By Elmer D. Merrill. The material upon which the present paper is based has been collected during the past year and is deposited in the herbarium of the Bureau of Government Laboratories, Manila. The numbers cited, unless otherwise stated, are those of the author's distribution. Duplicates have been distributed to the United States National Herbarium, Washington; the K. K. Botanische Garten, Berlin; the Koyal Gardens, Kew ; the New York Botanical Gardens, and other institutions. As yet there has been little opportunity to critically study the many interesting species in the collection, and the present paper records only a few notes on some of the most characteristic species. ANACARDIAOEiE. Semecarpus gigantifolia F. Villar, Nov. App. Fl. Filip. August. Add. et Corrig. 350. 1883; Vidal, Sinopsis, Atlas, XXJI. t. liG. f. A. 1883. This most distinct and interesting species is not noted in Index Kewensis, and is represented in our herbarium by No. 2491 , Lamao River, Mount Mari- veles, Province of Bataan, Luzon, June 11, 1903, also by No. 511 (Aliern), Tetuan, Province of Zamboanga. Mindanao, 1901. The specimens observed at Lamao River were trees 10 m. high and about 20 cm. in diameter, unbranched or with very few (three or four) ascending branches, the leaves, which exceed 1 m. in length, being crowded at the apices of the branches, giving the plant a striking, almost palm-like appearance. The fruit is borne in great abundance on panicles 10 to 20 cm. long, the entire length of the trunk. The hypocarp is very fleshy, deep purple when ripe, 3 to 4 cm. long, and edible, although somewhat puckery. Known by the Tngalogs as Tocud langit and by the Viscayans as Manalu. BOIUiAGINACEYE.

This is evidently a distinct species, being represented in our herbarium by No. 153, a small tree, 8 to 10 m. high, with pale purple flowers, collected in the mountains between Bagabag and Quiangan, Province of Nueva Vis- caya, Luzon, June 7, 1902, also No. 2291, Tanay, Province of Rizal, Luzon, Ma v , 1 902 . Taga 1 og, Ma lasam bong. CONIFEREzU. Pin us insularis Endl., and P. mercusii Jungli. and De Vriese. Species of the genus Pinus are found in the mountains of northern Luzon, in the Province of Nueva Ecija, Nueva Viscaya, Zambales, Benguet, and Lepanto-Bontoc, the most widely distributed species being Pinus insularis EndL, which is apparently very closely related to J'inua khasya Royle, from Burma. Specimens from Benguet have been identified as the latter species. Pinus mercusii Jungh. and De Vriese, has been found only in the Province of Zambales, and from material recently received, distributed as No. 2116, it appears doubtful if the Philippine specimens so referred, are really this species. Pinus mercusii Jungh. and De Vriese, lias only two leaves in a fascicle, while Pinus insularis EndL, has three leaves in a fascicle. In No. 2110, on the same branch about one-half of the fascicles contain two leaves and the other half contain three leaves. Other specimens. No. 1158 (Mer- rill) and No. 829 (Ahern) from Zambales invariably contain two leaves in a fascicle, while the specimens Nos. 1161, 1162, 1163, 1164, 1165 (Merrill), Nos. 830, 852 (Ahern), and Nos. 121, 122, 123, 124 (Topping), from Ben- guet, always contain three leaves in a fascicle. It is very difficult to sepa- rate Pinus insularis Endl. and Pinus mercusii dimgh. and De Vriese on any characters other than the number of leaves in a fascicle, and it is suggested that the Philippine material identified as Pinus mercusii Jungh. and De Vriese, may be only a form of Pinus insularis Endl. The specimens of Pinus in our herbarium are extremely variable, and may represent one variable species, or several closely related ones. The Igorrotes in Benguet have distinctive names for different forms of Pinus insularis Endl., but their names are, 1 believe, based upon the amount of resin in the tree, rather than upon any vegetative or floral characters. The native names for Pinus are: Taga log, Salong or Salcng ; Zambales, Tapulao ; llocano, Parua; Igorrote, A l-al. GRAMINE/B. Erkmoctiloa leersiodes (Munro) Hack, in DC. Prodr. 