FLORICULTURAL NOTICES. 
Isomeris arb5rea. At first sight, the flowers of this plant are said to be 
not very dissimilar to those of an Edwardsia , though chiefly so from their yellow 
colour. It was found by Mr. Nuttall in California, and transmitted by Mr. Buist 
of Philadelphia, to two of the Scotch establishments, in 1839. Kept in a green- 
house, it has not yet flowered ; but a plant having been placed in the stove at the 
gardens of the Caledonian Horticultural Society, bloomed in May, 1840. It has 
erect hoary branches, with trifoliate leaves, which gives it the appearance of a 
Genista. The blossoms are axillary, but likewise collected into a kind of raceme 
at the ends of the shoots. They are pale yellow, with a faint offensive odour, and 
have their large conspicuous capsule protruded considerably beyond them. “ Mr. 
James M‘Nab thinks that the flowering was promoted by his having forcibly 
retained the top in a depending position.’ 1 Bot. Mag. 3842. 
Malva lateritia. Mr. Tweedie, of Buenos Ayres, sent seeds of this plant from 
Entre Rios to the Dublin College Botanic Garden, where specimens blossomed in 
the open border, in September of last year. It is an herbaceous species, with 
prostrate stems, ordinary leaves, peculiarly long flower-stalks, and moderately large 
pale rosy-red flowers, which have a few darker streaks, and a blotch near the base 
of each of their petals. Doubtless the species is, from its character, adapted for 
planting in beds, but we should think it too luxuriant and diffuse to be very 
ornamental. Bot. Mag., 3846. 
Martynia eragrans. One of the handsomest annuals that have been intro~ 
duced for many years. It has a solitary stem, which begins to flower when at the 
height of one foot, and continues branching, and flowering from all its branches, till 
it forms a specimen of three feet high, and the same in diameter. The foliage is 
large and copious, and the flowers are borne in upright racemes. They remind us, 
in form and colour, of the beautiful Gloxinia rubra , being, however, of a somewhat 
darker red, with an apparently yellowish throat. It is a native of Mexico, from 
the neighbourhood of the Real del Monte mines, and was sent to Mr. Marnock, 
nurseryman of Hackney, by whom it has been flowered. The treatment given to 
Balsams is supposed to be most favourable. It may be raised and grown in a 
gentle moist heat, and bloomed in a cold frame or greenhouse. In addition to its 
great beauty, the flowers are highly fragrant. Bot. Beg. 6. 
Monolopia major. Described as growing naturally to only a foot in height, 
but constituting a rank and rather coarse annual, with two or three feet of stem, 
under British cultivation. It has strong stems, covered with whitish down, and 
manifesting a trifling disposition to branch ; the leaves are strap-shaped, but a little 
broader at the base, obtuse, and obscurely toothed. A large and deep yellow 
flower crowns each of the branches ; and these blossoms are noticed as showy, and 
as continuing in perfection most of the summer months. It was brought from 
California by Mr. Douglas, and sometimes bears the name of Helen ium Douglasii . 
It is most probably hardy. Bot. Mag. 3839. 
OncIdium macRantherum. We have no doubt that this is identical with a
