moss along aged and decayed windfalls in the forest. The calyx, 
with its lobes, pedicels, and scape, lengthen and stouten and 
amplify remarkably in seed. For this, owing to our enforced 
flight, we had to depend on specimens hurriedly dug up in the 
woods of Satanee, carried off in boxes, and grown on to ripen 
in the hot backyard of the Yamen at Siku. On this, accordingly, 
I build no great hope ; but plants have been since sent, which I 
trust may be enough to introduce so really first-class a Primula 
into cultivation, where it has all the look of thriving robustly 
and permanently. So far, it is the only general woodland Primula 
exactly taking the place of P. acaulis in its limited region. 
[Specimens of what appears to be this are in the Petrograd 
Herbarium as P. membranifolia, quite a different thing. There is 
no trace left of either plant or seed now (1916).] 
Primula scopulorum sp. nov. No. 2 (F 39) is very hard to place; it 
is best pictured by imagining a scape of soft-mauve P. hirsuta 
applied close upon a rosette of P. farinosa or P. frondosa. It is 
a charming species, and abounds on cool, mossy rocks and cliffs 
in the woodland zone of the Chago-ling-Satanee Alps, pene- 
trating across to Thundercrown, where it is commonly seen in the 
boulder-crevices from 8,000 feet to the actual gaunt summits of the 
Ridge, and there it is still in bloom at the end of June — long after 
the May-flowering specimens of Satanee have passed into seed- 
It is purely a saxatile plant of cracks and crannies, and dies away 
in autumn to a beautiful fat knop of creamy-white, the same soft 
powder on the reverse of the foliage finely enhancing the blossom 
in spring. It is only at its best, goodly in form and rosette and 
freedom and flower, in the dark chines opposite Satanee ; about 
Chago-ling and throughout its strange distribution over the open 
flanks of Thundercrown it seems to miss the cool and mossy 
dampness of the woodland cliffs, and is universally thin and 
starved in growth, with only two to three blooms to a scape, 
instead of the possible eight that it can attain to in the moist 
and dark sub-alpine river-glens of Satanee. 
Primula riparia sp. nov. No. 3 (F 33). [Specimens of this, in the 
Petrograd Herbarium, are included under P. diantha.] It is a small, 
dainty clump, with gracious little scant umbels of mauve-crimson 
blossom ; three tufts were first seen on a steep, grassy rill-bank 
above Chago on May 6, and then a whole bank, cool, and over- 
hung with slight coppice, was seen studded with delicate specimens 
on the descent from Chago to the Satanee River on May 8. It 
proved impossible to get either seeds or plants of this — a failure 
with which I am glad to compound for success with so many 
more brilliant and important species. 
Primula sp. No. 4 (F 40) is interesting, as being almost certainly the 
plant previously recorded from Kansu, with marks of interroga- 
tion, as the Alaskan P. Loczii. In my experience it is confined 
to the district round . Gahoba, where, on the high moorland ridges
