King Point. This beautiful little plant was in full flower on June 
goth, 1906. 
The numerous specimens collected are very large flowered: petals 
2—3 times as long as the obtuse, oblong sepals. Leaves are short, broadly 
linear, obtuse and with faintly ciliated margins; capsules (from the year 
before) about three times as long as the sepals; seeds flattened, with long, 
densely situated spinules, which are most developed on the margin oppo- 
site to the funicle (as REGEL says: semina discoidea, fimbriato-cristata). 
The whole plant low, cespitose, flowers solitary on short, densely glan- 
dular-pubescent stalks. 
A. macrocarpa has a closely allied species in A. arctica (STEV.) FENZL. 
E. REGEL (Pl. Raddeanæ, I, 2, 1862) has given an exhaustive treatement 
of all the East Siberian forms of Alsine. He says that the seeds form 
the main distinctive character between the two species in question, but 
that this character is very unpractical, as the specimens in the herbaria 
mostly have no ripe seeds. I quite agree with him in this: I have not 
seen any herbarium specimens of the two species in question with ripe 
seeds, with the one exception of the specimens from King Point, where 
I happened to find some few ripe seeds in the capsules from the year 
before the collecting. As described above these seeds of A. macrocarpa 
agree with REGEL’s description and also with his rough figure (Tab. VIII, 
fig. 17). The seeds in A. arctica are wingless and rough. 
Besides the seed character and other floral characters I distinguish 
A. arctica and A. macrocarpa from the following vegetative marks: 
A. arctica, leaves long-linear, subterete, only at the base with few 
and small ciliate hairs, otherwise glabrous or glandular. 
Å. macrocarpa, leaves short- and broad-linear, flat, obtuse, along the 
margins with shorter or longer ciliate setae; but sometimes the setze are 
very short and inconspicuous. 
Our specimens agree in all respects with REGEL’S var. Riederiana, 
as the ciliate setae of the leaves are very short and oftenest wanting in 
the upper parts of the leaves; but the original description by Purs# (l. c.) 
says only »margine ciliatise, so that probably Pursn's type is the same 
as REGEL'Ss var. Riederiana and not as his var. {ypica about which he 
says »folia ciliato-setosa«. 
As to A. arctica and A. macrocarpa in Hooker, Fl. Bor. Am, I, 
pp. 100—101, tab. 34, I believe that A. arctica, 8, grandiflora (tab. 34, B) 
is a form of A. macrocarpa, as the leaves are strongly ciliate along the 
whole margin; a definite decision is nevertheless only possible if ripe seeds 
were present.
