ASTER ARDENS 247 
33° Refracted form, with copious inflorescence subdichoto- 
mously divaricate and refracted ; highly disculiferous, 7. ar with 
most of the ramulars reduced to minute subsessile discs ig in. 
broad. With the type, Inwood and Bryn Mawr Park. 
6° A. ardens x A. axillaris; a probable hybrid "with succu- 
lent leaves, most of them still smooth when dry ; deliciously fra- 
grant; its short axillary inflorescences from the latter parent? its 
short broad leaves and very deep golden prominent disks from 
the idee parent ? 
yn Mawr Park, down Maple Av., Se. 16, '9g9. 
x3" Fa ardens x A, roscidus ; a probable hybrid with heads, 
rays and involucre resembling the former; in most other char- 
acters resembling the latter, including the following: Leaves 
small, broad cordate, with the narrow or winged petioles thick, 
spongy when dry, crenate-serrate, the upper ones and rameals oval 
to orbicular. Branching resembles chiefly the former parent. Hair 
scanty, occasional strigose hairs blackening and thickening at the 
tip, as if inheriting from the glandular hairs of A. rosczdus which 
grew near. Rays 6, in larger flowers 7, milk white; heads larger 
than in A. ardens, % in. across when fresh. Two plants, Bryn 
Mawr Park, Se. 16, '99. 
34. Aster scutiformis sp. nov. 
Cespitose slender plants along old stone walls or rock-slopes, 
with reddish-brown stems, serrate often decurrent-based leaves pale 
beneath, strong cornaceous cord-like veins, single-bunch or pin- 
nately-segregated inflorescence, chanfer and attenuate bracts, and 
scutiform lower leaves with broad tricurve base. 
Name L., scutiformis, shield-shaped. 
Fic. 46, plant from Mianus R., Ct., Oc. 15, '96, in hb. Bu. 
Stem reddish-brown, smooth, nearly erect, only moderately 
straight, terete, chiefly 177 ft. high, cespitose, sometimes filling 
extensive spaces. 
Leaves soft and smooth in earlier growth; becoming harsh 
and when dry minutely roughened, spongy-thickened and very 
firm ; deep green above, beneath a little whitened; its pale cast 
Lower leaves scutiform, z. e. escutcheon-shaped, somewhat cor- 
date-acuminate, with very shallow and broad tricurve sinus; the 
sides too much curved to be oblong; the greatest breadth a little 
above the base. Upper leaves oblong-lanceolate, short-petioled
