PIMELEA (from pimele, fat; alluding to the oily 

 seeds). Rice Flower. SYNS. Banksia (of Forster), 

 Cookia. OBD. Thymelceacece. A large genus (seventy- 

 six species have been described) of beautiful, greenhouse 

 trees, shrubs, or rarely herbs, natives of Australia and 

 New Zealand. Flowers hermaphrodite or rarely dioecious, 

 capitate-spicate or fascicled, terminal or axillary, very 

 rarely solitary ; perianth with a cylindrical tube, and 

 four spreading or rarely erect lobes ; stamens two, 

 affixed to the throat. Leaves opposite or scattered, 

 usually rather small. Most of the species which have 

 been introduced are described below ; except where 

 otherwise stated, they are shrubs, and inhabitants of 

 Australia. 



Pimeleas are compact, free-growing, and very desirable 

 greenhouse plants, especially as they flower when most 

 of the other hard - wooded representatives are past. 

 Their flower-heads are borne in the greatest profusion 

 on the points of shoots that are made annually, those 

 of one season flowering in that next following. The 

 plants succeed in good fibrous peat and silver sand, or 

 they may be grown as stronger specimens with loam 

 instead of peat, if it is of good quality, and contains 

 plenty of fibre. Cuttings, made of the young shoots, 

 when they are about 2in. long, will root, if inserted, in 

 spring, in a compost of one part peat to two of silver 

 sand, and covered with a bell glass. They should be 

 placed in an intermediate house, kept moist, and shaded 

 from sunshine. When roots are formed, gradually 

 admit air, and, in due course, pot off singly, and 

 grow the plants on in a close, moist atmosphere until 

 established, when a more airy situation will be 

 best. Established flowering plants of Pimeleas may 

 be treated somewhat like others of a hard-wooded de- 

 scription, except that they require rather more water 

 and syringing. They are more than usually susceptible 

 to the attacks of Bed Spider, and, if this is allowed a 

 footing, much injury will ensue. Pimelias may also be 

 raised from imported seeds, when these are obtainable ; 

 young plants flower when they are very small, if allowed, 

 but this is not advisable, as it tends to unduly weaken 

 them. The habit assumed is such as to require but 

 little training beyond stopping shoots on young plants 

 that are inclined to take a lead. Each year, after flower- 

 ing, all the heads should be cut over, and any necessary 

 repotting attended to so soon as the new growth has 

 commenced. The most beautiful species is P. spectabilis ; 

 others specially noteworthy are P. ferruginea, and P. ligus- 

 trina hypericina. The first-named and the last will grow 

 into large specimens if desired; P. ferruyinea is of a 

 much more dwarf and compact habit.
