RUBIACEAE. Coffee Family
By Paul C. Standley

Trees, shrubs, or herbs with stipules; leaves opposite or verticillate,
entire or rarely pinnatifid; flowers small or large and showy, perfect
or rarely unisexual, usually regular; calyx tube adnate to the ovary
(hypanthium), the limb of the calyx usually dentate or lobate, one
or more of the lobes occasionally enlarged and foliaceous; corolla
gamopetalous, variable in form; stamens as many as the corolla
lobes, inserted commonly in the tube or throat of the corolla, the
anthers 2-celled; ovary 1-10-celled, inferior; fruit 1-10-celled, usually
baccate, drupaceous, or capsular; seeds 1 to many, small or large,
often winged.

The family is represented generously in most tropical regions,
and it is one of the largest of the Peruvian flora. Most of the Peru-
vian plants of the family are confined to the eastern slopes of the
Andes. Those occurring in the temperate regions belong chiefly to
the genera Galium, Relbunium, and Arcytophyllum.

6. CINCHONA L.

Trees or shrubs, glabrous or variously pubescent; stipules large,

paniculate, with opposite branches, usually many-flowered; flowers
5-parted; calyx campanulate, dentate or lobate; corolla salverform,

villous within along the margins; stamens semi-exserted or included,
with short or elongate filaments, the anthers linear; capsule ovoid
or oblong to subcylindric, bisulcate, dehiscent from the base to apex,
many-seeded; seeds broadly winged.

The genus contains some of the most important drug plants of
the world, the source of quinine, the universal remedy for malaria.
In former years large amounts of cinchona bark were exported from
Peru as well as from other regions of the Andes, particularly Bolivia
and Ecuador. The gathering of the bark involved the destruction
of the trees, and the supply of wild trees was finally almost exter-
minated. The greater part of the quinine now used in medicine is
obtained from trees cultivated in the East Indies.

There is a vast literature relating to the taxonomy and economic
applications of the genus. Those interested particularly in medicinal
properties of the plants made intensive studies of them, describing
a great number of forms as species. Many forms of the trees were
distinguished by the men who collected the bark, and various races
that differ but slightly in characters of foliage and flowers seem to
vary greatly as to their quinine content. Because of the large number
of names concerned, the synonymy of the genus is exceedingly
involved. The differences between the supposed species are poorly
marked and imperfectly understood, or perhaps rather confused by
the excess of attention paid to the forms. It is, therefore, dis-
couraging to attempt to present a reasonable account of the species.

The following enumeration of the Cinchona species is far from
satisfactory, but it will perhaps permit a sufficiently fine segregation
of the species. The greater number of the names in the genus relate
to forms of C. officinalis and C. pubescens. The species vary greatly,

FLORA OF PERU 25

but even after the examination of a large amount of authentic
material of their segregates, it does not seem possible to recognize
more than a few true species in the genus. The writer believes that
the greater part of the names published under the genus pertain to
forms of scarcely or not at all more significance botanically than
horticultural varieties of common garden vegetables.

Because of the involved synonymy, it is by no means certain that
all the names listed below are correctly placed. The most of them,
however, are of little importance, and it matters little what disposal
is made of them.
Leaves hirsute, hispid, or hispidulous beneath, at least on the costa

and nerves, the hairs stiff and spreading.
Leaves firm-membranaceous or subcoriaceous, usually dull, hirsute

or hispidulous beneath over the whole surface.
Leaves glabrate on the upper surface, long-hirsute beneath.

C. Humboldtiana.
Leaves appressed-pilose or glabrate on the upper surface, densely

short-pilose beneath C. Delessertiana.

Leaves mostly thick-coriaceous, lustrous, hirsute or hispid chiefly

on the costa and nerves.

Corolla 6-12 mm. long; leaves comparatively thin and large.
Corolla 10-12 mm. long; leaves usually copiously pubescent

rarely obtuse, coriaceous, glabrate above, pubescent-tomentose
beneath; calyx teeth triangular-lanceolate, acute; capsule oblong-

Puno : Described from thickets on the summits of the mountains
between the valleys of the Province of Carabaya, especially near San
Juan del Oro. Formerly, at least, planted in Java as a source of
quinine.

Weddell did not describe the flowers of this species, and its
position is consequently uncertain. It may be only a form of
C. officinalis, although in that species the leaves ordinarily are nearly
glabrous. Weddell states that the plant is called "cascarilla de las
lomas," and that it probably withstands a greater degree of cold
than any other member of the genus.

