of our Botanic Gardens, are natives of Australia, some 

 growing to a height of 20 feet; the foliage is strikingly 

 handsome, usually serrated, dark-green above, covered with 

 silvery hairs on the under surface ; the inflorescence takes 

 some considerable time to develope. The plant exhibited 

 has now beeii in ilower for more than two months. 



WhitfichU" latcritia is an acanthaceous shrub, named 

 after Mr. T. Whitfield, a botanical collector, and is a native 

 of tropical Africa. The genus consists of only two species 

 the one under notice being the only one as yet introduced 

 to cultivation. Its terminal racemes of flowers are pro- 

 duced in October, continuing to bloom till late in the 

 spring months. 



Conjnosfi/lis Hyhantlms, Mart. — This pretty stove 

 climbing shrub is remarkable as being a member of the 

 order Vwla.ria; and was introduced from Para in 18*70. 

 The flowers are produced freely, in racemes ; the lower 

 petal of the flower, which is the largest, forms a long- 

 spur, somewhat like that of a large white violet. A fine 

 figure of the plant will be found in the " Botanical 

 Magazine," 5960. It is rarely met with under cultiva- 

 tion. Sir J. Hooker describes it as a very variable species, 

 being of the opinion that all the so-called species of the 

 genus hitherto described are referable to one. 



Mancttia hicolor. — Producing its bright scarlet and 

 yellow flowers in abundance from the axils of the light 

 green leaves, this plant is well worthy of a place in our 

 collections. Messrs. Veitch are credited with the intro- 

 duction of this species in 1843, from the Organ Mountains. 

 Treated as a climbing plant, in a warm greenhouse, it 

 exhibits its true character to perfection. Belonging to 

 the order Rv.hmcccr, it is closely allied to Bouvardia. 



In addition to these, there are on the table : Ccntro- 

 pogon Lncyanvs, Hort., — a hybrid between the Mexican 

 C. fastuosus, Scheidw., and the Brazilian Siphocav^jijlus 

 hetida'folins, Don., raised by M. Despond at Marseilles, 

 1856. Crassida ladca, Soland, — a Cape plant. Wallirhia 

 densiflora, Mart., — from East Indies. Plumhago rosea, 

 Linn., — an Indian plant. Cuscuta reflcxa, Roxb.,- — from 

 India ; and the beautiful winter-flowering East Indian 

 fyomcea Horsfidli(i\ Hook, var. Ehccdii, and var. Bru/g.m.
