ones; it has dense spikes of deep yellow flowers, and grows 
freely in any dry loamy soil, and flowers in June. It occurs in 
a wild state in various parts of the south of Europe and Barbary, 
on stony or rocky hills.-— Bot. jR eg. 55-46. 
Primulace^e. —Pentandria Monogynia. 
Cyclamen littoi'ale. Roots of this plant, collected, we believe, 
at the Lake of Como, were presented by Mr. Bentham to the 
Horticultural Society. It has short deep pink flowers, somewhat 
like those of C. count , and is as hardy as any of the sorts ; it 
thrives in sandy loam and leaf-mould, but can only be multiplied 
by seeds.— Pot. Reg. 56-46. 
Orciiidace/E. — Gynandria Monandria. 
Brassavola Rigby ana. This very singular plant was introduced 
from Honduras, by Mrs. McDonald, and by that lady given to 
E. St. Vincent Digby, Esq., with whom it flowered last July at 
Minterne, in Dorsetshire. Its huge yellowish white flowers are 
as sweet as those of Aerides odoratum, and the largest measure 
nearly three inches in diameter. The neck of the ovary, which 
is cuniculate in a remarkable degree, is full four inches long. 
The singular fringe that borders the lip is quite analogous to what 
occurs in B. cucullata and others, only it is here extremely ex¬ 
tended, so as to give the flower quite a shaggy appearance.— Bot. 
Reg. 53-46. 
Pilumna laxa. This new and very distinct genus of Orchids 
has been hitherto known only by the account given of it in the 
miscellaneous matter of the ‘Bot. Register,’ tor 1844, No. 74, 
where, speaking of the present species, it is remarked, that its 
general appearance may be understood by its having been mis¬ 
taken for a Trichopilia. Its flowers are produced in loose erect 
racemes, out of broad, obtuse, short, membranous, spotted bracts. 
The stalks and ovary are an inch and a half long; the latter with 
three very stout and strong ribs. The sepals and petals are a 
pale watery green, erect, linear-lanceolate, equal, faintly tinged 
with purple. The lip is cream-coloured, rolled round the column 
at the base, to which it is also united at the lower end. The 
column has a singular fringed hood, overlying the anther, and a 
nearly vertical stigma, closed in by fleshy inflected cheeks, In
