Cult. This is a genus of delicate little shrubs and herbs. 

 Their culture and propagation is the same as for Smainsbnia. 

 The seeds of the annual kinds should be sown in pots early in 

 the spring, and placed in the greenhouse, where the plants will 

 soon rise, and when they have grown 2 inches high, they should 

 be planted separately in small pots, and shifted into larger ones 

 as they grow.

 land, one of the first superintendants of the Royal Botanical 

 Garden at Edinburgh, and author of a catalogue of the plants 

 grown in that garden in his time). R. Br. hort. kew. ed. 2.

 D. C. prod. 2. p. 273.) leaflets oblong-linear, and are, as well as 

 the branches and calyxes, pubescent; peduncles 2-3-flowered. 

 Tj . G. Flowers purple or scarlet. 



Small-leaved Sutherlandia. Shrub 2 to 3 feet. 



Cult. The species of Sutherlandia are very shewy when in 

 flower, being profusely clothed with large scarlet pea blossoms. 

 A mixture of loam and peat is the best soil for them, and they 

 may be propagated by young cuttings in sand under a bell- 

 glass, but the easiest and best method is by seeds, which ripen 

 plentifully in the gardens. The S. fruldscens will stand the 



winter if planted in a sheltered situation, protected by a mat 

 in severe weather.
