THE GENUS PLANTAGO IN HAWAII 
199 
branaceous, lightly erose, sometimes ciliate; corolla longer than the calyx, 
segments erect-spreading, lanceolate, acuminate; stamens inserted at the 
base of the corolla-tube, never exserted; filaments short; anthersoblong, 
hastate at the ba^e, brown; style very long, three to four times the length 
of the corolla; stigma short; capsule scarcely longer than the calyx, ovate- 
elliptical, mucronate, two-seeded in each lo'cule, circumscissile above the 
base; seeds black. 
In the valleys of the lower mountain ranges of Oahu (0-Wahu).

There are no specimens extant in the herbarium at Harvard of the typical 
PI. princeps Cham. Schlecht. Chamisso states that the stamens are 
never exserted while Hillebrand says long-exserted." All the varieties 
referable to this species have long-exserted stamens, with the exception of 
var. Queleniana (Gaud.) Rock which brings that variety closer to the species 
than any others. 
The typical form has not been collected by the writer, nor was it found 
by Wawra or Heller. Wawra lays especial stress on the venation of the 
leaves, the veins converging with the median costa below the middle, while 
those of PI. pachyphylla have the nerves free to the base and parallel to 
each other. 
One exception occurs in PI. princeps var. anomala, a new variety collected 
by Heller on Kauai; the leaves of that variety are those of forms of PI. 
pachyphylla while the seeds are linear-oblong and black as in PL princeps. 
The stem of the new variety is four feet high and branches in a candelabra- 
like manner, while PI. pachyphylla is stemless. The new variety is appar- 
ently intermediate, connecting the two species, or it can be looked upon as a 
new species; the writer prefers the former interpretation. 
Chamisso also says "style glabrous " ; the style in the specimen examined 
is hairy, as in all the varieties of the species. Wawra's statement that the 
capsules of variety laxifolia dehisce at the middle is incorrect. 
The only constant character for PI. princeps is the linear-oblong, black 
seeds. Nervature and branching habit are not constant characters, as 
stemless plants appear in PI. princeps and the nerves of PI. princeps var. 
anomala are not converging as in all other varieties; the dehiscing of the 
capsule is also not to be relied upon as a specific distinction, for an exception 
occurs in the last mentioned variety. From all this it may be seen that 
Plantago princeps is probably the older of the two species. 
Plantago princeps var. Queleniana (Gaud.) Rock. 
Plantago Queleniana Gaud. Bot. Voy. Uranie 445, t. 50. 1826. 
Stem woody, erect, simple, terete; foliose at apex; hairy or woolly all 
along the stem, especially toward the apex ajid at the leaf -scars; leaves 
thick, subcoriaceous, oblong-lanceolate to oval-lanceolate, glabrous on both 
sides, acute or sub-acuminate at the apex, gradually narrowing at the base,
