whom we are indebted for the opportunity of publishing it, 
and after whom we have named it, as a tribute to the zeal 
and almost unparalleled success with which he has devoted 
his attention to the introduction of new plants. 
We learn from Mr. Cameron, to whose care Mr. Bar- 
clay’s invaluable collection has long been confided, that it 
is a climbing shrub, supporting itself by the footstalks of its 
leaves, like the two other species of the genus. At the 
time our drawing was made, the plant was about six feet 
high, and growing in the open border; but as it had been 
trained to some pea-sticks, among which it had become 
entangled, it is probable that the length of its stem 
exceeded considerably the height it had attained. In the 
middle of October it was still covered with flowers, and 
had every appearance of continuing in beauty till the frosts 
should destroy it. This being the first season of its culti- 
vation, nothing is known of its capability of resisting cold; 
it is probable, however, that it will require the protection 
of a green-house in winter, and it is certain that it will be 
a hardy border-flower during the summer. It strikes from 
cuttings less freely than the other two species. 
We presume there can be no doubt of this being a 
genuine species of Maurandia; a point which cannot be 
absolutely determined without an inspection of ripe fruit. 
The immature capsules, which we have inspected, did not 
appear different from those of Maurandia semperflorens of 
the same age. í 
There is one peculiarity in this plant which, although 
extremely obscure, requires to be particularly pointed out: 
we do not know whether it exists inthe other. species 
or not; but it is so remarkable, that we trust we: shall 
be excused for describing it somewhat minutely... The 
testa of the unripe seed is of corky.consistence, and divided 
into numerous very unequal compressed: lobes, which. are 
largest at the back and edges. If one of these lobes be 
divided vertically, and placed under a powerful microscope, 
it will exhibit the appearance of bundles of interlaced spiral 
vessels, forming ducts from the inner substance of the testa 
to the apex of the lobes. These are, to-all appearance, so 
extremely like spiral vessels, that if it) were not known 
that those curious :‘organs are never found under such 
circumstances, an observer would be:led to consider: the
