of the marine flora of the region; but the present paper, besides 
contributing much to our knowledge of species already found there, 
adds twenty-four, of which seven are new to science. This brings 
the total of species to 167 ; and if we compare this number with the 
corresponding figures for other regions, it must be borne in mind that 
the author, perhaps more than any other algologist, defines species in 
a very broad way, often including under one specific name several 
forms that are elsewhere considered distinct. 
Even without this allowance, however, the number must be con- 
sidered very high for an arctic flora. Two causes have contributed 
to increase the number — the careful study of minute epiphytic and 
parasitic forms, and knowledge of deep-water forms obtained by 
extensive dredging. 
Like its predecessor, the paper is illustrated by figures in the text ; 
the latter is in French, however, instead of Danish ; a change that 
will be regarded as an advantage by its readers, unless they are 
ultra-patriotic Danes. F. S. COLLINS. 
Botanical Notes. — The localization of the alkaloid in Cinchona 
as been investigated by Dr. Lotsy, whose studies of Taxodium 
are familiar to American botanists, and who is now connected with 
the laboratories which the Dutch government has established in its 
Indian colonies, for the investigation of the quinine-producing trees. 
His conclusions form No. 1 of the laboratory contributions of the 
Gouvernements Kinaonderneming, printed at Batavia, a quarto of 128 
pages, containing two folding plates and accompanied by an atlas of 
twenty colored plates of larger size. 
Professor W. W. Bailey, of Brown University, communicates the 
following observations upon a South African species, in which pro- 
terandry was previously recorded by the same author in 1886. 
“I have had a plant of Veltheimia viridifolia for some twenty years, 
and this year, after a long interval, it is blooming. The flowers, each 
of which has a long period of anthesis, are proterandrous, the stamens 
preceding the pistils several days in their development. They are 
slightly exserted, and the style, when finally it appears, is long 
exserted. The perianth is withering-persistent, and the raceme of 
some twenty or thirty flowers is over a month in blooming — perhaps 
two months in the development of its foot-long scape.” 
Boerlage’s Fora van Nederlendsch Indié, with Part II of the second 
volume, recently issued, completes the Gamopetala, including the 
families Oleaceze to Plantaginacez.
