near the canal at First lock, June 9, 1897, The flowers are single and 

 borne on leafy -bracted axillary peduncles after the manner of R. pedun- 

 culata Torr. The c&\\x segments, however, are lanceolate, not awn-like, 

 and the bracts, though much larger, have about the form of those found 

 in the flower clusters of R. strepens. 



689. Ruellia ciliosa Pursh. 



My material includes a simple-stemmed cinereous plant found in dry 

 woods, the calyx-segments very hirsute, and a coarser plant with spread- 

 ing and geniculate-ascending branches, found in open and moister 

 ground, with the calyx-segments less hirsute. 



*373a- Oldenlandia uniflora L. 



Bennings, low ground toward the river swam]i. August 29, 1899. 

 376. Galium Claytoni Michx. 



Eastern Branch Swamp. Doubtless the (/. trifidum of Ward's Flora. 

 *382a. Galium tinctorium L. 



South Arlington near Cowdon's station. June .l, 1898; near Silver Hill, 

 May 26, 1899. 



*620/). Asperula arvensis L. 



A single specimen found on dumping ground in 1897 or 1898. 

 *363a. Viburnum molle Michx. 



Kenilworth, June 11, 1899; also at First Lock, near Tenleytown Junc- 

 tion, in Terra Cotta swamp, and near Eckington. I present this name 

 with great confidence, notwithstanding the fact that the stellate pube- 

 scence in our plaiit is almost obsolete on the under side of the leaf and 

 often scanty elsewhere. It holds out best on the petioles of the upper 

 leaves and on the peduncles. In one collection from Terra Cotta there 

 are remains of a soft stellate pubescence in the axils of the veins on the 

 lower leaf surface; but usually the pubescence in this situation appears 

 simple and undistinguishable from that of V. dentatum. A specimen 

 came to the Department of Agriculture from near Baltimore with a thin 

 soft stellate pubescence on the whole under surface of the leaf. The 

 pubescence on the petioles is stift' and very dift'erent, although also 

 stellate. In two distinct cases this species was found flowering when V. 

 dentatum was advancing into fruit. In one instance dentatum seemed to 

 be blooming late. I have not fully verified the fruit characters, but the 

 drupe seems larger than the V. dentatum. 



*36oa. Vibunum cassinoides L. 



A bvish fovmd in the sphagnous ground at Takoma Park was in flower 

 while the more common nudum was in bud, and being in other respects 

 dift'erent from that species, appears fairly to belong to V. cassinoides. 

 365. Triosteum angustifolium L. 



I have had one or two specimens from the railroad level at Glen Echo. 

 369. Lonicera Japonica Thunb. 



Found near Naucks with decidedly red flowers. 

 383. Valeriana paucifiora Michx. 



Abundant on Plummer's Island as well as on High Island.