Schumann in the Flora Brasiliensis (6, pt. 6: 141. pi. 97} describes
and illustrates C. carabayensis, but since the writer has seen no
material of the species, even with his account of it there is difficulty
in placing the plant. If his description of the flowers is correct, the
species is close to C. pubescens, differing principally in its smaller
leaves.

In a genus in which very numerous species have been described,
based upon differences of slight importance, a group to which much
attention has been given because of its economic importance, it is
surprising to discover a form so conspicuously distinct from other
species of the genus as this. It is hard to understand why this
Mathews collection, made long ago, has not been named, but I can
find no mention of it in literature. The species is a well-marked one,
characterized by the very dense pubescence of short, spreading hairs
that covers all parts of the plant.

Weddell states that immediately after the bark is removed from
the tree it assumes a blood-red color, and that it is exceedingly
bitter. This species was formerly a more or less important source
of the drug cinchona.

This species was formerly an important source of cinchona bark
in the Andean region, and it was also the one first used in medicine.
It was first made known from the region of Loja, in southern Ecua-
dor. The species as treated here is a variable one, at least as regards
leaf form, but no clear lines can be drawn to separate the forms into
groups. It may well be, however, that with ample material available
for study, if it ever can be brought together, there may be found
some means of distinguishing several species in the material now
referred to C. officinalis.

11. LADENBERGIA Klotzsch

Shrubs or small trees, pubescent or almost glabrous; stipules
free or united, caducous; leaves opposite, petiolate, small or large,
often coriaceous; flowers large or medium-sized, disposed in terminal
panicles, these leafless and with opposite branches; calyx commonly
5-dentate or 5-lobate; corolla salverform, pilose, the lobes valvate,
short-papillose on the margins or over the inner surface; stamens
included, the anthers linear; capsule usually cylindric, dehiscent
from the apex, woody or coriaceous; seeds broadly winged.

The species of this genus, closely related to Cinchona, are almost
as difficult of discrimination as in the latter. Since they are of little
economic importance, less attention has been given to them by
botanists and pharmacists, and their synonymy is, therefore, far less
involved.

There is considerable doubt regarding the true generic position
of the plant here described, but it agrees better with Warscewiczia
than with any other genus with which I am familiar. In many
characters it is similar to W. Schwackei Schum., but in that the
flowers are glomerate and sessile, not pedicellate.

In aspect this tree is unlike the more common species of the
genus, since the bright-colored, enlarged calyx lobes are very few—
mostly at the base of the panicle — or altogether absent. Klug
reports the Huitoto name as "jayacoma" or "tayacona." He states
that the flowers are white.

"Machu sacha puca-quiro," "puca-quiru." Called "ararina,"
"asarauba," and "pau d'arara" in Brazil. Most of the collections
cited are in fruit or are sterile, and their determination is, therefore,
more or less uncertain.

In this, as in other species of the genus, the fine-grained wood
turns red as soon as cut and exposed to the air. The handsome colora-
tion, unfortunately, disappears after the wood has been exposed for
some time to the sunlight. Krukoff states that the wood is yellow
and very durable. He reports that the flowers have a strong and
agreeable odor of vanilla.

Although Hedyotis conferta and H. filiformis were maintained as
distinct species by Weddell in the Chloris Andina, the characters upon
which they were separated do not appear to be trustworthy. I have
seen a photograph of presumably authentic material of H. filiformis
from the Berlin herbarium, and it agrees with the plant described by
Weddell as H. conferta rather than the one which he describes and
illustrates as H. filiformis. Ruiz and Pavon give no distinguishing
characters in their descriptions of the two species, nor do their
illustrations give any clue for determining the differences between
what they assumed to be two species of the genus.

In the original publication of this species, the locality was given
erroneously as Colombia, but this was corrected later by Wernham
(see Kew Bull. 65. 1914). The plant has been confused with Isertia
hypoleuca Benth. of the northern coast of South America, which
seems not to be represented by Peruvian collections.

When the genus Creatantha was published by the writer, there
was available very ample material of a single collection. In this all
the corollas were uniformly funnelform-campanulate, the tube being
nearly or quite obsolete. The flowers appeared to be normal, and
there was no reason to doubt that a distinct new genus was repre-
sented. Soon after the publication of the genus, the writer received
from Berlin a collection of Rubiaceae in which was the Tessmann

FLORA OF PERU 79

collection cited above. In that there were found upon the same
branch corollas of the type just described and other tubular ones
such as are normal for the genus Isertia. It seems certain, therefore,
that the campanulate corollas are induced by some abnormal con-
dition, probably by insect action, although no proof of insect activity
is apparent in the specimens examined.