6: 264. 1889. (Ischacmum leersiodes Munro, Proc. Amer. Acad. 4: 363. 1864-65.) This species, previously known only from southern China and California, introduced in the latter place, was found growing abundantly in open grass lands near Echague, Province of Tsabcla, Luzon, June 11, 1902, (lis- tributed as No. 138. No species of this genus has been previously reported from the Philippines. Oryza gkanulata Nees et Arn. in Wall. Cat. No. 8634. 1828. {(). fili- formis Herb.; 0. meyeriana Zoll. et Mor.) This species was found sparingly along trails in dense damp forests in the hill country near Quiangan, Province of Nueva Vizcaya, Luzon, June 6, 1902, No. 116. This number differs from Oryza aranularis, as described, in its somewhat larger spikelets, but is manifestly this species, which is distributed from the Himalayan region to Malabar, Madura, Java, and Celebes. Polytkias praemorsa ( Noes ) Hack, in DC. Monog. Phanerog. 6: 189. 1889. (Pollinia praemorsa Nees.) This species, previously known only from Java, was found growing abundantly in dry, open, waste places, Manila, December 0, 1902, distrib- uted as No. 380. It is quite evident that this species is not a native of the Philippine Islands, but has been introduced from Java or from Singa- pore; it is very common at Singapore and may be also a native of that region or may have been introduced from Java. It is one of the most common and widely distributed species of the (jramincw in the Island of Java. LEGUMINOSEiE. Pterocarpus blancoi Merrill, sp. nov. {P. santalinus Blanco, FI. Filip. ed. 1, 561. 1837, non Linn, f.) This species is very different from Pterocarpus santalinus Linn, f., being distinguished by its acuminate, not obtuse, leaflets and much larger pods. The wing of the pod is much broader in this species than in Pterocarpus indicus Willd., while P. santalinus Linn, f., is described as having a pod with a narrower wing than that species. It is distinguished from P. indi- cus by its longer, acuminate leaves and larger pods. According to Hooker P. santalinus Linn, f., does not extend to the Malayan region. This species is known to the natives as Narra or Asana, both names also being applied to Pterocarpus indicus and P. echinatus, but /'. blancoi has also a distinctive name Apalit, probably on account of its odorous wood. It is believed that the wood of the other two species noted above is without this distinctive odor. This species is represented in the herbarium by No. 2881, Tarlac, Prov- ince of Tarlac, Luzon, July. 1903. Mezonei'ri/m hi r.iUM Merrill, sp. nov. A robust prickly climber 6 to 10 m. long, with large obtuse, glabrous leaflets and oblong long-pedicel led red pods. Leaf-rachis 5 to 6 dm. long, glabrous, with stout retrorse prickles on the under side; pinnae 6, 1dm. long, 6-jugate; leaflets firm ovate or obovate, glabrous, obtuse or emar- ginate at the apex, the base obtuse, inequalateral, 5 to cm. long, 2.5 to 3 cm. wide, the nerves not prominent, freely anastomosing; petiolules 3 mm. long. Racemes as long as the leaves, pubescent. Flowers unknown. s Pods thin, glabrous, 4 to 5 seeded, 15 cm. long, 4 to 5.5 cm. wide including the wing, which is 1 cm. in width; pedicels 2.5 to 3 cm. long. Type specimen No. 805, growing in thickets, Point Seperation, Paragua, February 18, 1903. This species is probably most closely related to Mczoncurum sumatranum Miq., but may possibly not belong to the section Tubicalyoc, it being im- possible to determine this point with the material at hand. It differs from that