*43ia. Aster phlogifolius Muhl. 



Woodley Park, September 28, 189(5, not then recognized; Linnaean 

 Hill road, September 27, 1899; high land a mile or two from Great Falls, 

 Maryland side, October 3, 1899. 



448. Aster Novae-Angliae L. 



Abundant at points on the Conduit road. A fine growth also on the 

 Potomac flats in 1900. 

 -445. Aster puniceus firmus (Nees) Torr. & Gray. 



Tide marsh, Brick Haven, October 10, 1896; foot of First street south 

 east, September 21, 1897. 

 446. Aster prenanthoides Muhl. 



At various points up the river, from near Chain Bridge to Great Falls, 

 particularly across the canal at Cabin John. Never abundant. 

 *433a. Aster laevis Potomacensis Burgess. 



Connecticut Avenue Bridge, September 21, 1890: M street extended near 

 Eastern Branch, September 16, 1899; Leesburg pike near Difficult Run, 

 September 18, 1899. 

 42pa. Aster elodes Torr. & Gray. 



Very abundant in boggy ground. It is time to break the habit of call 

 ing this a variety of A. Novi-Belgii. 

 *42pa. Aster Radula Ait . 



Not only at the main Paint Branch station (here first collected by Mr. 

 H. W. Olds, I think.) but also a mile further east. In boggy ground at 

 Suitland, September 8, 1899, 1 found a much altered form with but one 

 to three heads, the leaves merely very finely scabrous. 

 442. Aster salicifolius Lam. 



Feeder Dam, Hunting Creek, and Great Falls. This is, of course, the 

 A. carneua or A. aestinut of Ward's Flora, but I have not met with any 

 thing to match the other name. 

 *443a. Aster paniculatus acutidens Burgess. 



Potomac fiats, October 9, 1897. 

 430. Aster lateriflorus (L.) Britton. (A. mixer of Ward's Catalogue.) 



Of the now recognized varieties, I think I can distinguish grandu 

 Porter, from Alexander's Island, and pendulna (Ait.) Burgess, from 

 Takoma Park. 

 450. Doellingeria umhellata (Mill.) Xees. 



Takoma Park, mainly near electric railroad junction, October, 1898, 

 1899. Rare. 

 450^. Doellingeria humilis (Willd.) Britton. 



Rather common in boggy ground, Terra Cotta, Bennings, etc. The 

 leaves of this species are not relatively as broad as might be expected. 

 This 1 suspect is wholly or in part the Diplopappu* umbettatua of earlier 

 record. 



449. Doellingeria infirma (Michx.) Greene. (Diplupappu* rornifoliu* 



of Ward's Catalogue). 

 The specific name doubtless refers to the procumbent tendency of one
