1918] Macbride,— A new Species of Bladdernut Tey 
habit, absence of hairs between the nerves of the lemma, the less 
prominent intermediate nerves of the lemma, and the much smaller 
anthers, those of P. autumnalis being 1.3-1.6 mm. long. From P. 
refleca, P. paludigena is. distinguished by the more slender, less caes- 
pitose habit, narrower leaves, shorter ligule and smaller spikelets. 
The anthers of the New York specimens were purple or violet when 
fresh; this may prove to be a constant specific character. 
P. paludigena is apparently the plant described as P. sylvestris Gray, 
var. palustris Dudley, Cayuga Fl. 128 (1886). We have seen none of 
Dudley’s material, but his description and the stations cited indicate 
P. paludigena, which, however, differs in many characters from P. 
sylvestris. The latter species has much broader leaves; stiffer longer 
panicles, with the more numerous branches strongly divergent and 
becoming reflexed; obtuse pubescent lemmas strongly webbed at 
base and with the midrib pilose to the tip and the median nerves 
prominent; and longer anthers (about 1.3 mm. long). The validity 
of the Linnean Poa palustris makes a new name necessary for P. 
sylvestris, var. palustris Dudley. 
A NEW SPECIES OF BLADDERNUT. 
J. Francis MACBRIDE. 
In the fall of 1917, Mr. H. C. Brigham of the Walding, Kinnan & 
= Marvin Co., wholesale druggists of Toledo, Ohio, sent to the Gray 
oA erbarium pods and leaves from one of three bushes of Staphylea 
= which were growing in his garden of native plants and which he had 
transplanted from the woods some years before. In his first com- 
munication, dated Oct. 1, Mr. Brigham wrote as follows: “They 
[the shrubs] were very small, but grew rapidly, and one of them is now 
about twenty feet high, while the others are more than twelve feet 
in height. As soon as they began to blossom and bear fruit, I noticed 
a strong dissimilarity between one of them and the other two. These 
distinctions I will set down here as briefly as may be: 
“The ordinary form has a large, oblong, bright green pod, usually 
somewhat wrinkled. The odd form has a much smaller, pear-shaped