species in its smaller number of pinnoe and leaflets, smaller leaflets, longer pods and long pedicels. MELIACEiE. Sandoricum vidalii Merrill, sp. nov. (8. bornccnse Vidal, Cat. PI. Prov. Manila; F. Vill. Nov. App. 43, non Miquel.) A tree reaching a height of 20 m., with glabrous ovate, acute or slightly acuminate leaves, reflexed petals and glabrous ovaries. Branches glabrous, gray. Leaves 1.5 to 2.5 dm. long, the petioles 5 to 7 cm. long; leaflets ovate, the base acute, 6 to 14 cm. long. 4 to 9 cm. wide, the nerves 8 to 10 pairs, petiolules of the lateral leaflets 5 mm. long, those of the terminal leaflet 3 cm. long. Panicles glabrous, many flowered, 5 to 6 cm. long. Flowers 6 to 7 mm. long, their pedicels about the same length. Calyx glabrous, cup shaped, with 5 obscure, broad, rounded teeth. Petals to 7 mm. long, 2 mm. wide, glabrous, obtuse, recurved in anthesis. Staminal tube cylin- drical, ridged, not ventricose, 5 to 6 mm. long, with 10 obscure teeth. Ovary glabrous. Style 3 to 4 mm. long. Stigmas 5, distinct, erect, 1 mm. long. Fruit (immature), globose, somewhat flattened. 2.5 cm. in diameter, mi- nutely and densely velvety-pubescent. Type specimen No. 1824, P>osoboso, Province of Rizal, Luzon, April, 1903 (flower). The following specimens are also referred here. No. 2279, Tanay, same province, May, 1903 (fruit) ; No. 2060, Guinayangan. Province of Tayabas, Luzon, April, 1903 (fruit) ; No. 1923, from Pagbilao, Province of Tayabas (flower), is also doubtfully referred here, differing from the type in some minor characters. This species is evidently most closely related to Sandoricum maingayi Uicrn, from Malacca, but is distinct from that species. It is undoubtedly the species erroneously identified by Vidal as Sandoricum bornccnse Miq. This tree grows in dry hill forests, reaching a height of 20 meters, and a diameter of 00 cm., the sap wood is white or pink and the heart wood is of a violet color, it being used by the natives in the construction of houses. The watery sap has a faint odor, similar to that of Sandoricum indicum. Tagalog Malasaniol, literally "false santol." in distinction from the true santol, Sandoricum indicum L. MORACEyE. Ficus LizoNENSis Merrill, sp. nov. (Eusyce.). A small tree with firm ovate, somewhat pubescent leaves and long- peduncled, globose, densely pubescent receptacles. Leaves 7 to 10 cm. \) long, 3 to 4 cm. wide, ovate or ovate-lanceolate, apex acute, or obtuse, base acute, margins entire, rather strongly revolute, glaucous and harsh above, with few scattered, striate hairs, beneath usually densely brown- punctate, nerves rather prominent, 4 to (> pairs, which with reticulations are rather densely pubescent; petioles 2 to 2.5 cm. long, densely pubescent; stipules lanceolate, acute, densely pubescent, nearly 1 cm. long. "Recepta- cles, long-peduncled, solitary, or in pairs from the axils of the leaves, globose, densely tomentose, (> to 7 mm. in diameter, abruptly constricted at the base into a slender stalk 3 mm. long, at the juncture of this stalk with the pedicel are three broad, obtuse bracts 1.5 mm. long; peduncle proper pubescent, 1.5 to 2 cm. long; umbilicus, rather prominent, 3 mm. in diam- eter. Male ilowers long-pedicellate, mixed with gall flowers all over the interior of the receptacle, evidently the same as in Ficus macropoda Miq. 'type specimen collected at Baler, Province of Principe, Luzon. No. 1059. September, 1902. Tagalog, Malananca. A species of the section Eusyvc, related to Ficus uiacropoda Miq., and /•'. pcdunculosa Miq., both species being found in the Philippines, the former endemic, the latter being also known from Beroe and Celebes. It is, how- ver, more closely related to the former, from which it is distinguished by its smaller leaves, which are acute, not emarginate at the base, much longer petioles, punctate under the surface of the leaves, and very much longer peduncles. See King, Ann. Bot. (Hard. Calcutta. 