The type of H. angustifolia was collected in the mountains of
Peru (Huanuco?) by Haenke. I suspect that another synonym of
H. aggregata is Condalia sessilis R. & P. (Fl. 1: 54. 1798; Coccocyp-
selum sessile Pers. Syn. PI. 1: 132. 1805). Although described upon
the preceding page of Ruiz and Pavon's work, the descriptions of the
two plants are much alike. Certainly the plant can not be a species
of Coccocypselum.

as a distinct species by Wernham (Journ. Bot. 49: 213. 1911), but
it seems to differ only in having spherical rather than ellipsoid fruit,

Schumann compares the foliage to that of the pear, and the com-
parison is an apt one. According to Schomburgk, who collected the
original specimens in British Guiana, the wood is considered by the
Indians to be poisonous, and some of them had been poisoned by
using spits made from it for roasting meat over the fire. Recent
collectors describe the plant as a tree of 4-8 meters, with wide-
spreading branches and thick foliage, the flowers white and slightly
fragrant.

"Espuela casha," "espino," "clavo-caspi." The shrub is abun-

slimy pulp of repulsive appearance, which nevertheless is sometimes
eaten by people, although of scarcely pleasant flavor. It is much
sought by birds, which extract it from a hole punctured in one side

"Jagua," "vito," "yaku-huito," "vitu," "palo Colorado. Known
in Brazil by the names "jenipapa," "jenipabo," "jenipapo." The
wood is strong, resistant, and flexible. Ruiz and Pavon report
that it was employed in Peru for making various utensils, and it is
a favorite wood for construction purposes in many parts of tropical
America. The pulp of the fruit is edible, but not remarkably
palatable. Its dark juice leaves an indelible stain upon every
object that it touches. It formerly was much used by the aborigines
for painting their bodies, yielding a dark blue or black color, and
doubtless it still is employed in the same manner by the uncivilized
Indians of the forests along the eastern slopes of the Andes.

So far as I am able to determine, neither Genipa oblongifolia nor
G. excelsa differ in any respect from the typical form of G. americana.
GenipaCaruto, of northern South America, with soft-pubescent leaves,
is perhaps best regarded as a distinct species, although it differs little
from G. americana except in its copious pubescence.

Huanuco: Type from Muiia, Ruiz & Pavdn.

I have seen a photograph (ex hb. Berol.) of presumably type
material of this species, and so far as may be judged from the
photograph, the plant is not specifically distinct from G. hirsuta.
The original description and illustration agree well with material
of G. hirsuta, except in the number of cells in the fruit and ovary,
and that may well be a variable character.

Tournefortiopsis major was based upon Poeppig 1300, from
Peru or Brazil, but doubtless from Peru, since the plant is a mountain
species, which scarcely would be expected anywhere along the
Brazilian Amazon. Cordia Poeppigii (of which I have seen a frag-

G. pichisensis was described as new before the writer had seen
authentic material of G. ochreata, with access only to its descrip-

nation of a photograph and a fragment of an authentic specimen of

Coffee is grown extensively in Peru at suitable elevations. As
in all regions where the plant is grown, it sometimes escapes to
thickets and forests and tends to establish itself. A coffee plantation
in full flower is a beautiful sight. All the bushes come into blossom
at once, but unfortunately the flowers last only two or three days.

"Uchu sanango." The species is easy of recognition because of
the large and brightly colored bracts, which are reported variously
as blue, pink, or white. Some of the specimens have been determined
as Faramea Schwackei Schum. & Krause, a species described from
Amazonian Brazil, which does not seem to differ from F. anisocalyx.

Of the plant Huber (Bol. Mus. Paraense 4: 615. 1906) writes as
follows: "This shrub is one of the most beautiful ornaments of the
Ucayali region because of its bracts, which are of a pure sky blue
and literally cover the plants when in flower. Crossing the forest
west of Sarayacu I was deceived several times by the numerous
shrubs of this species, thinking that I was seeing the sky through
the trees."

Faramea axillaris Standl. Field Mus. Bot. 8: 178. 1930.

