The long, filiform peduncles remind one of C. laxiculmis, but, as 
Prof. Bailey has remarked, the colored leafless sheaths and the char- 
acters of the staminate spike indicate the affinity to C. plantaginea. 
The perigynia are about two-thirds as large as those of C. plan- 
taginea, which they much resemble (Plate 208).

Flowers in May. 
STEIRONEMA INTERMEDIUM N. sp. 
- Perennial; stem erect, 4-8 dm. high, slender, rather obtusely 
4-angled, glabrous below, minutely glandular puberulent above as 
are the petioles, pedicels and calyx; lower Jeaves 5-7 cm. long, 
2-4 cm. broad (the floral much smaller), from broadly ovate below 
to narrowly ovate-lanceolate above, acute at apex, rounded or 
more usually truncate, cuneate or subcordate, and unequal at base, 
margins entire, somewhat sinuate, minutely ciliolate, veins ae 
spicuous but not prominent, sometimes even slightly impresse®, 
often obscurely scurfy-puberulent, leaves otherwise smooth ; 
petioles slender, the lower 3-4 cm. long, ciliate only at the con- 
nate base as in S. radicans; inflorescence an open leafly panicle, 
the ultimate divisions corymbose; pedicels slender; 2-6 times as 
long as the flower; calyx 10-12 mm. in diameter, the segments 
lanceolate, very acute; corolla bright golden-yellow, 18-20 is 
in diameter, segments cuspidate; capsule about one-third shorter 
than the calyx lobes. "

In a genus like Steironema, of which the species are a a 
confluent, the making of new ones on any but well-marked an 
constant characters is not advisable. The plant in question 15 5° 
distinct from any other form known to me, however, that I have 
no hesitation in giving it specific rank. The fact that it holds 
its characters over such a wide range is strong evidence of its 
validity. : : 
The name chosen for the species indicates its intermediate pos! s 
tion between Svteironema ciliatum and S. radicans. — Apart fro wi : 
the erect habit, the general appearance of the plant suggests MmOre —