1: 144, 145. pi. 182, /,S3. Ficus i»ski;i>oi»alma Blanco, Fl. Filip. ed. 2, 47:'). 1S45, ed. 3, 3: cm. in diameter, the leaves which are from 5 to 8 dm. long, being all crowded at the apex of the stem, giving the plant a palm-like appearance. The leaf scars are very large and prominent, as are the lanceolate, acute, stipules, which are from 5 to 7 cm. long. The receptacles are dark green, ovate, usually more or less angular, 3 to 4 cm. long, usually in pairs, on short peduncles in the axils of the leaves. This species is represented in our herbarium by No. 983, Calapan, Min- doro, April, 1903. and No. 1958, Pagbilao, Province of Tayabas. Luzon, April, 1903. It is known by the Tagalogs as l\io(/-nio(iatK and by the Visayans as Sulamuxj. l Nov. App. Fl. Filip. 201. 18S3. 10 MYRTAOEiE. Xantiiostemon speciosum Merrill, sp. nov. A small tree, about 10 m. high, with ovate or obovate leaves and terminal cymes, bearing from 2 to 4 showy crimson flowers. Bark gray, ultimate twigs with scattered hairs. Leaves alternate, ovate, or obovate, obtuse or rounded at the apex, tapering to the cuneate base, to 8 em. long, 3 to 4.5 em. wide, entire, coriaceous, nearly glabrous except for a few scattered striate hairs on both surfaces, beneath black-punctate, nerves 1) or 10 pairs, not prominent, anastomosing near the margin; petioles, 1 cm. long or less, with few appressed hairs. Inflorescence terminal, 4 to 5 cm. long, 2 to 4 flowered; peduncles pubescent; pedicels 2 to 3 mm. long; bracteoles linear, 5 mm. long, pubescent. Calyx tube 0.5 mm. long, 1.5 cm. in diameter, somewhat pubescent, the lobes five, triangular, spreading, acute, sparingly pubescent, 3 to 4 mm. long, alternating with the calyx lobes are five prominent depressions in the calyx tube. Corolla spreading, the petals crimson, orbicular, 6 mm. long, 8 mm. wide, slightly ciliate on the mar- gins. Stamens about 20, exserted, crimson, arranged in a single series; filaments about 2 cm. long; anthers 2.5 mm. long. Ovary 3-eclled. Style 2 cm. long; stigma unknown. Fruit unknown. Type specimen No. 682, collected in a dry, open, grassy valley near llalsey Harbor, Island of Culion, February 12, 1903. A tree about 10 m. high and 3 dm. in diameter, with exceedingly hard, dark-colored wood. This species is quite distinct from Xantiiostemon verdugonianus Naves, the only other species of this genus found in the Philippines. Its distin- guishing characters are its much larger flowers, very short but broad calyx tube, larger petals, crimson filaments, etc. Xanthostemon verdugonianus Naves, in F. Yill. Nov. App. Fl. Filip. 82. 1883; Fl. Filip. ed. 3, t. W0; Vidal, Sinopsis, Atlas, t. /,!). /'. A'. 1883. This species is represented in our herbarium by No. 428 (Ahem), Island of Tinago, 1901 (in fruit), and by No. 34 (Howard Long), ITacer, Province of Surigao, Mindanao, May 20, 1003 (in flower). This species grows to a much larger size than Xantiiostemon speciosum, reaching a height of 50 m. It is known by the Visayans as Magcono and Mancono. Is inuch prized for its exceedingly hard durable wood, and is said to be abundant in the Prov- ince of Surigao. It is well represented by the figures of Naves and Vidal cited above. So far as is known, with one exception, the two Philippine species here noted are the only ones of this genus that have been discovered outside of Australia and New Caledonia, and up on the present time no species of this germs has been discovered in New Guinea although one species has been described from Celebes. P>oth of the Philippine species differ from the other species in the genus by their smaller number of stamens. OLEAOJ^K Mayepea cuminciana (Vidal). Linocicra cumingiana Vidal, Phancrog. Cuming.

