to perfect that lucidness which we earnestly desire to attain, we shall end with a 
summary of the only means for deciding the individual marks of either Endogens 
or Exogens. To be thoroughly armed against mistakes, the examiner must 
never depend on one, or even two points, in the sketch we have drawn. Some 
grasses, for instance, branch most abundantly, and bamboos are said to throw out 
such astonishing numbers of lateral shoots, as to form an impenetrable phalanx to 
the weaker kinds of animals. Other Endogens have minutely -veined leaves; 
most Orchidace^e (which also belong to this sub-class) shed their foliage by a 
perfect disarticulation from the stem ; rushes have often a large portion of pith, 
and these are likewise Endogenous. It is not to be inferred from such exceptions 
that no universal rule can be established ; but solely that unless we inspect and 
compare every member wherein the peculiarities are in any degree palpable to the 
senses, we shall be in danger of falling into extensive and pernicious errors.

NEW AND RARE PLANTS FIGDRED IN THE LEADING BOTANICAL PERIODICALS FOR 
FEBRUARY. 
Bouvardia splendens. Although approximating greatly to some other 
Bouvardias^ this splendid plant has flowers of a deeper and more brilliant hue than 
any similar species known in British collections. It has narrow, lanceolate, 
acuminate leaves, which appear to be distant, and produced in whorls of three : 
the blossoms are arranged in terminal corymbs, being numerous, dense, and of a 
uniform rich vermilion, or scarlet colour. It flowered in the Edinburgh Botanic 
Garden in July and August 1839, having been obtained from the London 
Horticultural Society. There is a peculiarity in its propagation which deserves 
to be recorded ; it is, that Mr. M'Nab has failed in striking cuttings taken from 
the shoots, while he " has found it very easily increased by slips from the roots not 
half an inch long, and covered so as to leave the upper extremities only exposed 
and level with the surface." Seeds, however, will most probably ripen.

Catasetum Russellianum. This remarkable species has been named by Sir 
W. J. Hooker as a tribute to the departed worth of the late Duke of Bedford, it 
having been the last new plant that flowered at Woburn previous to His Grace's 
lamented decease. " In him, science and the arts have lost a steady friend and a 
munificent patron ; and botany and horticulture, in particular, have seldom had a 
more devoted admirer." The species was collected by Mr. Skinner in Guatemala, 
and sent to "Woburn in 1838. The pseudo-bulbs are not of an uncommon descrip- 
tion, being short, thick, and marked all round with transverse rings, denoting
