united. Germen nearly round, sub- 

 sessile, green ; style rather longer 

 and much stouter than the pedicel, 

 oblique, pubescent, flat in front, of 

 nearly the same colour as the pe- 

 rianth ; stigma oblique, flat, with a 

 projecting point in the centre, shin- 

 ing, gi-een. 

 The seeds were sent by Mr Fraser 

 from New Holland in 1824; the 

 plants were raised last year, and 

 have already flowered freely in 

 the greenhouse. The species be- 

 longs to Section B. Ptychocarpa 

 of Brown, Linn. Soc. Trans, vol. x. 

 p. 172. and so nearly agrees with 

 the description of G. arenaria, that 

 I should have hesitated in consi- 

 dering it distinct, had it not been 

 for the recollection of Mr Mac- 

 nab, the excellent Curator of the 

 Royal Botanic Garden, who as- 

 sured me that it was different from 

 the plant which he once knew at 

 Kew under that name, — an obser- 

 vation the truth of which has since 

 been confirmed by Dr Hooker, from 

 a comparison with a specimen of G. 

 arenaria in his possession. The 

 early period at which this shrub 

 flowers, after being raised from 

 seed, suggested the specific name 

 of prcBcox ; but Dr Hooker having 

 sent to the engraver, under the 

 name of G. pubescens, a drawing 

 kindly supplied by Dr Greville, I 

 have adopted this designation. 



Habenaria fimbriata. 



This very splendid species, along with 

 many other rare American plants, 

 I had the honour to receive from 

 the Countess of Dalhousie, before 

 her return to Canada last autumn ; 

 and magnificent specimens 2 feet 

 high, are now in flower in a cold 

 frame. 



Heliophila arabioides. 



Laurus Cassia. 



Lobelia crispa. 



Spec. Char — L. crispa; spica ter- 

 minali, foliosa, foliis crispis, den- 

 tato-serratis, sessilibus, superiori- 

 bus linearibus, acuminatis, inferi- 

 oribus lanceolato-spathulatis. 



Descript — Root fibrous (annual?). 

 Stem erect (5 feet high), generally 

 simple, angled, proper juice milky. 

 Leaves scattered, sessile, sub-am- 



plexicaul, veined, indistinctly pu- 

 bescent, deeply tooth-serrated, ser- 

 ratures occasionally toothed, upper 

 leaves linear, pointed, gradually di- 

 minishing to the extremity of the 

 spike, crisped ; lower leaves lan- 

 ceolato-spathulate, and less crisp- 

 ed. Spike very long. Flowers so- 

 litary, in the axils of the brac- 

 tese. Peduncles equal in length 

 to the germen. Calyos segments 

 pointed, nearly as long as the tube 

 of the coroUa, ciliated, serrated, at 

 first reflexed, afterwards spread- 

 ing at right angles, persisting, 

 and becoming larger. Corolla mar- 

 cescent, limb lilac, faux and tube 

 white, 2 upper segments small, 

 linear, pointed, reflexed, 3 lower 

 larger, obovate, acuminate, spread- 

 ing, the central lobe rather the 

 smallest ; tube bent down, straight, 

 nearly cylindrical, when beginning 

 to fade, cleft in its whole length 

 above, and from its base nearly to 

 the faux on each side. Filaments 

 flat, unconnected, hairy on their 

 outer surface, white, with a slight 

 tinge of purple on the outside. 

 Anthers connected throughout, deep 

 purple, hard. Pollen yellow. Ger- 

 men green, partly superior, obovate, 

 bilocular. Style compressed, thick- 

 ening upwards. Stigma oblique, 

 cleft transversely, pubescent round 

 its base, segments revolute. Seeds 

 very numerous, receptacle large, 

 and attached to the centre of the 

 dissepiments. 



Native of Mexico. Has been culti- 

 vated in the stove, but suffers from 



. great heat. Seeds were received 

 both from Lord Napier -and Mr 

 Mair in 1825. 



Magnolia conspicua. 



Flowered well against the open wall in 

 a sheltered situation towards the end 

 of March, and its fine large flowers 

 bore without injury continued and 

 very cold weather. 



Maxillaria aromatica. 

 Gen. Char — Bot. Reg. fol. 897- 

 Spec. Char — M. aromatica; bulbo 

 ovato compresso, foliis numerosis 

 sequitantibus, scapis radicalibus, 

 unifloris, labello semicylindraceo, 

 lobo medio majore denticulato, la- 

 bello interno integerrimo angus- 

 tiori.
