NEW AND RARE PLANTS, 
THE NIGHT-SHADE TRIBE (sOL ANEiE). 
Datura Guayaquilensis. Guayaquil Thorn-apple. This annual species 
has nearly white flowers, which it produces about February and March in con- 
siderable abundance ; still it cannot be considered very desirable. It grows 
abundantly in moist places on the shores of the Pacific near Guayaquil. It has 
been treated in the stove, but it is thought that it will prove sufficiently hardy to 
occupy a place in the flower border during the summer months, Brit, Fl. Gar. 380. 
ONAGRARIiE. 
Clarkia Guauroides. Guara-like Clarkia. This is a showy annual, but not 
so handsome as C. pulchella^ or C. elegans. It was introduced by Mr. Douglas 
from Cahfornia, and raised in the Horticultural Society's Garden in the spring of 
1835. It is quite hardy, and grows well in common garden soil ; seeds ripen freely.

CLASS IL— PLANTS WITH ONE COTYLEDON (MONOCOTYLEDONEiE). 
the orchis tribe (orchide.^, epidendre^). 
L.^LiA ANCEPS ; var. Barkeriana. Mr. Barker's variety of Lselia Anceps. 
This variety of Lcelta anceps is a native of Mexico, whence it was procured by 
Messrs. Low and Co. It flowered for the first time in this country in the rich 
collection belonging to George Barker, Esq., of Birmingham. It is in general 
appearance like Lcelia anceps, from which it diff"ers in two of the opposite ribs of its 
four angled pseudo bulbs being smaller than the other two, in its petals being so much 
narrower as to difl'er materially in size from the sepals, and in the middle lobe of the 
lip being both narrower and' sharper. When the flowers first opened, the lilac of 
the sepals and petals was lighter, and possessed the transparent character of 
Cattleya lahiata^ but in a more striking degree. It will doubtless be easily cultivated 
upon the same plan as the Cattleyas. Bot. Reg. 1947. 
ORCHIDEJE. 
Trichocentrum fuscum. Brown-flowered Trichocentrum. This interesting 
species was imported from Mexico by Mr. Knight of the King's Road, with whom 
it flowered in July of last year. It is a stove epiphyte of easy cultivation. The 
plant grows much like Oncidium pumihcm, but the leaves are more acute. The 
flowers are very striking and pretty ; the petals and sepals are of a brownish green 
colour, while the lip is white, except a blotch of pink upon each side, from which a 
few streaks of yellow run through to its base. Bot. Beg. 1951. 
Monachanthus and Myanthus cristatus. In November 1836, His Grace 
the Duke of Devonshire was so kind as to put into my hands the extraordinary 
flower represented in the accompanying plate, which may be regarded as one of the 
greatest curiosities that our gardens ever produced. Accusto'med, as botanists now 
are, to the freaks and masqueradings of nature, and to the strangest departures from 
all rules at every step among orchideous plants, there is certainly nothing upon 
record to be for a moment compared with the case before us. It is that of a plant
