CAPRIFOLIACEAE. Honeysuckle Family
By E. P. Killip, U. S. National Museum
Shrubs, trees, or woody vines, rarely herbs; leaves usually
estipulate, opposite, simple or pinnate; flowers perfect, regular or
irregular; calyx tube adnate to the ovary, the limb 3-5-dentate
or lobate; corolla gamopetalous, rotate or tubular, the limb 5-lobed
or bilabiate; stamens usually 5, inserted on the corolla tube alternate
with the lobes; ovary inferior; style simple or lobed; fruit a berry,
drupe, or capsule, 1-6-seeded.
The Japanese honeysuckle (Lonicera japonica Thunb.) is culti-
vated in northern Peru, and may have become established.
It is known as "madreselva" and "brinco de dama." Lonicera
Caprifolium L., likewise known as "madreselva," is cultivated in
Cuzco according to Herrera.
Leaves pinnate; fruit 3-5-seeded 1. Sambucus.
Leaves simple; fruit 1-seeded 2. Viburnum.
1. SAMBUCUS L.
Shrubs or trees; leaves pinnate or bipinnate, the leaflets serrate
or laciniate; flowers small, in compound, flat- topped or thyrsoidal
cymes; calyx 3-5-dentate; corolla regular, rotate, 3-5-lobed; fruit
a small drupe, containing 3-6 one-seeded nutlets.
The name "sauco" is applied to species of this genus throughout
Spanish America. In Cuzco S. peruviana is known also as "rayan."
The leaves have excitant- properties, and from the fruits is prepared
a sirup which is used for throat troubles and in the cure of ulcers.
Leaflets, or some of them, pinnately parted, glabrous or sparingly
pubescent on the midnerve, subcaudate, the serrations rather
distant toward the apex S. mexicana var. bipinnata.
Leaflets not parted, pubescent on the nerves and veins beneath,
acute, acuminate, or subobtuse, closely serrate throughout.

In the account of the South American species of Viburnum we
combined this species with V. ayavacense. From the photograph now
available it is evident that the type is well matched by several Bo-
livian specimens, and it is perhaps better to consider the plant from
southeastern Peru and Bolivia specifically distinct from the one of
northern Peru and southern Ecuador.
Cornus peruviana Macbr. was later transferred to Viburnum by
Macbride (Trop. Woods 24: 29. 1930), but it is now considered to be
a true Cornus (see Standley, op. cit. 43: 16. 1935).

Jard. Bot. Geneve 17: 326-356. 1914.
Annual or perennial herbs, sometimes low shrubs, the roots with
a strong, characteristic odor; leaves opposite, estipulate, often
massed at or near the base, simple or compound; inflorescence
highly variable, capitate to laxly paniculate and repeatedly branched;
flowers perfect, polygamous, or rarely dioecious; calyx tube adnate
to the ovary, the limb inconspicuous in flower but becoming a pap-
pus in fruit, or wanting; corolla gamopetalous, funnel-shaped or
tubular, the limb spreading, 3-5 (rarely 6-8)-lobed; stamens 1-4,
inserted on the corolla and alternate with the lobes, usually exserted;
ovary inferior, 1-3-celled, one cell 1-ovuled, the others empty; fruit
indehiscent, 1-seeded.
This family consists of about 16 genera and from 350 to 400
species, and occurs mainly in the temperate zone and in the high
mountains of the tropics. Of the numerous species in Peru, many
are known from only a single specimen, and an adequate concept
of the family and of the lines of separation between the species is
impossible until further collecting has been done. In addition to
288 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIII
the native species, Valeriana officinalis L. and V. Phu L. are reported
from Peru by Ruiz and Pavon, and Centranthus ruber (L.) DC. has
been collected at Arequipa (Hinkley 32}. Plectritis samolifolia
(Colla) Hock is listed from Peru by Stuckert and Briquet (Ann.
Conserv. Jard. Geneve 20: 429. 1919), perhaps through error in
associating a Ruiz and Pavon Chilean specimen with Peru. The
following Ecuadorean species have been assigned to Peru through
faulty geographic knowledge: Valeriana alypifolia HBK., V. hirtella
HBK., V. microphylla HBK., and V. amphilophis Graebn.
Corolla 5 (rarely 6-8)-lobed (3-lobed in one species of Aretiastrum).
Leaves closely imbricate throughout the stem, 3-angled toward the
apex, connate, up to 5 mm. long; flowers solitary in the axils
of the upper leaves 1. Aretiastrum.
Leaves not closely imbricate, or in rosettes, flat, usually with a
distinct blade; flowers in clusters or, if solitary, borne on the
ultimate branches of a diffuse inflorescence.
Anthers orbicular or oblong, the filaments well developed and
usually exserted; stems or scapes generally elongate.
Fruit with the two empty cells equaling or larger than the
perfect cell; inflorescence few-flowered, the peduncles
long and slender 2. Astrephia.
Fruit with the two empty cells much smaller than the perfect
cell 3. Valeriana.
Anthers linear, sessile or subsessile; stems or scapes very short
and stout, the inflorescence usually flat-topped and much
broader than long 3. Stangea.
Corolla 3 (rarely 4)-lobed.
Tube of the corolla long and very slender, needle-like.
5. Belonanthus.
Tube of the corolla very short, stouter 6. Phyllactis.
1. ARETIASTRUM Spach
Low, cespitose shrubs, freely branched, the branches very leafy;
leaves small, coriaceous, closely imbricate, connate at the base,
entire; flowers few, solitary, hidden among the uppermost leaves,
sessile or short-pediceled, polygamous or dioecious, the tube funnel-
shaped, the limb 3-5-parted.

