of yellow flowers. In habit it is quite distinct from the 

 common Scotch laburnum. The flowers growing on short 

 erect racemes and not in long drooping ones. It is a native 

 of the Dalmatian mountains, where it is said to be a bush. 

 The poisonous qualities of the laburnum appear to be more 

 concentrated in the present species. The Baron Welden, 

 " after whom it is named, assures us that its very flowers 

 produce head -ache. It forms an ornamental and pretty bush 

 and is easily grown. {Bat. Reg., Aug.)

TROP.EOLUM 



polypliylliim Many leaved Indian cress. An horbaceons plant ; growing 6 feet high ; 

 with yellow flowers ; appearing in summer ; a native of Peru ; increased by cuttings ; grown 

 in any good soil. Pax. Mag of Bot. Vol. X. p. 175. 



All the tropaiolums are ornamental plants. The well 

 known annuals, T. majus and its variety atrosanguineum, 

 are well known, as also the beautiful climber T. percgrinum. 

 The present subject is an upright growing species, without 

 any tendency to twine, and throws up strong shoots. The 

 leaves are scattered and very abundant ; leaflets, four to ten, 

 oblong or obovate, connected at the base, glaucous. The 

 petals are larger than the calyx, and of a beautiful deep 

 yellow; with along spur to the calyx, flowers axillary. 

 It blossomed for the first time in England, in 1839, in the 

 collection of Mr. Knight, of the King's Road. The root is 

 tuberous, and should be placed entirely below the earth. 

 Its treatment thus far has not shown it to be a free flow- 

 ering species ; yet much must be allowed for want of a 

 knowledge of its habit. It needs no other training 

 than to be tied to an erect stake. (Pax. Mag. Bat.,

A showy plant of the Bromeliaceous tribe, producing 

 large and compact spikes of scarlet and blue flowers. The 

 leaves are large, broad, and recurved, the main spike of 

 flowers issuing from the centre. It appears to be easy of 

 cultivation, and seems to bloom with freedom. It grows 

 well in light, rich, sandy soil, composed of open loam and 

 leaf mould in about equal proportions. It is a native of 

 Cayenne, in South America, and was introduced into the
