34 ERYTHEA. 



The Cyclopsedia was issued in parts, at uncertain intervals 

 between the years 1802 and 1819, "and on the completion of 

 the work, a set of title-pages was issued, bearing the date of 

 the last, namely 1819 for 39 volumes of letterpress, and 1820 

 for five volumes of plates." 



In spite of much laborious research in the large European 

 libraries there are yet some 26 parts to which Mr. Jackson 

 is unable to assign dates, but for 23 of these the yearoi issue 

 can be decided with tolerable accuracy as they come between 

 others to which dates have been assigned. There are 11 

 parts of very uncertain date, but of the remaining 48 

 (altogether there are 85 parts, including plates) the precise 

 dates of issue of 18 have been obtained, and those given for 

 the other 30 can be almost certainly relied upon. 



We cannot but regret that this article was not published in 

 a botanical journal. Small pamphlets are apt to be lost 

 sight of within a few years after publication, and are still 

 more apt to become scarce and inaccessible. — J. B. D. 



SHORT ARTICLES. 



Pelargonium anceps, Ait. — Miss Emily Harrison discov- 

 ered this plant growing along Eleventh St. in E. Oakland three 

 years ago; but it was not identified until the present year. 

 Specimens were sent to Prof. Trelease at St. Louis and he 

 pronounced them the above named species. This is an 

 addition to the flora of North America but can as yet hardly 

 be considered as completely naturalized, since it has not 

 spread from its original place of discovery. It is a native of 

 Southern Africa, that apparent centre for Pelargonium, and 

 has probably been introduced with some seeds or plants 

 from that region. • It is not sufficiently near the coast or 

 the harbor to be considered a ballast weed. — a. e.
