10 TRANSACTIONS OF THE [oCT. 7, 



Hypericum virgatum, Lam. var. ovalifolium, ii. var. 

 Leaves oval, not more than twice as long as broad, mostly ob- 

 tuse, and varying to obovate. Pine-barrens of New Jersey. 



ViTis heptaphylla (Buckley). 



Anipelopsis liepta2)hylla, Buckley, Proc. Phil. Acad. Nat. Sci. 



1861, 450. 



The suppression of this species by Dr. Gray was, I judge, 

 quite unwarranted; and now, from abundant material, I feel 

 justified in contending for its specific rank, not from the mere 

 fact of its generally developing more than five leaflets (the Vir- 

 ginia Creeper has sometimes seven, as was first noted, I think, 

 by Mr. Meehan), but from other characters which are more 

 constant. Mr. Buckley pleaded forcibly for its recognition 

 nine years later (1. c, 1870, 136), remarking on its smaller 

 leaflets (comparing it with the ordinary Virginia Creeper) and 

 its " cymose panicles," which flower at the end of April, while 

 plants of F. quinqvefolia in the same locality do not flower 

 until the middle or end of June. Specimens collected by Mr. 

 Tweedy, in 1879, in Tom Greene Co., Texas, maintain the 

 characters assigned by Mr. Buckley ; and the collections of 

 Wright, Fendler, Bigelow, Buckley, and this last, indicate a 

 wide range for the vine in western Texas. Young's "Flora of 

 Texas" maintains the species, and the recent monograph of 

 M. Planchon recognizes it as a variety at least, although that 

 author had not seen specimens. 



Acer saccharum. Marsh, var. nigrum (Michx. f.). 



A. nigrum, Michx. f. Arb. Amer. ii. 238. 



A. saccha7-inuvi, var. iiigi'um, Torr. & Gray, Fl. N. A. i, 



248. 



The adoption of Marshall's name saccJiariovi for the Eock 

 Maple in place of the more recent saccharinuni of Wangenheim 

 (the saccliarinum of Linnajus applying to the Silver Maple, as 

 recently remarked by Professor Sargent in '' Garden and Forest") 

 renders this readjustment of the varietal name necessary, if, as 

 I contend, it is to be considered a variety, and I have so used it 

 in the new "Flora of New Jersey." 



PhASEOLUS UMBELLITUS (Muhl.). 



Glycine umhellata, Muhl. in Willd. Sp. PI. iii. 1058 (1800). 

 Fhnseolus helvolus, Torr. & Gray, Fl. N. A. i. 280 (1838); 



Gray, Man. Ed. 5, 140, not of Linna?us. 



Phaseohis helvolus, L. Sp. PI. 724 (1753), belongs to the plant 

 which appears in recent writings as P. diversifolius, Pers. It 

 is therefore desirable to take up the oldest specific name avail- 

 able, which appears to be that of Muhlenberg.
