FERNALD. — CARICES OF SECTION HYPARRHENAE. 449 



plate was drawn was collected by Tuckerman at the base of the White 

 Mountains; and since it is necessary to distinguish the plant by a new 

 specific name {minor having been used too often as a varietal name to 

 be eligible) and since there is already a Carex Tuckermani, it is a 

 pleasure to commemorate the explorations and generous services of the 

 Crawford family, familiar to a long generation of visitors to the White 

 Mountains. This plant with which their name now becomes associated 

 is common in northern New England and about the Great Lakes, thence 

 extending far northward. 



The other plant with narrow thick perigynia is more puzzling. In 

 the dark brown color of its broad scales it is unlike the other forms 

 which have been referred to Carex scoparia. In fact, by different 

 students it has been referred with doubt to C. tribuloides, C. lepornia, 

 and C. foenea as well. Yet in its perigvnium it resembles only Boott's 

 C. scoparia, var. minor. This tall dark-spiked plant, which is common 

 in the region of Orono, Maine, has been collected by Professor Lamson- 

 Scribner and by the writer, but it seems to be unknown from other 

 regions. This fact immediately suggests that it may be an introduced 

 form, but a careful search through Old World material and descriptions 

 fails to show anything to which it cau be referred. It is, therefore, 

 here treated as a local species, taking the name of the town from which 

 all our material has been collected. 



One other form of the scoparia group should be specially mentioned 

 since, by an unfortuuate misinterpretation, it has already caused needless 

 confusion. This is Carex scoparia, var. moniliformis, Tuckerman. A 

 specimen in the Gray Herbarium from Tuckerman himself, is without 

 question a slender-spiked form of C. scoparia. The variety was so 

 treated by Francis Boott, in whose table 3G8 it is well represented. 

 Yet in his Preliminary Synopsis of the genus Professor Bailey treated it 

 without question as identical with his own C. tribuloides, var. reducla ; 

 and Professor Britton, following las lead, has since made the new com- 

 bination, (7. tribuloides, var. moniliformis (Tuckerman) Britton, for a 

 plant very different from that to which the varietal name was originally 

 applied. 



Carex tribidoides, Wahl., has been clearly treated by Professor Bailey. 1 

 C. Bebbii, Olney, however, which by him is reduced to a variety of that 

 species, seems to be as well marked as other members of the subgenus, 

 and it is here given equal rank with them. In its shorter, broader, and
