ScrRoPHULARIA MARYLANDICA L. 
Erect, mostly 5°-6° tall (3°-10°), large plants becoming 
widely candelabrate branched above, the branches sometimes 
reaching an expanse of 5°. Stem glabrous and shining, four- 
sided with rounded angles and deeply grooved or impressed sides, 
more or less acutely quadrangular above. Panicles terminal on 
stem and branches, often somewhat pyramidal, mostly about r*. 
long (6/-2°) and leafy at the base, glandulose above and in the 
cymes, the glandules purple, stalked or terminating minute hairs. 
Cymes racemose, numerous, rather close, widely spreading or as- 
cending, varying from short and contracted to loose and open, 
2's’ in length and breadth, the peduncles usually much shorter 
than the branches. Perfectly developed cymes are formed by the 
forking of the peduncle into two diverging, evenly zig-zag branches 
bearing at each angle aslender-pedicelled flower, a solitary longer- 
pedicelled flower rising from the angle of the fork. In many 
cases the structure is less regular, and more contracted cymes may 
be irregularly dichotomous. Cymes bracteolate throughout, the 
bracteoles subtending the pedicels mostly in opposite pairs, linear- 
subulate, spreading or recurved. Flowers few to many; on the 
lower cymes rarely less than 9-11 and frequently twice that num- 
ber. Leaves slender-petioled, deep green, rather thin and veiny, — 
glabrous above (with fine scattered hairs when young) minutely 
pubescent below (nearly glabrous to softly pubescent) often very 
large, reaching a length of 1° and a breadth of 6’, mostly ovate- 
lanceolate from a rounded or sub-cordate base, but varying greatly, 
from cordate-ovate and acute to lanceolate and acuminate with 
acute or narrowed base ; uppermost leaves often narrowly lanceo- 
late tapering to either end. The leaves vary also from regularly 
or irregularly serrate or dentate to coarsely doubly dentate-serrate 
or even sharply dentate lobed. Petioles long and slender, from 
\% to 34 the length of the blade, or longer in the lower leaves, 
becoming gradually shorter in the upper leaves, ciliate-pubescent 
along the upper side, sometimes glabrate; nodes of the stem be- 
tween the petioles often ciliate-fringed. A fascicle of smal] leaves 
ora single pair, often quite rudimentary, occupies the axil 0 
each cauline leat; lowest leaves of the stem large and fully de- 
veloped, on long petioles. Corolla ventricose-ovoid, puncticulate 
with pellucid glands, 3-4” long, 2-214” wide, little contracted 
at the throat, the lobes short, the lateral pair and the upper lip 
usually slightly spreading, the lobes of the upper lip short and 
rounded ; outside of tube green, appearing dull and finely cellular, 
the interior shining and with the upper lip mostly deep brownish — 
purple ; not infrequently the flower is nearly all greenish-yellow. 
Sterile stamen with its adnate filament deep purple, about 3f"" 2 
broad ; style filiform, scarcely enlarged at base. Calyx-lobes oF 
bicular to oblong, obtuse, scarcely margined. Flower-buds du