"Charichuela," "situlli caspi." Some of the collections cited
have been referred erroneously toF. candelabrum Standl., a Bolivian
species. Others have been determined as F. amazonica Muell. Arg.,
a species that I do not believe is distinct from F. glandulosa. The
ample material at hand is somewhat variable, however, and it is
possible that it represents more than a single species, although no
lines of segregation are now apparent.

When this plant was first described by the writer, only flowering
specimens were available for study, and it was impossible to do better
than refer it to Retiniphyllum, a group with which actually it has
no affinities. The fruiting specimens collected by Krukoff show
that it is referable without question to the tribe Psychotrieae. The
fruit is strikingly like that of coffee in general appearance, but the
plant's relationship is with the genus Psychotria. That is so vast a
group, with such a wide range of characters, that it is difficult to
assign distinctive characters to Stachyococcus. However, in its
general appearance Stachyococcus bears no close resemblance to any
species of Psychotria with which I am familiar, the form of the
inflorescence alone being sufficient to distinguish it, and I suspect
that the differences between the two genera are important ones.

69. CEPHAELIS Sw.

Shrubs or small trees, sometimes herbs; stipules free or connate,
usually persistent; leaves opposite; flowers capitate, subtended by
an involucre of usually sessile, free or connate, often colored bracts,
the heads terminal or axillary, simple or branched; calyx short or
elongate, 4-7-dentate, persistent; corolla funnelform or salverform,
the tube straight, commonly elongate, the throat villous or naked,
the lobes 4-5, valvate in bud; stamens inserted in the throat of the
corolla, the filaments usually short, the linear anthers included or
exserted; ovary normally 2-celled; fruit drupaceous, containing 2
hard, smooth or costate nutlets, these usually longitudinally sulcate
on the inner face.

The genus is scarcely a natural one, there being no sharp line of
demarcation between it and Psychotria. For the most part, however,
it is possible to refer a species readily to one or the other group, and
since both genera are large ones, it seems desirable to recognize
Cephaelis as distinct, merely as a matter of convenience.

Casual reading of the descriptions of Coffea umbellata R. & P.

The key presented above is, in large part, an altogether unsatis-

material, which represents all the species listed. All or most of the
species are, I believe, valid ones, but some are known only in fruit
and others only in flower, consequently it is impossible to compare
their corresponding characters.

The Berlin specimen of which I have seen a photograph is in
rather poor condition, with fruit only. It is not at all certain from
examination that the plant is a Rudgea. At Berlin it has been
placed in Faramea, but the fruit appears to be decidedly longer

resemble a Coussarea.

Huanuco: Described from Pati and Macora, Ruiz & Pavon

The specimen of which I have seen a photograph is in fruit only,
and it is not possible to determine satisfactorily the generic position
of the plant. It is doubtful whether it really is a species of Rudgea.
In the Berlin herbarium it appears to have been referred to Faramea,
but the form of the fruit excludes it from that genus.

72. PSYCHOTRIA L.

Shrubs or small trees, rarely small and only suffrutescent plants;
stipules persistent, and then commonly bilobate, or caducous, and
then usually entire; leaves opposite; inflorescence chiefly terminal,
but in a few species axillary, variable in form, but rather rarely
head-like and then seldom conspicuously involucrate, never with
a showy involucre of partially united bracts, the flowers generally
small, inconspicuous, and white or yellowish; calyx lobes short or
elongate, often obsolete, more or less united; corolla short or elon-
gate, with straight tube, often barbate in the throat, the lobes
valvate; stamens inserted in the corolla tube, included or exserted;
ovary mostly 2-celled but rarely 5-celled (subgenus Nonatelia);
fruit baccate, containing 2 or 5 nutlets.

The genus is the largest and most complicated group of American
Rubiaceae, but the species, although so numerous and often much
alike in general appearance, are separated by constant and prac-
tical characters, except in a few groups in which probably too many
species have been described. The species certainly are much easier
of recognition than those of the genus Palicourea. The key given
below, except for the two primary divisions, is not at all a natural
one, but in view of the fact that so many of the species are known
only in flower or else only in fruit, it has seemed preferable to attempt
to key the species by recognizable even if not systematically im-
portant characters.

Psychotria is only vaguely separable from Palicourea and Cephae-
lis (and not too distinct from Rudgea). It is doubtless more logical
to refer Cephaelis, Palicourea, and Psychotria all to Psychotria, as
was done by Mueller in the Flora Brasiliensis, but all three groups
are large ones, and it is decidedly convenient to maintain all of
them. Although a small proportion of the plants concerned are of

172 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XIII

uncertain generic position, ninety per cent of them can be referred
at a glance definitely to a genus, at least by one who has some
general knowledge of the group.