I have not seen the Humboldt and Bonpland specimen referred
to V. hyalinorrhiza R. & P., to which Hooker and Arnott assigned
the name V. Humboldtii. It presumably came from northern Peru,
and the description in the Nova Genera et Species Plantarum applies
well to the plant later described as V. Mathewsii. Graebner cites
(Bot. Jahrb. 3: 48) a Humboldt specimen from "Cusa," Peru, in
the Berlin herbarium as V. laevigata Willd., a manuscript name
first listed by Steudel. "Cusa" may be an error for Cascas, in the
Department of Cajamarca, a locality visited by Humboldt and
Bonpland.

This is one of the commonest species of Valeriana in the northern
Andes, and it is hard to believe that it was not described until
1845. V. laurifolia HBK., the identity of which has never been
fully established, may well be the earliest name for this species.
Valeriana Pennellii Killip, Journ. Wash. Acad. Sci. 18: 499. 1928.
Plant glabrous throughout, the root thickened, the stem erect,
40-45 cm. high; basal leaves 15-25 cm. long, including a petiole
longer than the blade, imparipinnate, the terminal leaflet ovate,
1.5-2 cm. long, obtuse, entire, the lateral leaflets 4-6-jugate, ovate
or ovate-lanceolate, 5-8 mm. long, 3-5 mm. wide, sessile, entire,
the cauline leaves 1 pair, similar but smaller, subsessile; inflorescence
spiciform, the upper heads sessile on the main axis, the lower sessile
on short branches; bractlets obovate-spatulate, 1.5-2 mm. wide;
fruit oblong, purple-spotted, obscurely 1-nerved on one face, nerve-
less on the other, the pappus 6-rayed.
Cuzco: La Roya, 4,400-4,500 meters, Pennell 13510 (type).
Valeriana pilosa R. & P. Fl. 1: 39. pi. 66, f. a. 1798. V. longi-
folia var. pilosa Wedd. Chlor. And. 2: 21. 1857.
Plant erect, about 30 cm. high, the rootstock thickened; stem
pilose, often very sparingly so or glabrescent; basal leaves numerous,
linear-lanceolate or narrowly spatulate, 10-15 cm. long, 0.5-1.5 cm.
wide, acuminate or subobtuse, tapering to a poorly defined, sheathing
petiole, glabrescent or faintly pilose, the cauline leaves linear, 1-4
cm. long; inflorescence narrow, trichotomously few-branched, the
flowers in dense clusters; bractlets obovate; fruit 1.5-2 rnm. long,
glabrous, obscurely 3-nerved on one face and 1-nerved on the other,

Mathews 66. Huanuco: Mito, 1812, 3352. Junin: Diezmo (Ruiz
& Pav6n, type).
In the specimens cited above the leaves vary somewhat from
those of the Ruiz and Pavon illustration, and the indument is so
scant that the specific name pilosa is scarcely appropriate. Mac-
bride 3352 has leaves up to 20 cm. long and 2.5 cm. wide, thus being
intermediate between this species and V. Weberbaueri, and his No.
1812 bears a strong similarity to V. sphaerocephala.
Valeriana pinnatifida R. & P. Fl. 1: 40. pi. 69, /. 6. 1798.
An erect herb, 30 cm. high or more, glabrous throughout except
the pubescent nodes and fruit; root tuberous; basal and lower
FLORA OF PERU 309
cauline leaves petiolate, ovate or ovate-lanceolate, entire, irregularly
crenate-dentate, or pinnatifid, up to 20 cm. long, including the
petiole, and 6 cm. wide, membranous, the upper cauline leaves
sessile, pinnatifid, the segments often toothed; inflorescence cymose
or cymose-paniculate, the flowers clustered, polygamous, the stami-
nate with a limb about 2 mm. wide, the limb of the others about
1 mm. wide; fruit flattened, broadly ovate, about 2.5 mm. long and
2 mm. wide, densely pilosulous and purple-mottled on both faces,
the pappus 10-rayed.
Lima: Lima, Ruiz & Pavdn (type); Nation in 1862. Amancaes,