Zizyphus arboPvEA Merrill, sp. no v. A large tree, reaching the height of 40 m., with a diameter of 00 cm. above the buttresses, which extend to a height of about 3 m. on the trunk, with broad, ovate, often subcordate leaves, which are glabrous on both sur- faces, and globular, minutely rufous-tomenf ose drupes about 2 cm. in diame- ter. Brandies unarmed, the younger ones more or less rufous-pubescent. Leaves broadly ovate, acute, the base often somewhat oblique, acute or sub- cordate, 8 to 12 cm. long, 4 to 7 cm. wide, entirely glabrous, with three strong unbranched, vertical nerves, the secondary nerves leading from the lateral vertical nerves, 10 or 12, prominent, margins entire or sub-crenate : petioles about 1 cm. long, often slightly pubescent. Inflorescence of axillary peduncled cymes, usually forming a terminal cymose, leafy, panicle; pedun- cle 3 to 4 cm. long. Flowers unknown. Drupe globose 2 cm. in diameter, minutely rufous-tomentose, 2-seeded, the pulp scanty, the endocarp bony. The following specimens represent this species, all from the Province of Tayabas, Luzon. Pagbilao, No. 1929 (type)., Feb. 11, 1903; No. 1983, March 14, 1903; Cuinayangan, No. 2017, April 13, 1903. A frequent tree on the hills and table lands, the timber being used for the construction of bancas (native canoes) and houses. It is not. however, durable when exposed to the weather. Tagalog, Ligaa and Danlic A species distinguished by its large size, well developed buttresses, spine less branches, and glabrous leaves. RHIZOPI-IORACE2E. Bruguiera RiTCiiiEi Merrill, sp. nov. A shrub or small tree 12 m. high or less, with lanceolate leaves, oblong, cylindrical striate calyx, and xcry short erect calyx lobes. Trunk 25 cm. in diameter or less; bark rough. Leaves ovate-lanceolate, somewhat, coria- ceous, 6 to 11 cm. long, 2 to 3.5 cm. wide, acute, tapering to the base, gla- brous, slightly pale, and densely punctate beneath, nerves about 10 pairs, not prominent, anastamosing near the margin; petioles 2 cm. long. Inflor- secence axillary; peduncles solitary, 1.5 to 2 cm. long, bearing several flow- ers, of which usually only one develops. Flowers unknown: fruiting calyx, cylindrical, somewhat channeled, 1 to 1.5 cm. long. 5mm. in diameter, abruptly tapering to the pedicel, which is 1 to 1.5 cm. long; calyx lobes, 8 very short, acute, erect, 3 mm. long. Fruit in the fundus of the calyx, with the growing radicle protruding 10 cm. or more. 12 This interesting and well-marked species anus first collected at Pol a, Min- doro, in mangrove swamps, by Mr. J. W. Bitchie, while making some inves- tigations on tan barks and dye woods for the Forestry Bureau, in May, 1903, distributed as number 2403 (type), No. 2487, from Guinayangan, Province of Tayabas, Luzon, May, 1903, also represents this species. It is known by the Tagalogs in Mindoro as flangaraij and Hagalay, while the Tagalogs in Tayabas call it Pot of an. A species at once distinguished from others in the genus by its elongated, cylindrical calyx, and very short calyx lobes. RUTAOE.E. Ae(;i,e (jlutinosa (Blanco). (Liuionia yhilinosa Blanco, Fl.

