in three rows, but more commonly only in two [figs. 2 and 3] 5 moreover, in P. Mandfhurica 
the ftomata are larger, clofer to each other, and more decidedly oblong, and hence more perceptible 
than in P. Cembra. The differences in this refpedt are indicated in figs. 4 and 5 ; in other refpeds 
the leaves are nearly the fame. In both the back is round and without ftomata; 
in both the fheath very foon falls off, leaving the leaves affixed to the branch, almoft 
without a fheath; and in both, while the fheath is young, it is compofed of two or 
three long and membraneous femi-tranfparent fcales of a 
| II 11H light fawn colour, loofely attached. 
We have not feen the male flowers, but the cones, 
although of the fame type as thofe of the P. Cembra, 
are fufficiently diftinH. The coloured plate of P. Cembra

has in the margin a figure of the cone of P. Mandjhurica , taken from 
an authentic fpecimen, which we owe to the kmdnefs of Profeffor Regel of St Petersbuig. The latter 
is confiderably fmaller, has not the tumid appearance of the former, and mftead of being of an ovate 
form, is fomewhat cylindrical. The fcales [figs. 6 and 7], for the moft 
part, have the apophyfis reflexed in a much greater degree than in P. 
Cembra. Their bafe is irregularly wedge-fhaped, and has either one or two 
deep cavities excavated in it for the reception of the feeds; or it would be 
more proper to fay that the feeds m their growth have made fpace for themfelves, adapting the 
fcales all around for their reception, fo that there is a deep hollow for each, not only at the bafe 
of the fcale, to which it belongs, but on the back of the fcale before it [fee figs. 6 
and 7]. There are feldoin two full-grown feeds to each fcale, in many cafes only 
one; but in the fcales in the middle of the cone—that is, thofe which are moft 
developed—there is ufually a large and a fmall one [figs. 8 and 9]. The apophyfis is fawn-coloured 
and rugofe, the covered part of the fcale of a redder brown. The feeds are dark brown, fmall, obtufe, 
gibbous, and wholly without wing. 
Profeffor Regel fays:—“Having examined numerous cones brought to St Petersburg by Maack 
and Maximowicz, I have acquired the convibhon that this Mantfchur Cembra fiom the regions of 
the rivers Amour and Ufur fully maintains the peculiar afpefit which eafily diftinguifh.es it from P. 
Cembra. It flowers in June, and fpecimens with ripe fruit were collected by Maximowicz in the 
middle of September.” 
It is to be obferved that the cone, although differing from that of the true Cembra, has the general 
charadler or type of that fpecies. It is, like it, thick, folid, and, if not actually pubefcent, covered with 
a fort of clofe down, which gives it an opaque, foft appearance and a flight bloom, which fomewhat 
reminds one of the bloom upon a plum or grape. This character is not fo well marked in the 
reprefentatives of the Cembra on the other fide of the Pacific (in Mexico and North-Weft America), 
and indeed is wholly abfent in at leaft one of them (P. fertilis of Roezl) from Mexico. 
Geographical Diftribution. —This fpecies is the reprefentative of the P. Cembra in the north-eaft of 
Afia. It is ftated by Pallas to occupy great trafils of country to the eaft of the Lena and in Kamtfchatka. 
It there covers rocky mountains, which are fo barren that no herbage of any kind will grow upon 
them. It is alfo found in the valleys, but equally maintains its ftunted charafiter there too. Thofe 
found on the mountains are more refinous, and doubtlefs harder. Profeffor Regel in his “ Tentamen 
of the Flora of the Ufuri Region,” tells us that it is the only kind found in the diftribt of the Amour. 
It is found on the middle Ufuri, on the right bank, near the promontory Uang-Boboza, on the granite 
hills about the mouth of the Bikia, on the Sumus ridge. It is met with clofe on the bank of the 
Ufuri in a very few places, and only on the right bank. It grows in abundance on all the mountains 
of the right and the left bank which extend at fome diftance from it: for example, Touke, Cymyr, 
Siadadyngya,
