240 FIELDIANA: BOTANY, VOLUME 28
latis glabris; antheris anguste oblongis, 5.5-8 mm. longis; ovario
pubescent! pallido viridi; capsulis ovoideis, 1.5-2 cm. longis; seminibus
alatis, late ovatis vel suborbicularibus pallido brunneis, 3-3.5
mm. longis, a la ca. 1 mm. lata.
Type in herb. Chi. Nat. Hist. Mus., collected in Bonne tia roraimae
forest on southwest-facing shoulder, Ptari-tepu/, state of Bolivar,
alt. 2000-2200 m., November 2, 1944, Julian A. Steyermark 59766 (2
sheets), "matted on mossy exposed top of big shoulder; flowers faintly
fragrant, arising near base of plant; 2 outer sepals rose-pink at
base, otherwise greenish-white; a midline of pink or rose on outer
sepals; 2 inner sepals white within; rachis wine red as is scape; leaf
pale green with suffusion of wine purple-red, either one color massed
or in splotches; leaf tip with incurved purple-red appendage".
Additional collections are: in swamp on open level portion of
plateau on southeast-facing slopes, Ptari-tepuf, alt. 1600 m., November
1, 1944, Steyermark 59657; vicinity of "Misia Kathy Camp", on
mesa between Ptari-tepuT and Sororopan-tepuf, alt. 1615 m., November
15-17, 1944, Steyermark 60242', and along moist base of east-facing
high sandstone bluffs, Ptari-tepui, alt. 2410-2450 m., November 7,
1944, Steyermark 59934.
It may be noted that considerable variation occurs within this
species. For example, Steyermark 60242 has the pedicels slightly
puberulous on one side and glabrous on the other, whereas in the
other collections cited the pedicels are glabrous throughout. Moreover,
the size of the sepals varies in length and width, depending in
part on their age or development. The bracts subtending the pedicels
may be obtuse, but usually have a short or elongated cuspidate apex.
The appendages of the lids also vary in size, as do the pitchers
themselves. The Steyermark 59934 collection is a good example of
how robust this species may become under certain favorable growing
conditions induced by a combination of abundant moisture and shade.
In every way it is larger and more luxuriant than the other collections
cited. It was found on moist bluffs where seepage occurred, growing
in mats of Sphagnum oxyphyllum moss. It has larger more elongated
pitchers with longer hairs within, longer peduncles with larger and
more numerous flowers, and larger sepals. Despite these differences
it cannot be considered more than a vigorous individual likely to be
found in any group of plants where moisture affects more vigorous
growth and enlarged parts. In details of morphological characters
this luxuriant specimen, in all respects, is identical with that of
typical H. heterodoxa.
In the living condition H. heterodoxa is a very striking and colorful
plant. The pitchers are usually pale green with a suffusion of winepurple-red
color, either the one color massed or occurring in splotches,
or the lower part of the pitchers may be purple-red with the upper
portion pale green. The inner surface may be pale green within, but
also may have a dark brown-purple coloring within in the cup portion
