120 BOTANICAL GAZETEE [AUGUST 
amplectens.”’ ‘To those “‘formas ambiguas”’ belong the 3 varieties 
(subphylicifolia, subreticulata, and subpolaris) proposed by ANDERS- 
SON in 1858, which I have not yet been able to interpret correctly 
- owing to lack of the type material. 
In the Prodromus, ANDERSSON created a S. Pallasii with the 
var. crassijulis (Trev.) and var. diplodictya (Trvt.), and mentioned, 
strange to say, the type of PALLAs under the last variety, while he 
is using the name S. arctica Pall. to cover a multitude of forms 
including his var. nervosa, Brownei, groenlandica, petraea, and 
taimyrensis. He excluded from his S. arctica, therefore, the forms 
of the true S. arctica Pall., and combined under this name a series 
of very different things like S. altaica Ldstr. (recte S. torulosa Led.), 
S. anglorum Cham., S. groenlandica Ldstr., S. petrophila Rydbg., 
S. taimyrensis Trvt., and others. 
The first who attempted to clear up the Pallasii-arctica mixture 
of ANDERSSON was LuNDSTROM in 1877, in his interesting study 
previously mentioned. He confined S. arctica Pall. to its typical 
forms, and distinguished besides S. Brownei (And.) Ldstr., for 
which S. anglorum Cham. is the oldest name, S. groenlandica 
(And.) Ldstr., and S. altaica Ldstr., in which case he overlooked 
the priority of S. torulosa Led., a species founded on the same type. 
Lunpstr6m did not use CHAmIsso’s name because, following 
ANDERSSON, he referred S. anglorum to S. phlebophylla; see under 
S.anglorum. Another attempt to interpret properly S. arctica Pall. 
and S. arctica R. Br. was made by Bess (Bor. Gaz. 14:115. 1889), 
who, however, did not know Lunpstr6m’s work. Consequently he 
proposed another S. Brownii which, sensu stricto, corresponds with 
S. anglorum, a name likewise overlooked by BExBB, who refers some 
different forms to his Brownii. In 1899 Batt (Trans. Acad. Sci. 
St. Louis 9:89) mentioned that ‘the methods by which Professor 
ANDERSSON succeeded in greatly augmenting the then existing con- 
fusion in regard to S. arctica R. Br. and S. arctica Pall. have been 
exposed by Mr. Brss,” and stated that Bess had ignored the 
existence of LUNDsTROm’s earlier homonym; but BALL, in his turn, 
overlooked the name given by CHAmisso many years before. It 
was RypBERG who, in 1899, reinstated the name S. anglorum as the 
oldest correct name for S. arctica. Br., non Pall.
