ir Verbascum Thapsus, and ends in a very large pyramidal raceme densely set with rosy 
irple-coloured flowers. Bot. 4150. 
Myo'porum serra'tum. a very close-growing bush, attaining, in its own country, from six 
eight feet in height, and clothed with light green broadly lanceolate leaves, serrated at the 
ges. “ In cultivation in Tasmania it becomes a very pretty round-headed shrub, whose flowers 
e succeeded by blue fruit. In our gardens it forms a neat bush, loaded with a profusion of white 
)wers, as large as those of hawthorn, and spotted with purple.’’ It bloomed in one of the green- 
(iises of the Horticultural Society’s Gardens last May, and is there gi’own in a sandy peat soil, 
'id copiously watered whilst developing new shoots. Mr. Gunn says that the plant is called in 
e colony ‘ Mangrove,’ and is very common in the sand close to the sea, where it grows in cora- 
|iuy with Acacia Sophora SLXid Leucopogon Richei.’' Bot. Reg. 15. 
f Onci'dium bicallo'sum. Introduced by Mr. Skinner from Guatemala, to the collections at 
I'oburn Abbey and at Knypersley. It has been described by Dr. Lindley as a species distinct 
iim, but bearing a close relationship to O. Cavendishianum. Sir W. Hooker considers “ the 
0 as forms of one and the same kind, and that the species is liable to considerable variation; the 
:ore especially as our O. pachyphtjllum, Bot. Mag., 307, is considered by Dr. Lindley a state of 
Cavendishianum. To me,” he adds, “ our present plant seems to correspond better with Mr. 
ateman’s original figure of O. Cavendishianum, than our O. pachyphyllum does.” (There 
:irdly appears more difference in the three, than may be seen in many other species of Orchi- 
iceae. In an ornamental view, one of them is quite sufficient in an ordinary collection ; the 
I 'esent, however, is the best.) Bot. Mag., 4148. 
Ornitho'galum margina'tum. Approaching O. refractum and exscapum,, but both those 
ecies have a white stripe in the middle of their leaves, which do not appear to be white-edged 
in this. It was given to the Horticultural Society by the Dean of Manchester, who had the 
lib from a correspondent. It was gathered on the Asiatic side of the Bosphorus. In a dry 
nation it will probably be hardy. The flowers appear in March and April, and the plant 
arcely reaches a foot high. Bot. Reg. 21. 
I Pentste'mon gentiano'ides var. dia'phanum. From the original P. gentianoides the present 
riety differs in bearing flowers of a rather larger size, “and almost colourless on the under 
le of the tube, which is moreover so thin as to be semi-transparent, and to allow the filaments 
be perceived through it. The calyx, too, is much more covered with glands than in the true 
ntianoides. The latter has by some dealers been called suffruticosum, a preposterous name, 
■id calculated to mislead ; for it is not more suffruticose than half the common herbaceous 
ants in cultivation.” It is also found under the name of P. grandiflorum, 'which is quite a different 
ecies. “ This is a very handsome and nearly hardy pei’emiial, growing two or three feet high 
any good rich garden soil, and becoming rather woody next the ground. It flowers freely from 
ily to Septembei’, and, like most of the Mexican species, is easily increased, either by seeds, or 
Sittings of the half-ripened shoots. It is no garden variety, but was raised from seeds received 
pm G. F. Dickson, marked from the Tierra Fria of Mexico.” (In the notice from which the 
love is abstracted, the variety is also called transparens, perhaps inadvertently.) Bot. Reg. 16. 
^ Ph^dranassa chloracra. “ One of the curious bulbs met with by Mr. Hartweg in Peru. It 
rcurred on rocks at the village of Saragura, near Loxa, at an elevation of about 9000 feet above 
le sea, and was supposed to be the long-sought Hamanthus dubiusoi Humboldt and Kunth. It 
jis removed from Hcemanthus and stationed in Phycella, by the Dean of Manchester. The 
- amination of fresh flowers has, however, showed that it constitutes a peculiar genus, tb which 
[i*. Herbert has given the name of Phoedranassa (it is to be presumed from phaidros gay, and 
I iassa queen). He regards it as an approach to Stenomesson and Pentlandia.” The Phycella 
tusa is another species of Phcedranassa, also discovered by Mr. Hartweg, “ on the arid banks 
the river Guallabamba, in the valley of San Antonio, in the province of Quito, at an elevation 
ii about 7000 feet above the level of the sea. As this was the place where Humboldt and Bon- 
Und found their Hcemanthus dubius, it is not improbable that it is of P. obtusa rather than of 
Joracra that this plant is a synonym.” Both species are greenhouse bulbs, flowering in winter 
d spring before the leaves appear. The flowers are between two and three inches long, of a 
ddish hue tipped with green, and have a drooping direction : they form an umbel at the top of 
tolerably stout scape. Bot. Reg., 17.