SAIMNDACEJI Tristika pi kescens Merrill, sp. nov. A small or medium sized tree, 10 to 12 m. high with densely rusty pubescent leaves, inflorescence, and young branches. Leaves pinnate, the densely rusty pubescent raclris 10 to 12 cm. long; leaflets 4 to 5 pairs, lanceolate-ovate, to 8 cm. long, 1.5 to 2.5 cm. wide, densely rusty pubescent beneath, and sparingly so above, the apex blunt or obscurely acute, the margins entire, nerves about 15 pairs, petiolules 2 to 3 mm. long. Fruiting panicles about 15 cm. long, the rachis and branches densely rusty pubescent. Calyx lobes five, pubescent". Fruit triangular, ovate. 2 to 3 cm. long, rusty pubescent, woody, the wings narrow near the base of the fruit, about 5 mm. wide above, the three joining and terminating in a short point at the apex of the fruit, the three cells lined with a dense, white woolly tomentum. Type specimen No. 2842. Bosoboso, Province of Bizal, Luzon, July 19, 1903. Tagalog Am pay. A very distinct species, at once distinguished from the other two species in the genus by its dense rusty pubescence. Tristara tripicra Radlk.. the only other species of the genus from the Philippines, is almost glabrous, with much larger leaves and larger fruits than in Tristira pubeseens. The flowers of no species of this genus are known at present. SAPOTACE.E. Although the genus Palaqnium was based on Philippine material, very little definite information has been available regarding the several species found in the Archipelago. Blanco in establishing the genus described three species, all of which are known to us today. Fernandez- Villar credits seven species to the Archipelago, of which one is described as new and two of which were erroneously credited to the Archipelago. Vidal notes but three species, while in the present (.numeration 11 species are considered. All the material on which the present enumeration is based has been col- lected since the American occupation, and as more thorough collections are made we may expect that this list will he considerably extended.

The trunk reaches a diameter of 70 cm. and the buttresses are not well developed. This species yields but a small amount of latex, which is not utilized by the. natives. It is named in honor of Mr. P. T. Barnes, collector for the Forestry Bureau, who first secured specimens. Visavan, Nato. 14 Palaquium latifolium Blanco, Fl.

This characteristic species is represented in the herbarium by No. 1G75, Antipolo, Province of Rizal, Luzon, and Nos. 1941 and 1919, Pagbilao, Prov- ince of Tayabas, Luzon. It is readily distinguished by its obovate, obtuse leaves, which are 2 or 3 dm. long and densely rusty-tomentose and shining beneath. Tagalog Alacap; Palac palac. Palaquium qleiferum Blanco, 1. c, 405. {Bassia old [era A. DC, 1. c, 198; Dichopsis oleifcra V. Vill., 1. c, 125.) This species is apparently closely related to the preceding, but is distin- guished by its narrower leaves, which are acute, not obtuse, and which are oblanceolate in form. The seeds of this species yield an oil which is utilized by the natives. It is represented in the herbarium by the following speci- mens, all without fruit or flowers: No. 1402, Arayat, Province of Pam- panga, Luzon, and a specimen from the same province without locality, col- lected by M. Martines. A specimen from Mindanao, No. 21 (Sherman), appears to belong here. When more complete material is secured we shall be better able to judge the validity of this species.

This species yields much of the gutta-percha produced in Mindanao, and is known to the Moros as Calapia. Palaquium sp. indet. This species, which is certainly undeseribed, is represented in the herba- rium by a single sterile specimen, collected at lligan, District of Misamis, Mindanao by A. Alga. The leaves are glabrous, narrowly lanceolate and long-acuminate, 15 to 20 cm. long and 4 to G cm. wide, the nerves 1(5 to 18 pairs. Moro, Buruan.

