THE GENUS PLANTAGO IN HAWAII

winged or indistinct petioles. The glandular denticulation is the same in 
both varieties, but is less pronounced in the plants from Waikolu, which 
specimens are marked var. hirtella in Hillebrand's own handwriting in the 
Gray Herbarium. 
The plants along the banks of Kamoku stream formed dense clumps 
or stands several meters in width. In the early spring of 19 18 the writer 
revisited the exract spot, but not a vestige of the plants could be seen.

Plantago princeps Heller ms. in Gray Herb. 
Stem 120 cm. high, hollow, dividing at that point into five candelabra- 
like branches {teste Heller), with terminal leaf-clusters; leaves distinctly 
lanceolate to linear-lanceolate, about 30 cm. long, 3.3 to 4 cm. broad, bluntly 
acute at the apex, broadly sessile (15 mm. or more broad) at the base 
(petioles absolutely wanting), 11- to 15-nerved; nerves prominent on both 
sides, absolutely parallel and not converging, glabrous on both sides; 
spikes 50 cm. long, stout, glabrous; peduncle three-fourths the length of the 
leaves, densely flowered in the upper half; bracts longer than the calyx, 
acuminate; calyx segments oval, acute, half as long as the corolla; corolla 
tube long-exserted, the segments half the length of the part exserted; style 
glabrous or slightly pubescent; capsule nearly twice the length of the calyx, 
oblong, dehiscing at the middle; seeds (4) linear, shining, black.

This exceedingly interesting variety which Heller refers erroneously to 
Plantago Queleniana Gaud. {Quelena Heller), is almost worthy of specific 
rank. It differs from all other forms of PI. princeps especially in the broadly 
sessile, very long, lanceolate leaves, with absolutely parallel veins, a char- 
acter especially laid stress upon by Wawra in distinguishing the two species 
princeps and pachyphylla, and in the pyxidium, which is circumscissile at 
the middle and not at the base as in all other forms of princeps. 
The characters which force us to place this anomalous plant as a form 
of PI. princeps are the tall, branching stem and linear, oblong, black seeds, 
characteristic of that species. 
Heller's misplacing of this exceedingly interesting plant must have been 
due to lack of material with which he could compare his specimens, but a 
careful analysis of the descriptions of the various forms of PI. princeps 
should have convinced him that he had before him a plant of exceeding 
interest in so far as it is an intermediate between PI. princeps and PI. 
pachyphylla.