Mueller, however, maintained as distinct the genus Mapouria,
here merged in Psychotria. The two genera are separable only on
fruit characters, and the fruit of many species still is unknown.
Even if it were known for all, I do not believe that Mapouria is
an important group or worthy of generic rank. Although one group
— the species with deciduous stipules — can be recognized by gross
aspect, many others — those with persistent stipules— evidently are
closely related to typical Psychotrias.

The section or subgenus Nonatelia, containing species with
5-celled fruit, does seem to be worthy of generic rank, but it con-
tains only half a dozen species, and would therefore have no prac-
tical value in facilitating determination, especially since it is not
easy in flowering specimens to determine the number of cells. A
larger number of Palicoureas also have 5-celled fruit, and would be
equally worthy of generic rank, but they are quite different in general
appearance from the Psychotrias having similar fruit.

Bremekamp, in his excellent account of the Rubiaceae in Pulle's
Flora of Surinam (1934) has proposed still further segregates from
Psychotria, recognizing, besides Cephaelis and Mapouria, Notopleura,
Ronabea, Gamotopea, Petagomoa, and Nonatelia, all of which are
represented in Peru. While such a division of the genus may be
found altogether satisfactory within a limited area, it can scarcely
accommodate all the South American species of Psychotria, at least
with the material now available for their study. Such a division,
if applied uniformly to the whole genus, would involve the segrega-
tion of still further genera, a treatment that ultimately may be found
most consistent.

182 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XIII

A shrub or tree 3-12 meters high, the branchlets tomentulose or
glabrate; stipules 6-7 mm. long, ovate, short-acuminate, sparsely
pilose outside; leaves petiolate, the blades herbaceous, obovate-
oblong or obovate-spatulate, 24-27 cm. long, 12 cm. wide or less,
glabrous above, short-pilose beneath especially along the costa,
short-acuminate, rather abruptly narrowed and attenuate to the
petiole, the lowest nerves ascending at a very acute angle; panicle
pedunculate, lax, 20 cm. long and broad, the lowest branches divar-
icate or subrecurved; calyx dentate; corolla bright yellow, 3 mm.
long, the lobes slightly shorter than the tube. Neg. 469.

Type from Monte Mo on the upper Rio Acre in Brazil, Vie
9852 (photo, and fragm. seen, ex hb. Berol.). The locality is near the
Peruvian border, and the species, therefore, is to be expected con-
fidently in Peru.

"Cucha caspi," "trompetero caspi." If I have interpreted
P. capitata correctly, as I think is the case, P. inundata is a clear
synonym. It appears likewise that P. chlorotica Muell. Arg., a name
under which some of the Peruvian material has been distributed,
should be reduced to synonymy under P. capitata. The characters
used by Mueller in separating P. chlorotica and P. inundata are
certainly of little or no importance.

that is, provided along the costa with small, sack-like structures that

The Spruce collection was referred by the writer to Psychotria
lassula Standl., but there seems to be no reason for segregating it
from the Krause species, and P. lassula, as pertains to the type speci-
men, likewise may not be separable. Both species belong to a small
group of epiphytic plants, whose forms are closely related, and it
remains to be seen how many of the proposed species can be main-
tained when ample material is available for consideration.

dilated on one side at the base; fruit drupaceous, 2-5-celled.

The genus is close to Psychotria, and is not distinguished from it
by any constant character, nevertheless Palicourea is a convenient
group, and the species usually may be distinguished by their general
aspect from all the Psychotrias. Some of the species listed below
may be better referable to Psychotria than to Palicourea, but their
proper status can not be settled satisfactorily without more ample
material than is now available. The species are not so well differ-
entiated as those of Psychotria usually are, and the following key
will not be found altogether satisfactory for their separation.

outer surface and often tufted. Leaves opposite, often very
large.

Psychotria caerulea R. & P. Fl. 2: 62. pi. 213, f. b. 1799.

A glabrous shrub; stipules ovate, entire; leaves opposite, short-
petiolate, lanceolate, long-acuminate, acute at the base, large;
panicles sessile, open, many-flowered, the branches spreading or
ascending, the bracts ovate; flowers sessile in dense clusters; calyx

Junin: The species was based upon a drawing of a plant growing
at Vitoc, sent by Tafalla to Ruiz and Pavon.

