed), fl. white. June. h. 2ft 1837.

ACULEATUS. Armed with prickles. 



ACULEOLATUS. Armed with small prickles. 



ACULEUS. A prickle ; a conical elevation of the skin 

 of a plant, becoming hard and sharp-pointed.

ACYNTHA. A synonym of Sanseviera (which see). 

 ADA (a complimentary name). OBD. Orchidece. An 

 evergreen orchid, very closely allied to Brassia, from 

 which it differs chiefly in having the lip parallel with, 

 and solidly united to, the base of the column. Some 

 authorities now refer the plant to the genus Mesospi- 

 nidium. It requires to be potted in peat and sphagnum, 

 in equal parts. The drainage must be perfect, and, during 

 summer, the water supply profuse. Although in winter 

 far less will suffice, the plant should not be allowed to 

 become dry. Propagated by divisions as soon as the 

 plant commences growth. 



A. aurantlaca (oi-ange).* fl. orange-scarlet, in long terminal 

 nodding racemes, each bearing from six to ten blossoms ; petals 

 elongated, streaked with black inside. Winter and spring. /. two 

 or three to each plant, linear, dark green, about 6m. in length. 

 Habit erect, with somewhat cylindrical pseudo-bulbs, which 

 taper upwards. See Fig. 25. 



AD AMI A (named after John Adam, some time Governor- 

 General of India, and a promoter of natural history). OBD. 

 SaxifragecB. A small genus of Hydrangea-like greenhouse 

 evergreen shrubs, having many flowered terminal corymbs of 

 flowers, and opposite, petiolate, oblong-lanceolate, serrated 

 leaves. They thrive well in a mixture of loam, peat, and 

 sand ; and cuttings will root readily in a similar compost, 

 under a hand glass.

 ADANSONIA (named after Michael Adanson, an 

 eminent French botanist). OBD. Sterculiacece. This is 

 reputed to be one of the largest trees in the world, as far 

 as the girth of the trunk is concerned ; but it is seldom 

 seen in cultivation in this country. 

 A. digitate (finger-leaved). Baobab-tree ; Sour Gourd, /.white, 



about 6m. across, with purplish anthers, on long, axillary, solit 



pedicels. I. palmate, with three leaflets in the you 



five to seven in adult ones. h. 40ft. Africa.

 male ; the anthers terminate in a globose gland). OBD. 

 Rutacece. Very beautiful little greenhouse shrubs from 

 the Cape of Good Hope. Flowers large, usually solitary 

 at the tops of the branches ; stamens ten, the five opposite 

 the petals sterile, five fertile ones similar in form, but 

 shorter. Leaves usually alternate, flat, glandularly dotted. 

 They thrive in a mixture of sand and peat, with a little 

 turfy loam. The young tops, before they begin to throw 

 out their buds, made into cuttings, and planted in a pot 

 of sand, with a bell glass placed over them, will root 

 without bottom heat. 



A. acumlnata (acuminate). Synonymous with A. amcena.
