seminibus ovoideis rubro-brunneis o.y mm. longis basi truncatis ; 
floribus d, sepalis 2 anguste spatulatis apice sparse pubescentibus, 
petalis perbrevibus nigroglanduliferis, staminibus 4, antheris quad- 
ratis non longioribus quam latis.— New Jersey : on the shore of the 
Delaware River near Cooper's Creek, 7: P. James, September, 1858 
(hb. Gr.); on the shore of the Delaware River, between high and 
low water mark, Camden, C. F. Parker, 7 October, 1877 (hb. Gr.). 
Both specimens of Æ. Parkeri were distributed as E. septangulare, 
but they differ from that species in their numerous heads scarcely 
4 mm. in breadth, and especially in the form of the fruiting head, 
which in Æ. Parkeri is campanalate at the base, the erect flowers 
being surrounded by an obvious and persistent involucre of their 
own length in the manner of a composite, while in Æ. septangulare 
the fruiting head through the widely spreading or even reflexed posi- 
tion of the outer flowers becomes ellipsoidal somewhat surrounding 
and obscuring the more or less deflexed involucre. The short thick 
pubescence, which in Æ. septangulare renders the head white is in 
E. Parkeri almost lacking. 
The species is obviously related to the southern Æ. Ravenelii 
(unfortunately omitted by Ruhland from his treatment of the family 
in the Pflanzenreich), but Æ. Ravene//ii is a much more slender plant 
with filiform peduncles and shining involucral scales. 
It is a pleasure to dedicate this species to the late Charles F. 
Parker, an able botanist, for many years one of the curators of the 
Philadelphia Academy of Natural Sciences.— B. L. RoBINsON, Gray 
Herbarium. 
Fon the privilege of using the excellent portrait engraving, which 
in our last issue accompanied the biographical sketch of the late 
Lorin Low Dame, the editors and managers of Ruopoma wish to 
express their gratitude to Mr. R. B. Lawrence, Chairman of the 
School Committee of Medford, Massachusetts.
