PB ACTIO AL GUIDE TO GABDSN PLANTS amoepha 



blue, rosy or white in colour. Calyx lobes 

 nearly equal, the 2 upper ones often united. 

 Petals about as long as or shorter than the 

 keel ; standard ovate or round, contracted 

 into a claw, or furnished with small in- 

 flexed auricles ; wings oblong, somewhat 

 sickle-shaped ; keel blunt, incurved. Pod 

 ovate, indehisoent. 



P. glandulosa. — A rather pretty 

 Chilian shrub 2-4 ft. high, with ternate 

 leaves composed of ovate lance-shaped 

 tapering leaflets. The white flowers, 

 tinged with blue, are borne from May to 

 September in spiked racemes, issuing from 

 the axils of the upper leaves. 



Cultwre and Propagation. — This 

 species is rarely met with, but it is fairly 

 hardy at Kew in warm positions and 

 would no doubt be quite hardy in the 

 mildest parts of the south and west. It 

 will grow weU in ordinary good garden 

 soil, and may be increased by cuttings of 

 the plump shoots in early summer, placed 

 mider a handlight or in a cold frame or 

 greenhouse. 



There are several herbaceous species 

 to be met with chiefly in botanic gardens, 

 viz. bitumdnosa, from South Europe ; 

 macrostachya, from California; and 

 Onohrychis and physodes from the more 

 northern parts of Ainerica. 



AMORPHA (Bastard Indigo). — A 

 genus with 8 species of smooth or downy 

 shrubs or undershrubs. Leaves oddly 

 pinnate with numerous glandular-dotted 

 leaflets. Stipules small or none. Flowers 

 densely spioate, racemose, terminal. 

 Calyx lobes almost equal. Standard 

 ovate, erect, contracted into a claw ; 

 wings and keel absent. Stamens 10, 

 united. Pod short, long, sickle-shaped or 

 crescent-shaped. 



Culture and Propagation. — These 

 plants thrive in ordinary garden soil, but 

 reqviire shelter in bleak localities. They 

 may be increased by layers or cuttings, the 

 latter being taken off at a joint and in- 

 serted in a sheltered place in sandy soil in 

 autumn, allowing them to remain about 

 a year. They should be protected with 

 handUghts during the winter months. 

 Stickers, which are freely produced, may 

 also be used to increase the plants, 



A. canescens {Lead Plant). — A hoary- 

 looking plant 3 ft. high, native of Missouri. 

 Leaflets ovate-elliptic, sharply pointed. 

 Flowers in July, dark blue. 



Culture dc. as above. 



A. fruticosa. — A smooth or slightly 

 hairy species 6 ft. high, native of Carolina. 

 Leaflets eUiptic-oblong. Flowers in 

 June and July, very dark bluish-purple 

 or violet, with conspicuous yellow sta- 

 mens. In catalogues will be found 

 numerous so-called varieties of this 

 species, but it is very diflioult to dis- 

 tinguish one from another. Indeed in the 

 Kew Handlist of Trees and Shrubs as 

 many as 1.5 distinct synonyms are given 

 for this species. 



Culture dc. as above. 



PETALOSTEMON ' (Prairie 

 Clover). — A genus with 14 species of 

 usually perennial, glandular, dotted herbs 

 with oddly pinnate leaves. Stipules 

 minute, bristly. Flowers in heads or 

 terminal spikes, or opposite the leaves, 

 often stalked. Calyx lobes nearly equal. 

 Standard, with a free slender claw, heart- 

 shaped or oblong, concave or cup-like. 

 Stamens 5, united at the base. Pod, 

 including the calyx, membranous. 



Culture and Propagation. — The 

 following species are best known but are 

 not very much cultivated. They thrive 

 in sandy loam with a little peat or leaf 

 mould, and may be increased by dividing 

 the rootstocks in spring. 



P. candidus. — AN. American per- 

 ennial, 1 ft. high. Leaflets 7-9, lance- 

 shaped or linear oblong. Flowers in 

 July, white, in oblong or cylindrical 

 heads. 



Culture dc. as above. 



P. violaceus. — Also a N. American 

 perennial 1 ft. high, leaflets 5, narrow, 

 linear. Flowers in July, rosy-purple, in 

 globose, ovoid, or oblong - cylindrical 

 heads. 



Culture dc. as above. 



INDIGOFERA (Indigo).— A genus 

 with over 200 species of herbs or under- 

 shrubs. Leaves oddly or evenly pinnate, 

 rarely digitately 3-foliolate. Flowers in 

 axillary racemes or spikes. Calyx lobes 

 small, nearly equal. Standard ovate or 

 roundish ; wings oblong, slightly cohering 

 to the straight blunt or pointed keel. 

 Stamens 10, upper one free. Pod globose, 

 oblong or linear, straight, arched, or 

 rarely crosier -like. 



I. decora. — A pretty evergreen shrub 

 1-3 ft. high, native of China and Japan. 

 The pinnate leaves are composed of 2-6 

 pairs of bluntly ovate mucronate leaflets^