Expedition. Matucana, 2,400 meters, 146. Junin: Huariaca, 2,900
meters, 31 01.
This species has often been confused with V. interrupta, probably
because the leaves of that species often -closely resemble those
shown in Ruiz and Pavon's illustration of V. pinnatifida. The
Pennell and the Mathews specimens very closely correspond to the
original description of the lowest leaves being entire; they have
broadly ovate, densely pubescent fruits, which may serve as an
additional differentiating character.
Valeriana plectritoides Graebn. Bot. Jahrb. 37: 441. 1906. V.
oligodonta Killip, Journ. Wash. Acad. Sci. 21: 351. 1931 (?).
Root thickened; stems few or numerous, erect, up to 30 cm.
high, essentially glabrous; basal leaves long-petioled, the blades
ovate to broadly rhombic-ovate, up to 5 cm. long and 4 cm. wide,
obtuse, gradually or subabruptly narrowed to the petiole, irregularly
sinuate-dentate, crenate-dentate, or denticulate, flabellate-nerved,
glabrous or sparingly ciololate, membranous, the cauline leaves
lanceolate or subrhombic, subsessile; flowers in dense, subglobose
heads terminal or in long-peduncled, axillary cymes or interrupted
spikes; bractlets obovate or linear-spatulate, about 1.5 mm. wide,
pale or rufescent; flowers polygamous, the staminate ones the
largest, the limb 3-4 mm. wide; fruit ovate-lanceolate, obscurely
1-nerved on one face, nerveless on the other, glabrous, pappose.

Valeriana plectritoides var. pallida Graebn. loc. cit.
Plant slender, many of the stems divergent; flower clusters
smaller.

Puno: Cuyocuyo, 3,800 meters (Weberbauer 928a, type). Ara-
ranca, 4,100-4,300 meters, Pennell 13438. Here perhaps belongs
also Pennell 13438a, which has a lax inflorescence.
Additional collecting must be done in southeastern Peru before
final disposition of this species and its close relatives, V. Herrerae,
V. sphaerocephala, and V. parvula, can be made. In V. oligodonta
the leaves are much larger and the inflorescence is more condensed
than in the type of V. plectritoides. The variety pallida is very
similar to Plectritis samolifolia in general appearance.
Valeriana pycnantha Gray, Proc. Amer. Acad. 5: 322. 1862.
A low, cespitose herb, glabrous throughout, the rootstock woody,
thickened; leaves rosulate, linear-spatulate, 2-3 cm. long, 3-5 mm.
wide, tapering gradually to a broad petiole, entire, carnose; stem
stout, 1-4 cm. long, bearing near -the middle 2 or 3 oblong, sessile,
verticillate, carnose leaves; head solitary, ovoid or subglobose, about
1.5 cm. in diameter; fruit narrowly ovate-oblong, the pappus 5-7-
rayed, brownish.

Valeriana quadrangularis HBK. Nov. Geh. & Sp. 3: 326. 1819.
Plant suffrutescent, essentially glabrous throughout, the stem
quadrangular, 30-40 cm. high; basal leaves ovate-oblong, 3-3.5 cm.

toward the base, petiolate, the cauline leaves similar, slightly
smaller and subsessile; inflorescence cymose-paniculate, rather laxly
dichotomous, the branches quadrangular; fruit linear-oblong, the
pappus about 14-rayed.
Peru: "Andes," Humboldt &Bonpland (type).
This is a doubtful species, as to both the systematic position it
should occupy and its place of occurrence. It very closely re-
sembles V. adscendens Turcz., an Ecuadorean species. If actually
from Peru, it was presumably collected in the northern part. It
was described as a shrub, and has been placed next to V. Grisiana
by Hock (Bot. Jahrb. 3: 49). The stem, however, is not densely
leafy as in other species of this group.
Valeriana radicata Graebn. Bot. Jahrb. 37: 436. 1906.
Plant erect, glabrous throughout, 25-50 cm. high, with a thick,

4. STANGEA Graebn.
Cespitose, acaulescent or subacaulescent, perennial herbs, the
roots fusiform and thickened at the apex, or stoloniferous; leaves
densely rosulate, fleshy; inflorescence sessile or terminating a short,
thick scape, densely flowered, flat-topped, hemispheric, or sub-
globose; bracts cuneate or cuneate-obovate; flowers polygamous
(always?); corolla limb 5-parted, the segments rounded; anthers
linear or linear-oblong, sessile or short-filamentose; fruit nerve-
less, pappose.
The present treatment of this genus is derived almost wholly
from Graebner's account. I have seen none of the specimens which
he cites, though photographs of all but one of the type specimens
are at hand. Further collecting will perhaps show that the lines of
differentiation between some of the species are too fine.
Plant densely cespitose, without stolons.
Leaves oblong or elliptic-oblong, acute or subobtuse, sessile.