The species is not included in the key. If the original descrip-
tion and illustration are correct in ascribing entire stipules to the
plant, it is not a species of Palicourea, and the illustration suggests a
Psychotria. Since probably no specimen of the species was preserved,
it is likely to remain unplaced.

FLORA OF PERU 227

Stipules triangular, acute; leaves petiolate, oval, about 21 cm.
long and 10.5 cm. wide, rounded and shortly produced at the apex,
abruptly contracted at the base, thin, pilose beneath, especially
along the nerves, with about 11 pairs of nerves, these conspicuous,
the lowers ones divergent at almost a right angle, the upper at an
acute angle, the veins prominent and reticulate; panicle pedunculate,
thyrsoid-pyramidal, 14 cm. long, the rachis very stout, the branches
ascending or spreading, the flowers pedicellate; bracts deciduous;
corolla purplish, glabrous, 8 mm. long.

Type from "Peruviae montanis Oronoccensibus" (probably
Huanuco), collected by Haenke.

The only material I have seen is a specimen in the herbarium of
the Missouri Botanical Garden, which apparently is an authentic
one — from the Bernhardi Herbarium. The plant represented is
probably only a somewhat abnormal form of P. amethystina, and
therefore was collected in the mountains of Peru. The leaves —
there is a single one with the specimen mentioned — appear to be
somewhat abnormal. In Palicourea the leaves nearly always are
acute or acuminate.

A glabrous shrub; stipules short, bifid, the lobes ovate, obtuse;

In spite of the description of the plant as glabrous, it seems
probable, after examination of the plate, that this is a synonym of
Palicourea macrobotrys. Since probably no specimen of the species
is preserved, it will be difficult to place it satisfactorily. It is not

This species, which is common in Venezuela, was based by
Wernham upon three collections from that country. With these he
cited a specimen collected by Pearce at "Muna," believing that it
was Venezuelan. The Peruvian collection should be examined
further, in order to determine whether it really is referable to P.
perquadrangularis, a reference that is probably incorrect.

Huanuco, Chancay, and Lima. If it was found by those early col-
lectors at so many stations, it is strange that it has not been redis-
covered in recent years.

collected at Tarma by Ruiz and Pavon. Schumann considered this
and R. ovale as probably identical, but in the latter the leaves are
oval, rather than linear, as described for Galium mucronatum. I
have seen no material of the Ruiz and Pavon plant, and their descrip-
tion is far from satisfactory, hence it may be that the name refers to
some species other than Relbunium ciliatum.

FLORA OF PERU 261

I have seen type material of the three species referred here,
and fail to find any important differences between them, if any at all.
It is probable that all three names should be reduced further to
synonymy under G. canescens.

Galium limense Standl. Field Mus. Bot. 4: 298. 1929.

A diffuse, procumbent perennial, the stems sparsely uncinulate;
leaves in 4's, oblong-ovate, 5-8 mm. long, acuminate, obtuse at the
base, 3-nerved, scaberulous above; cymes 3-flowered, axillary and
terminal ; corolla green ; fruit dry, densely uncinate-hispidulous.

Lima: Canta, 2,800 meters, open, rocky slope, Pennell 14351,
type.

This, too, probably is a mere form of G. canescens.

Galium pumilio Standl. Field Mus. Bot. 4: 298. 1929.

A diminutive, densely matted, compact herb, the stems 1-4 cm.
long, glabrous; leaves in 4's or 6's, usually longer than the internodes,
oblong or ovate, 1.5-2.5 mm. long, obtuse or acutish, glabrous,
ciliate; flowers axillary, solitary, on pedicels 4-8 mm. long; fruit
fleshy, glabrous.

Junin: Cerro de Pasco, grassy limestone slope, 4,200 meters,
Macbride 3070, type.

Doubtful genus

Riqueuria avenia R. & P. Fl. 1: 70. 1798. Riqueuria R. & P.
Prodr. 18. 1794.

A procumbent shrub, the stem branched, the branches naked
below; leaves opposite, petiolate, the blades oblong, entire, glabrous,
not nerved; racemes short, terminal; pedicels 3-flowered; corolla
yellow, fleshy. — Growing in the forests of Chinchao and Cochero,
especially near Casapi and Casapillo.

The genus has been referred generally to the Rubiaceae, but its
proper position has not been suggested. The group is altogether
doubtful.
