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). VALERIANACEAE. Valerian Family By E. P. Killip, U. S. National Museum References: Dufresne, Hist. Nat. Med. Valerian. 1811; Weddell, Chlor. And. 2: 17-34. 1857; Hock, Bot. Jahrb. 3: 1-74. 1882; Graeb- ner, op. cit. 37: 436-451, 464^80. 1906; Briquet, Ann. Conserv. 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. Corolla 5-parted; leaves up to 2 mm. long A. Aschersonianum. Corolla 3-parted; leaves 3-5 mm. long A. imbricatum. FLORA OF PERU 289 Aretiastrum Aschersonianum Graebn. Bot. Jahrb. 37: 448. 1906.

Piura: Huancabamba, 3,200 meters, Weberbauer 6088 (type). This species surely belongs to Aretiastrum, though the corolla has only 3 lobes, whereas in the four other known species it is 4- or 5-lobed. 2. ASTREPHIA Dufr.

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, the pappus 6-rayed, pilose. Amazonas: At 2,700-3,300 meters, Williams 7580. Chachapoyas, 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.

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 (?).

Valeriana plectritoides var. pallida Graebn. loc. cit. Plant slender, many of the stems divergent; flower clusters smaller. 310 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XIII 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.

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.

Gourd Family To tell the story of the gourd or calabaza would be nearly to trace the story of mankind from the time of its written record, for the first dish and the first bottle may well have been fashioned from a fruit of some form of the vine botanists have named La- genaria siceraria, or others (in Peru) "poro," "matha," or "mati," the last two in the Quichua language. Records in literature exist from the ninth century, and there is a picture that dates from 1484. In Peru itself the fruit and seeds have been found in ancient graves of the Incas (Rochebrune, Act. Soc. Linn. Bordeaux 33: 347. 1879; Costantin & Bois, Rev. Ge"ne>. Bot. 22: 259. 1910 ; Safford, Smithson. Rept. 1916: 409. 1917) ; nevertheless the origin of the species remains obscure— cf. Harms, Pflanzenreich IV. 275, pt. 2: 206-208. 1924, who has brought together a remarkable fund of data on the gourd in all its phases. Besides the usual use in Peru of gourds for vessels of all sorts, I found a small variety commonly carried by coca chewers to con- tain the supplementary lime. Such gourds have been found with 322 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XIII Peruvian mummies (Safford), and one of the modern examples brought back by a Field Museum expedition is to be seen at that institution. A large gourd seemed regularly to serve, from the coast to the interior, as the container for the popular beverage chicha. Besides the gourd, the well known cultivated members of the family, such as Cucurbita moschata Duch., squash, and C. Pepo L., the "zapallo" or "pasin huara" (Tessmann) and "calabazas" — one of these may be the "calabaza vinatera" of Ruiz and Pavon, "which has a very good taste cooked"; Cucumis Melo L., "melon," and C. sativus L., cucumber, are, in my experience, not generally known or appreciated. Herrera found the squash adventive in the Valle del Urubamba, Tessmann the zapallo in Loreto. Spruce, it may be remarked, noted the native names "boga-boga" and "caiwa" for two Amazonian species not yet placed. The following compilation, as the references indicate, is largely copied from the works of Cogniaux and Harms. It is with pleasure that I acknowledge the latter's willingness to prepare an account of the family for this work, and I regret that his duties as editor of Pflanzenfamilien finally did not permit him to do so. Other con- tributions to the part being ready, I had to attempt it myself, but, as a matter of fact, keys had been tentatively made for the collections in Dahlem, thanks to Professor Harms, who named all my own material and gave me access to all of that in his care. These facts are mentioned to explain any new interpretations. As the genera are at best difficult to distinguish, three keys to them have been provided: one, completely artificial, leads, with a little experience, to most, at least, of the Peruvian species; another is according to Engler; and a third is an adaptation of that with Cogniaux's, for it has seemed to me that to regard the nature of the anthers, in view of their variation, as indicating the natural division of the family may not be correct, and one more nearly approaches, at least as regards the Peruvian groups, a lineal arrange- ment that appears natural by employing the position of the ovules as basic. The student should be cautioned that filaments when short sometimes are not readily obvious; also, that occasionally stamens may be lightly coalescent in an early stage when really "free." In general, for simplicity, I have followed the earlier use of the term "calyx" (with sepals) to designate the receptacle, which term even modern authors have not always employed consistently.

FLORA OF PERU 341 Lianas or herbaceous, perennial vines with simple or bifid tendrils, entire, lobed, or 3-5-foliolate leaves, and small or conspicuous flowers, these usually dioecious, the staminate variously borne, most often racemosely, toward the summit of a long peduncle. Calyx tube elongate, green, half green, or colored, the sepals, as in other genera, developed to greater or less degree. Corolla about rotate, the more or less spreading and broad petals longer than the sepals (Sect. Euanguria Schlecht.) or rarely subequal, or erect or suberect, relatively narrow, and much shorter than the sepals (Sect. Gurania Schlecht.). Stamens 2, sessile, dorsifixed, free or coherent. Anther cells straight, curved or replicate below, the connective often produced. Pistillate flowers solitary or few. Staminodia none or 2. Ovules many, horizontal. — See also the segregate Dieudonnaea. To avoid awkwardness in making new combinations in incidental references, some species are listed as G. (Gurania). It seems obvious that the division of Anguria into three genera is arbitrary. Recently described species show further the relative development of the characters. It is interesting to note the vari- ation in anther cells within this natural genus, a variation accepted by Cogniaux himself. For simplicity the receptacle has been termed here the calyx tube, following many writers. Generally colored in the section Gurania, at least one species therein has the calyx tube green in the lower half.

