J Chiefly from the foot of the Abor Hills, on 
the Dihong- 
Of Anoi/acea 1 shall only notice Sphoro- 
stemma, Blume. In this genus the connecti- 
vum IS highly dilated, and the cells oi the 
anthei at a considerable distance from each 
other; and yet from the arrangement of the 
stamina, bilocular anthers with contiguous 
loculi result 
It affords another instance of the existence 
of the peculiar tissue, until lately supposed 
to be characteristic of Gymnospermee. In 
addition to this singularity, its medulla is 
traversed longitudinally by bundles of dense, 
occasionally branched, woody fibre, which 
consists of a superposition or “ emboitement” 
of several layers. 
Cucurbicacece. Among these plants occur 
two genera which appear to be new, so far at 
least as the Prcdromus of M. De Candolle 
is concerned ; in which book the article on 
Cucurbitaceae (by M. Seringe.) appears to 
me to be very unsatisfactory. Of one of the 
above genera, 1 have only seen the male; it 
is remarkable for the involute, or rather gyrate 
involution of the petals. The second 1 pro- 
posecalling Actinostemma : it is chiefly re- 
iriarkaole lor the complete separation of its sta- 
mina; for the “ dehiscentia circumcisa’* of 
the fruit , and, above all, for the pendulous 
direction of the seeds. It appioaches in some 
points to Zanonia. I am not aware whether 
the peculiar nature of the arillus of this order 
has been explained or not ; it is a separation 
of that portion of the tissue originally sur- 
rounding and in close contact with the ovula. 
Hence it is a shut sac ; and hence, too, it is 
wanting in Actinostemma, in tvhich the ca- 
vity of the ovarium is not filled by a produc- 
tion from the placentae. 
Conariee, In Conaria, of which I have 
one species from the Abor Hills, the raphe 
is certainly external with regard to the axis. 
I have not been able to ascertain whether 
this ilepends upon any torsion of the funiculus, 
which Mr. Brown has stated to be the case 
in oilier instances of a similar anomalous situa- 
tion. 
Of Saurnreae. Houttuynia is the only 
example. This plant, which was originally 
described by I’hunberg, appears latterly to 
have been more misunderstood than by the 
original ciescriber. I have had no opportu- 
nity, however, of examining the work of 
TnuNBERGin which the plant is described. 
And 1 ought, perhaps, to expect M. Meyer, 
who has published** DeHouiluynia atque Sau- 
rureis,” with which work I am unacquainted. 
I find each flower throughout the spike, ex- 
cept perhaps the terminal one, to be subtend- 
ed by a very small bracte. Of these, the 
four lowermost, rarely only three, are highly 
developed and petaloid, forming the spatha. 
'I he number of stamina to each flower is, 
excepting those at the apex of the spike, al- 
most invariably three, and alw'ays equal to the 
carpella entering into the formation of the fe- 
male organ ; and of these the third is always 
next the axis. The terminal flower has from 
five to seven stamina ; the space between this 
and the uppermost friandrous hermaphrodite 
(?) flowers is occupied by an assemblage of
