Typical, well-developed specimens were collected in full flower on 
Aug. Ist 1905 and Aug. 3rd 1904. 
The leaves are oblong-lanceolate, the prominent middle vein on the 
under side does not reach the acute apex, the hair-covering consists of 1°, 
long, ciliate, simple or forked hairs at the margins, 2°, stellate hairs on 
the upper half of the surface of the under side. The stems are sparingly 
hairy with coarse, stellate hairs. Our specimens agree fully with the fig. 11 
of GELERT, Botan. Tidsskr., 21, 1898, p. 300.

Well developed flowering specimens of various forms were collected 
in the last days of July 1904. 
The explanation of what Draba glacialis Apams really is has caused 
much confusion among the botanists. I think that this is due mainly to 
the circumstance that later authors have not had occasion to examine 
Apams’s type. I myself have not seen it, nor I have had the original 
description at my disposal, but I think that the description in DE CANDOLLE’s 
Prodromus (l. c.) is correct, as he has seen the specimens. Where these 
are kept is not known to me, but hardly in St. Petersburg, as LEDEBOUR 
(l. c.) only quotes American specimens sent him by Hooker. 
Hooker (I. c.) has placed different forms under his D. glacialis and 
from him dates the confusion, as some of his forms belong to the form 
which I think is the true D. glacialis, others are the species which Hooker 
himself on the same page describes as D. oligosperma Hook. supposing 
that it has white flowers. Later Amerian authors, e. g. S. Warson (I. c.) 
have taken D. oligosperma as synonym of D. glacialis and have moved 
D. glacialis from the section Drabaea (Chrysodraba) to Aizopsis to which 
section D. oligosperma undoubtedly belongs. All this may be correct, if 
D. glacialis was rightly understood in this way — and my late friend
