5-toothed. P. pulechella, in which the calyx has two 
entire or emarginate lips, cannot be referred to the last 
section. If it must be placed in one or other of the 
remaining sections it is to Huprostanthera rather than to 
Klanderia that it should be referred, but it does not by any 
means satisfactorily accord with the characters exhibited 
by the other species of the section. In the gardens of 
Tresco Abbey P. pulchella forms a shrub which thrives 
well in the open and flowers freely in April. At Kew it 
is cultivated in the Temperate House, where it grows 
satisfactorily when planted in sandy peat and given the 
treatment suitable for species of Boronia and other Austra- 
lian genera. 
Descriprion.— Undershrub; about 14 ft. high, of graceful 
habit and freely flowering ; twigs spreading, sparingly 
finely adpressed puberulous. Leaves subsessile, linear or 
linear-lanceolate, 13 in. long, 1 lin. wide, obtuse or rounded, 
entire, almost glabrous, sparingly gland-dotted. Mowers in 
lax erect rather strict 10—18-flowered racemes, 2-3 in. long ; 
bracts like the leaves but smaller, as long as or rather 
longer than the 1-2 lin. long pedicels which are adpressed 
grey-puberulous and 2-bracteolate at the tip. Calyc about 
24 lin. long, sparingly finely puberulous and glandular out- 
side, densely puberulous near the top within, lips entire or 
emarginate, the upper rather shorter than the lower, remain- 
ing open after flowering. Corolla subrotate, faintly 2-lipped, 
lilac, the tube white at the base, the throat with dark purple 
dots; tube about 2 lin. long, narrow at the base; limb 
8 lin. wide; upper lip 2-lobed, slightly arched, 24-3 lin. 
long, 43 lin. wide, lobes obovate, 2 lin. long and about as 
wide, faintly imbricate and crenulate ; lower lip spreading, 
3 lin. long, lobes oblong or elliptic, 25 lin. long, about 2 lin. 
wide, crenulate. Stamens didynamous, the larger pair 
barely reaching the middle of the corolla; anthers puberu- 
lous and without appendages. Nutlets obovoid, glabrous, 
foveolate.
