linear-oblong, obtuse or acute, about I cm. long, 2-3.5 mm. 
broad. 
Quite common on the south shore of Sneed’s Island, near the 
mouth of the Manatee River, No. 2432. 
PLUCHEA LONGIFOLIA n. Sp. 
Whole plant, particularly the inflorescence, pubescent with 
short villous hairs. Stem 6-10 dm. tall, branched at the summit; 
leaves crowded, erect or ascending, somewhat rough especially on 
or near the margins, denticulate or serrate, oblong or oval, those 
on the stem 6-16 cm. long, 2.5-5.5 cm. broad, the lower ones 
acute and sessile at the base, the upper ones truncate or rounded 
and slightly clasping at the base; inflorescence corymbiform, com- 
pact; involucres campanulate, 7-10 mm. long, exceeded by the 
slightly tawny pappus; scales of the involucre imbricated in 4-6 
rows, ciliate, the outer ones broadly ovate and obtuse or apicu- 
late, the innermost linear, acute. 
Common in an open swamp just back of Titusville, Brevard 
Co., No. 22y3. In the field the tawny white pappus makes the 
plant very conspicuous. 
PLUCHEA IMBRICATA (Kearney) (Pluchea foetida imbricata Kear- 
ney). Further observation of this plant in the field convinces me 
that it is worthy of specific rank, andso I raise it to that distinc- — 
tion. It often attains a height of 1-2 metres, being much taller 
than P. foetida, which rarely exceeds 6 dm. in height. The color 
of the foliage is much different, giving the plant a purplish hue. 
In P. foetida the leaves are a dull green. The most marked dif- 
ference between the two species lies in the time of flowering, P. 
foetida having matured its seed before P. iméricata is fairly in 
bud. There is a difference of some six weeks between the flower- 
ing periods. 
Rudbeckia bupleuroides Shuttlw. Collected in the flatwoods at 
St. Marks, Wakulla Co., No. 2538. I visited this place early in 
September, a little too late to secure good specimens of this rare 
composite. By diligent search I managed to obtain about a 
dozen presentable plants. It grows in the swampy part of the 
flatwoods, in company with Lacinaria spicata, ae as Ranenee, 
and E. virgatum.
