Stemless; rootstock thickly covered with wool; leaves leathery, oval- 
oblong, ligulate-lanceolate, entire, 5- to ii-nerved, glabrous or tomentulous 
and puberulous, much shorter than the spike; spike elongate, densely 
flowered, the flowers woolly at the base (at last often glabrous); bracts 
and sepals ovate-obtjse or very obtuse; corolla lobes obovate, obtuse or 
very obtuse, or, after flowering, acute; ovules 2 to 4 in each locule. 
Plantago pachyphylla var. a mauiensis Gray, Proc. Amer. Acad. 6:

Caudex very thick, densely woolly with long, silky tomentum; leaves 
broad, 12.5 to 26 cm. long, 3 to 9 cm. broad, ovate, acute at the apex, 9- to 
ii-nerved, glabrous above, covered with a deciduous wool beneath, veins 
dark brown, conspicuous below, parallel, arcuate; petioles 2.5 to 15 cm. 
long, very broad (2.5 cm. or more at the base), the blade gradually narrowing 
into a short or long, broad petiole ; spikes numerous, robust, densely woolly, 
terete, up to 82 cm. long, 8 mm. in diameter; peduncle as long as or longer 
than the leaves; rachis shorter than the peduncle ; flowers arranged at short 
intervals in the upper half, woolly at the base; bracts and sepals ovate- 
obtuse or shortly ovate, with a broad, black median nerve, often pubescent; 
corolla lobes obtuse or acute; stamens and style long-exserted ; ovules in 
each locule 2 to 4, capsule dehiscing at the middle, obtuse at the apex;

Maui: U. S. Explor. Exped. on Mauna Haleakala (7,500 feet), type in 
Gray Herb.; Mann & Brigham, Haleakala, no. 428 Gray Herb.; Wawra, 
N.E. side Haleakala, no. 1912 Vienna Herb., spec. n.v. ; Hillebrand, Halea- 
kala, 6,000-8,000 feet, Berlin Herb., spec, n.v.; Puu Nianiau, slopes of 
Haleakala (7,000 feet), Rock, September, 1910, no. 8555 in the College of 
Hawaii Herb. (Under the latter number there are two specimens, one 
with shorter leaves but not oval, and resembling Mann's no. 428, which 
must undoubtedly be referred to this variety. The other specimen has 
much longer leaves with long, very broadly winged petioles, the spikes are 
very robust, and the sepals and bracts are pubescent while in the typical 
form these are glabrous.) 
Plantago pachyphylla var. mauiensis forma montis eeka Rock forma 
nova. 
Caudex as in P. mauiensis; leaves obovate-oblong or ovate-oblong, 
gradually narrowing into a very broad, winged petiole, up to 10 cm. long, 2.5 
cm. broad at the base; leaves densely matted below with thick, brown wool, 
with the exception of the clasping base of the petiole, nerves indistinct; 
spikes shorter than in P. mauiensis, robust, densely flowered and covered 
with matted wool; flowers embedded in the more or less deciduous wool; 
bracts and sepals oblong, acute or obtuse, as long as or longer than the 
corolla tube, the broad median nerve densely woolly; corolla lobes short, 
acute, and glabrous; anthers glabrous, exserted.