A tall, smooth, dark green vine with ample, roundish, 3-lobed, cordate leaves, the lobes acute or acuminate, undulate, denticulate; staminate peduncle, 2-4 cm. long; calyx ashy-tomentulose, the tube 6-8 mm. long, the lobes 9-12 mm. long, 5-8 mm. wide; corolla almost fleshy, tomentulose, the lobes 5-nerved without, 2 cm. long, 10-12 mm. wide; filaments glabrous, 3-5 mm. long, half as long as the extremely flexuous anthers; fruit generally cylindric or some- times oblong-ovoid, to 50 cm. long or longer, often much shorter; seeds about 1 cm. long. — Later authorities cite the Hasskarl name "evodicarpa." One of the plants growing in Peru first to be commented upon, for it was described in 1658 by Piso, who at that time found it much in favor because of its fragrant fruits that were used, as at FLORA OF PERU 363 present, to scent linen and clothing; and Ruiz and Pavon remarked its "delightful fragrance," for which it was much used to adorn altars. It happens that it was the first plant collected by me, for it was cultivated in the patio of the well known physician and enthusiastic botanist of Lima, Dr. A. Aspiazu, whose name may well be mentioned, for he subsequently led me to many other inter- esting plants. A model of this specimen may be seen in the exhibits of Field Museum. It is not certain that the species is known in Peru in a native state. Loreto: Puerto Arturo, 200 meters, Williams 5223. San Isidro, Tessmann 4968, 4985. Yarina-cocha, Tessmann 5411. (All det.

Gen. 1: 255. 1891, employs the name Arkezostis Raf . ; his names are not cited here, this reference sufficing. The species are separated with difficulty. The character of the glands used by Cogniaux as important is apparently to be taken with caution, since authoritatively named material of C. citrullifolia sometimes is slightly glandular; therefore this character has been used as a secondary one in the following key. Leaves glabrous beneath or essentially so. Leaves 3-foliolate C. amazonica. Leaves simple. Calyx tube about 2 cm. long; leaves eglandular. .C. macrocalyx.

CALYCERACEAE This small family, with flowers aggregate into heads and more or less mixed with bracts or paleae in the manner of the Compositae, from which, however, it differs in having the ovule suspended from the tip of the cell, fruits or achenes topped by the calyx, etc., is represented in Peru apparently by only four species, although there are a number in Chile and Argentina, some of them extending into Bolivia. Perhaps the best account of the family as yet is by Miers, Contr. Bot. 2: 1 et seq., who, however, divides it into several more genera than the four ordinarily recognized today: Acicarpha, Boopis, Moschopsis, and Calycera. As all the genera may be found eventually in Peru, it may be remarked that Boopis resembles Calycera but that in Boopis the fruits are all alike, the calyx not changing. The well known teasel, Dipsacus fullonum L., with rigid, ovoid heads, and Scabiosa atropurpurea L., "ambarina," often cultivated in flower gardens, with finely divided leaves and soft heads of pale purple or white flowers, may both occur occasionally as escapes. They are placed in a family separated from the Calyceraceae because the filaments are not united at the base into a ring, the Dipsacaceae. Outer achenes concrete, bearing spines at the apex 1. Acicarpha. Outer achenes free. Achenes, at least the outer ones, armed with spines . . 2. Calycera. Achenes unarmed 3. Moschopsis. 1. ACICARPHA Juss. Annual or perennial herbs with spatulate or obovate leaves. Involucral bracts united below with the receptacle, this sometimes provided with small palae. Central flowers sterile, the outer 2 or 3 series maturing more or less united achenes which are somewhat sunken in the conic or elongate receptacle, and crowned with the definitely lengthened, more or less spinescent calyx teeth. — Robert Brown renamed the genus Acicarpa as more appropriate, which action was followed by Miers. Plants procumbent, the leaves entire A. procumbens. Plants erect, the leaves toothed or laciniate A. tribuloides. 490 FIELD MUSEUM OF NATURAL HISTORY — BOTANY, VOL. XIII Acicarpha procumbens Less. Linnaea 6: 527. 1831. Glabrous, usually with many much branched stems; leaves narrowly spatulate, attenuately petiolate, 2.5-4 cm. long, 4-8 mm. wide, glaucous, 3-nerved; peduncles opposite the leaves, about 2 cm. long, the solitary head 1 cm. thick, the 5-6 involucral leaves about 4 mm. long; achenes corniculate-spinose, 5-winged, the spines about 1 mm. long. — Acicarpa spathulata R.
