occasionally united at base, is a marked characteristic of S. laswJepis, and 

 it is not inipr()l)al)le that S. Piperi will he found to varj^ in the direction of 

 that species. It seems . . . to combine the characters, of . . . »S. Uoolcerlana 

 und lasiolepi% wliile abundantly distinguished from both/* 



I have seen liebb's tj^:)e hi Herb. C, and I find that the capsules are 

 not *' smooth " as said in the original dcscrij)tion and repeated by IJali, but 

 sliglitly hairj' at apex. This is also true of si)cvimens collcctcil l>y Pii)er 

 and preserved in Herb. G., marked by the collector '' dui)licatc lype mate- 

 rial/' The filaments in both specimens are somewhat united and hairy 

 at the base. 



This si)ecies much reseml)les S. Ilooheriana var. laurifoUa as already 

 stated. It also reminds me of what is called S. lasiolcpis var. iiifjclovii of 

 Washington and Oregon. Unfortunately I am not well enough acquainted 

 with the Cordafae-group to which the last variety belongs. Therefore, I 

 do not wish to express to-day a definite opinion on the taxononiic value and 

 the true affinity of S, Piperi. Some of the specimens I am going to quote 

 seem to represent a good species^ while as a whole the matcrhil wliich I have 

 seen is by no means sufTicient to decide whether it consists of fonns of dif- 

 ferent (partly hybrid) origin or can be regarded as belonging to one \ aria- 

 blc species. The fac^t that some si)eclmens point to the Cordalae and some 

 to S. Ilookeriana may be explanied by the hybrichzation of N. Piperi w^ith 

 the last species and witli fonns of the Cordatae. After all [t needs a careful 

 study in the field. I liave not yet seen well matured fruits which are said 



by Ball to measure G to 7 nun, in length. The following spcchncns have 



been ^qqu,

 states that in Orc^gon it ranges "soutliward through the AVillainette Valley to Curry 

 County." 



7. S. laurentiana Fcrnald in Rhodora ix. 220 (1907). — I have seen the 

 type material and besides that only one specimen from southern Labrador. 

 The male plunt is not j^ct known, and this species needs further investiga- 

 tion. There are a few statements in Fernald's original descrii)tion ^^ hirh ac- 

 cording to my observation are not quite correct. lie says that the fruiting 

 aments measure up to 9 cm. in length while I Iiave not seen any longer 

 than 7 cm., and the style is not very short (brcvissmio) but up to 1 mm.
