of very large and rather oval maroon berries on long pedicels, 
looking like a burden of small purple cherries along the graceful 
sprays in October. 
Cotoneaster sp. (F 404) has exactly the habit and foliage of 
C. congesta, but that the innumerable little fruits are black. It 
occurred on the coppiced pass above Mo-Ping. 
Cotoneaster sp. (F 405a) is an obscure species collected by Purdom 
about Chago, and pre-eminent in the remarkable size of its black 
oval fruit. It seemed a stiff and gawky bush of about 8 feet. 
(C. perpusilla abounds all over the lower Alps of Siku, but some- 
how I never arrived at getting any seed of it, it being so universal 
and profuse that one was always putting off collecting it till 
the " next time " that never comes.) 
Crataegus crenulata (F 329) is a most brilliant addition to the group of 
Cotoneaster angustifolia-Francheti. It makes a very stiff, angular 
bush of 5-6 feet, in foliage and habit exactly recalling Hippophae 
rhamnoides, a resemblance heightened by the stark stiffness with 
which the spur-like thorny laterals stand off from the few main 
shoots. All along the sprays and all along the laterals are borne 
profuse, well-furnished, and well-spaced bunches of the most 
blazing vermilion fruits in late October, far surpassing any effort 
of C. angustifolia, and making a wonderful effect against the 
sombre gloss of the narrow, dark leaves. I first sighted this as 
one solitary stunted specimen above Ban S'an at a field-side 
on the last summit of the loess before one breasts the mass of 
Thundercrown ; but subsequently we came upon it at home at 
one point in the cooler yet still dryish region of the Nan Ho, 
where, between Kwanting and Tan Ch'ang, it rose here and 
there in spouts of scarlet amid the scant scrub that clothes the 
rather arid hills beside the river, just below the great level where 
the stream diffuses in a hundred channels. It was never seen 
again ; nor can I promise much for its flower, seeing that, on 
our summer traverses of the valley, the shrub completely eluded 
our notice. [It also abounds through central S. Kansu and far 
down into Szechwan (1915).] 
Crataegus sp. (F 396) is a hawthorn of stately habit, either a stalwart 
bush, or quite a good straggling tree, with gnarled bark. The 
oxyacanthoid foliage goes of a burning deep blood-crimson in 
autumn, amid which the deeper crimson of the berries is almost 
lost. These, however, hang on very late into the autumn, long 
after the foliage is gone and the tree left naked. It begins in 
the high copses above M5-Ping, and abounds in fine form in the 
old sacred forest that overhangs Satanee. 
? Cremanthodium sp. (F 10) has pretty little kidney-shaped leaves, 
and single golden Senecio-stars on stems of 4-5 inches in March- 
April. It abounds in all cool and mossy places of the subalpine 
woodland throughout South Kansu, The seed, however, eluded 
our notice.
