renewed vegetation of their axis degenerate into spikes."^ Normal 

 J . dehilis matures in early summer and has 2 to 7 flowers in a head. 

 The late-flowering form at I^ime Rock, like the Ravenel plant, has 

 the heads mostly prolonged into many-flowered spikes, the longest 

 8 mm. long. 



Polygonum cristatum Engelm. & Gray. Abundant on a gravelly 

 bank, Lincoln. Formerly unknown east of Connecticut. 



Agrimonia mollis (T. & G.) Britton. Found at various spots 

 in Lincoln, in rocky (calcareous) open woods and thickets. Pre- 

 viously unknown east of Connecticut, where it is rare. The only 

 herbarium-label which I find recording the lithological character 

 of the habitat of A. mollis is one of Mr. A. A. Heller's, stating that in 

 Lancaster County, Pennsylvania, the plant occurs in limestone, a soil- 

 preference which it clearly follows in Rhode Island. 



Amphicarpaea Pitcheri T. & G. Very abundant and climbing 

 extensively to the height of eight or ten feet over shrubs, in alluvial 

 woods, near a lime outcrop at Lime Rock. The vines form a close 

 tangle covering perhaps an acre of ground, and when found were in 

 abundant and very typical fruit. This plant, which is generally 

 known from western New York to Missouri, Louisiana, and Texas, 

 is very clearly a member of the New England flora. Twice before it 

 has been reported, — from Winchester and Revere, Massachusetts, 

 and from near Bridgeport, Connecticut; but in his discussion of the 

 New England Leguminosae in 1900, Judge J. R. ChurchilP was 

 inclined to discredit the status of the species in New England. Tlie 

 Rhode Island plant is quite like material from the Mississippi Basin, 

 the margins of the pods being covered with stifle mostly retrorse hairs. 



Gerardli parvifolia Cha])m. ((7. Skinncriana of many authors, 

 not Wood. G. decemloha Greene).^ This beautiful coastal plain species 

 is not cited from Rhode Island by Judge Churchill in his Preliminary 

 List of New England Scrophulariaceae.* It occurs with other pine-

3 The plant of sandy soils near the coast, from Massachusetts to Florida and Louisiana, 

 should be called G. parvifolia Chapm., for it is clearly that species and not the plant 

 described by Wood as G. Skinneriana, with which it has been confused. The latter spe- 

 cies is a plant of the interior, from Ontario to Minnesota, Tennessee and Missouri, with the 

 rose-colored corolla-lobes rounded or merely emar^inate at tip and the capsule globose; 

 while the coastal plant, G. parvifolia, has the lobes of the bright-pink corolla obcordate 

 and the capsule oblong-ovoid.
