Scroph^{,larine<z D^plac^ls. 347 



16. DlPLACUS. 



This genus is very near the last, but most of the species 

 are woody at the base. The main distinction, however, is in 

 the seed-vessel, which opens in valves with the seed-bearing 

 placentas attached to them. The name is from &'$, double, 

 and TrXaKvos, a placenta, referring to the separation of the 

 placenta into two parts. 



1. D. glutindsus, syn. Mimulus glutinosus. A robust 

 growing perennial from 2 to 3 feet high, with funnel-shaped 

 almost regular flowers, orange-coloured in the original variety. 

 But since its introduction, about a century since, it has given 

 birth to several marked varieties which have been described as 

 distinct species. They may be reduced to four principal forms : 

 D. aurantlacus, orange-coloured flowers, having the lobes of 

 the corolla emarginate ; D. puniceus, cinnabar flowers with 

 emarginate lobes ; D. latifolius, yellow flowers, larger broader 

 leaves, and rounded corolla-lobes ; and D. grandiflorus, re- 

 markable for the unusual development of the limb of the corolla, 

 and its deeply bilobate divisions. The colour here is rather 

 variable, ranging in every shade from pure white to nankeen 

 yellow, uniform, or covered with spots. This species is from 

 California, and somewhat tender. 



Sibthorpia Europcea is an interesting slender creeping herb 

 with minute reniform hairy leaves and solitary axillary flowers. 

 It is found here and there in the South and West of England 

 and Ireland. This rapidly covers the ground in damp shady 

 places. 



17. BUDDLBA. 



A large genus of shrubs, herbs, or even small trees. Leaves 

 opposite, commonly densely tomentose, especially on the 

 under surface. Flowers small, often tomentose, axillary, spicate, 

 capitate, or thyrsoid. Calyx equally 4-toothed. Corolla 

 tubular-campanulate, regular ; limb spreading, 4-toothed. 

 Stamens 4, included. Capsule dehiscing septicidally in two 

 valves. About eighty species are known, inhabiting America, 

 Africa, and tropical Asia. The genus was named after Buddie, 

 an English botanist. This and some of the allied genera are 

 now usually referred to Loganiacece, but having overlooked this 

 genus there we introduce it in its old place. 



1. B. globosa. This is a shrubby species, and the only one 

 at all common in British gardens. Leaves linear-lanceolate.
