22 Rhodora [January 



ters. Sir J. D. Hooker, Fl. Brit. India 4: 295. 1884, assures us that 

 the plant lacks distinctness — "I cannot distinguish it as a variety 

 even" — and in confirmation of his statement that "the seeds vary 

 much in depth of pitting," it may be mentioned that Reiclienbach's 

 plate cited by Boissier as illustrative of true biloba shows seeds deeply 

 rugulose. Our plants seem quite intermediate, with the leaf-breadth 

 and leaf-serration of biloba, but with the pedicels tending slightly 

 to recurve and with the seeds and style as described for campylopoda. 

 They match well a specimen of Boissier's collected at Roscheya, 

 Syria, May, 184G, and named by him Veronica campylopoda. 



17. Veronica hederaefolia L. 



Veronica hederaefolia L., Sp. PI. 13. 1753. "Habitat in Europae 

 ruderatis." Diagnosis quoted from Linne, Fl. Suec. 7. no. 18. 

 1745, where the plant is said to occur "in Scania [Sweden] campestri 

 in ruderatis ad urbes & pagos." Specimen from Sweden, from her- 

 barium of Per Larson, seen in Herb. Columbia University. 



(?) Veronica rcniformis Raf. in Med. Repos. New York 6: 300. 

 1808. "In New Jersey fC. S. Rafinesque in 1803-4]." I am unable 

 to be certain of the identity of this from the short description: "stem 

 procumbent, branched ['branded'], leaves sessile, reniform, hairy, 

 entire, flowers axillar, solitary." It is possibly V. hederaefolia L., 

 in which case the petioles must have been so short as to be unnoticed, 

 or V. arvensis L., with unusually obscure serration of leaf, or else 

 some introduced species not since reported from America. 



Orchards and roadsides, occasional from New York to North 

 Carolina. Introduced from Europe.

THE NORTH AMERICAN REPRESENTATIVES OF SCIRPUS 



CESPITOSUS. 



M. L. Fernald 



The common sedge, Scirpus cespitosus L. 1 which forms conspicuous 

 wiry tussocks and often the dominant turf in the acid tundra and 

 barren regions of the North and in America extends southward to the 

 eastern coast and the mountains of New England, the Adirondacks, 



1 The name was originally published by Linnaeus as cespitosus and there is, there- 

 fore, no need to alter it, as is often done, to caespitosus.
