Canadian Plants I, Pag. 129. I, therefore, think it expedient to 

 give the following detailed diagnosis of this variety based upon 

 material collected from Saghalin. 



Differt ab specie typica caule viridi et herbaceo, saepe flaccidulo 

 et cacumine nutante — numqiiam rigido et lignoso — articulis rectis 

 non flexLiosis, ramis et pedicellis numquam divaricatis. 



Toliolum terminale imlgo petiolo longiore quam formae typicae, 

 vulgo 10 — iS mm. longo, praeditum. Basis folioli semper recte 

 abscissa vel vulgo angulum obtiisum formans, nee in petiolum 

 cuneatim decurrens sed petiolo distinctissimo. Tlores magni, bene 

 evoluti, petalis ad iA mm. longis duplo longioribus quam latioribus 

 deorsum ad basim versus aliquantulum productis, colore pulchre roseo. 



Tota planta pilis densiusculis et longis, calyx et folia non recte 

 evoluta pilis albis appressis vestita. 



The stem is as a rule fairly coarse, upright and straight, 

 often somewhat limp, not stifF and zigzag, and is always 

 green and herbaceo us, whereas the typical form is more 

 rigid and firm (lignified) and in colour frequently yellowish- 

 brown or often reddish. The whole plant is dark green. 



The terminal leaflet is generalh' longer petiolated, up to 

 10 — 13 mm. The shape of the leaflets, also, varles considerably, 

 from an egg-round oval, especially in those at the base, to a 

 completely rhomboid form; singly or more often doubly serrate, 

 less frequently with triple or quadruple teeth, or even bilobale, 

 more rarely round toolhed. 



Occasionally, the leaf may be imperfectly tripartite, giving a 

 digitate appearance, such as may now and again also be observed 

 in the typical forms. The hair growth is as a rule fairly close, 

 more or less depressed, often almost velvety, especially on the 

 upper part of the plant, in lea ves not ye\. fully developed, and 

 on the sepals, which may also in addition have glandular hairs 

 here and there. The flowers are large and well developed, the 

 length of the petals up to 14 mm., rounded at the top, rarely 

 somewhat marginated. The sepals are long, narrow and trian- 

 gular, often tapering at the top to a fine awlpoint about 1 mm. 

 long. The calyx at flowering time is not always so distinctly 

 recurvate as in the typical forms. 



In bud and with fully opened flowers 26 May, and in full 

 bloom 14 June on swampy meadows. 



Ledebour 1. c. states this variety only from »America arctica 

 ad sin. Kotzebue (Beechey ex Hook. et Arn.)«. It has not till 

 now been recorded from Saghalin, having probably escaped 

 observation. It is not at all mentioned from Eastern Asia either 

 by Maximowicz, Turczaninow, Fr. Schmidt, S. Korschinsky, 

 KoMAROV or other authors, nor does it seems to occur in the
