BOTANICAL NOTICES OF NEW PLANTS. 



mountains in South America, at an elevation of about ten thousand feet above the level of the 

 sea. It has also been sent by Mr. Tweedie from the hills of Monte Video, and more abun- 

 dantly from the Sugar-loaf mountain of Maldonado. The seeds were collected by Mr. Tweedie, 

 at Tandil, and were sent to the Right Hon. the Earl of Arran, in whose garden the plant was 

 first raised, and from whose drawing the present figure has been taken. 



This charming species emits a most delightful odour, resembling the jasmine, which is most 

 powerful at night, diminishes at mid-day, and increases again towards the evening. It is of easy 

 culture. Bot. Mag. 



SCROPHULARINEiE. 



Collinsia heterophylla. Hook. Various-leaved Collinsia. Bot. Mag. t. 3695. This 

 species of Collinsia is very near to C. bicolor, from which it is stated to differ by its lower leaves 

 being lobate, and the hairs on the calyx coarser, by the rounded (not retuse) crenate segments 

 of the corolla, by the subacute middle lobe of the lower lip, and by the nearly entire border to 

 the upper side of the throat ; the flowers are also larger. It is a native of America, and was 

 found by Dr. Nuttall on the Columbia. It was raised by Mr. M'Nab, from seeds transmitted 

 to him in spring last, by Mr. Buist, of Philadelphia, under the above name. Bot. Mag. 



MONOCOTYLEDONES. 



HiEMODORACEiE. 



Anigozanthus flavida, var. bicolor. Lindl. Two-coloured yellow-haired Anigozanthus. 

 Bot. Reg. N. S. t. 64. This plant differs from A. flavida in having a more divaricating 

 panicle, and scarlet ovarium. Bot. Reg. 



MELANTHACEjE. 



Zigadenus glaucus. Gray. Glaucus Zigadenus. Bot. Reg. N. S. t. 67. This is a pretty 

 plant, bearing flowers not unlike those of the genus Ornithogalum. It is a native of North 

 America, and extends from Canada and Kotzebue Sound as far as Arkansa and Oregon. Dr. 

 Gray saw specimens collected on the high plains near the rivers Platte and Multoromah. It has 

 also been collected near Lake Superior, by Dr. Torrey, and on the North-west coast of North 

 America, by Mr. Douglass, who supposed it to be Z. elegans of Pursh. 



It is figured from a specimen in the collection of Messrs. Chandler and Sons, of Vauxhall, 

 which was exhibited at one of the meetings of the Horticultural Society in Regent-street, where 

 it was much admired. It is a hardy perennial, flowering in July and August, and grows well in 

 either loam or peat, and is easily increased by seeds or division of the roots. The seeds should 

 be sown in March in pans, and placed in a cold frame or pit ; and the seedlings will flower in 

 the second or perhaps third year after sowing. Bot. Reg. 



ORCHID ACEiE. Lindl. MALAXIDEjE. Lindl. 

 Pleurothallis lateritia. Lindl. Brick-dust-coloured Pleurothallis. Foliis subspathu- 

 latis crassis ; scapo subflexuoso ; folio longiore ; sepalis lateritiis ; petalis sub aureis ; labello 

 subtriangulo. 



This new species of Pleurothallis is in the collection of George Barker, Esq., of Springfield, 

 who imported it from Mexico in the year 1837, and with whom it flowered for the first time in 

 last November, 1838. 



The genus Pleurothallis, from the almost daily introduction of species, is now becoming so 

 extensive as evidently to require revision ; and we cannot help thinking that a number of the 

 species at present retained, are not entitled to be considered more than mere varieties. Indeed 

 we have examined some in the above-named gentleman's collection, so closely approaching the