This species, which must be considered as the type of the genus, has been imperfectly known, and previously no specimens have been collected repre- senting the species since it was described by Blanco. It is represented in the herbarium by the following specimens: No. 42 Ahern. Dalupaon, Prov- ince of Camarines, Luzon, February, 1901. Dulitan; No. 213(5. Pitoga, Province of Tayabas, Luzon, April, 1903. Dolitan; No. 2042, Guinayangan, Province of Tayabas, Luzon, April. 1903. No. 109(5, Baler, Province of Principe, September, 1902. B alibis; No. 1991, Pagbilao, Tayabas, locally known as Bctis, is also referred here, but the petioles of this specimen are much longer than in the other numbers referred to this species. The name Bctis is usually applied to Illipc bctis. The only native name Blanco gives for Palaquium lanceolatum is Bagalangit. 10 Palaquium gutta Burck. and Palaquium polyantjium (Benth. et Hook). These species reported from Luzon by F. Villar, 1 are manifestly based on misinterpretation of species and should be excluded from the Philippine flora, as neither species extends to this region. Just what species F. Vil- lar had in mind it will be impossible to determine, as no herbarium material has been preserved and no descriptions are given. STEMONACE,K Stkmona philippinensis Merrill, sp. nov. A slender glabrous twining vine 1 to 2 m. high, or more, with alternate, deeply cordate, 9 to II nerved leaves, and small purplish-red axillary flowers. Leaves ovate-cordate, tapering to the slender acuminate apex, 7 to 10 cm. long, 3.5 to 5 cm. wide, shining, the sinus at the base nearly 1 cm. deep; petioles 1.5 to 2 cm. long. Peduncles 2 to G cm. long, solitary; bracts small, lanceolate, (lowers purplish-red, 1 cm. long, the segments of the perianth lanceolate, acuminate, 7 to 9 nerved. Stamens erect, 9 to 10 mm. long. Typo specimen No. 3001, Island of Masbate, August, 1903. Visayan, Sigid. A species perhaps most closely related to Stcmona minor Hook, f., a species of Ceylon and Malabar, but differing from that species in its larger leaves, which have more numerous nerves, smaller flowers and other char- acters. Stemona tuberosa Lour. This species was found at Point Separation, Paragua, February 18, 1903, distributed as No. 792. No species of this family has previously been reported from the Philippines. TILIACEiM (Jolona LONdiPETiOLATA Merrill, sp. nov. A small tree with nearly glabrous, long-petioled leaves and glabrous fruits. Young branches pubescent, becoming glabrous. Leaves ovate- lanceolate, 10 to 15 cm. long, 5 to 7 cm. wide, rounded or somewhat acute at the equilateral base, abruptly tapering to the long-acuminate apex, the upper surface scabrous and with few hairs on the midnerve and veins, •glabrous beneath, the nerves prominent, 5 pairs; petioles 2 to 3 cm. long, beset with brown, stellate hairs; stipules lanceolate, acuminate, about 12 mm. long. Panicles terminal, 18 cm. long, the lower branches 8 to 10 cm. long. Flowers unknown. Fruit obovate, 2 cm. long. 1.5 to 2 cm. broad, the wings about 0.5 cm. broad; pedicels about 1 cm. long. Type specimen No. 479 G. P. Ahern. Mariveles, Province of Bataan, Luzon, January 4, 1902. A very distinct species, perhaps most closely related to Colona blaneoi, but with smaller fruit which has much narrower wings than in that 1 Nov. A pp. 124. 1SK3. 17 species. It is distinguished from all described species in the genus by its long petioles. Tagalog, Anilao lalaqui. Colona blancoi (Rolfe). (Columbia blancoi Rolfe, Journ. Linn. Soc.

This form is in all respects worthy of specific rank, di tiering from Colona scrratifolia in its much larger, broader leaves, longer petioles and larger fruits. It is represented in the herbarium by No. 1703, Antipolo. Province of Rizal, Luzon, March, 1903, and is known to the Tagalogs as Manned. Colona serratifolia Cav. Ic. 4: 47. t. 310. 1797. {Columbia amcricana Pers. Syn. PL 2: 66. 1807; C. serratifolia DC. Prodr. 1: 512. 1824; C. incqualerata Turcz. Bull. Soc. Nat. Mosc. 31: 233. 1858: C. anilao Blanco, Fl. Filip. ed. 1, 054, 1837.) This variable species is at present represented in the herbarium by no less than sixteen specimens, representing a distribution from northern Luzon to Zamboanga and Davao in Mindanao. The vegetative characters of this species are exceedingly variable and it is probable that some authors would consider that the material here referred to Colona serratifolia, rep- resents several species; however, no valid characters can be found by which to separate the several forms. Columbia anilao, considered as a distinct species by F. Villar, is undoubtedly identical with Colona serratifolia. Columbia serratifolia Blanco, non DC, is a species of Oreuia. Colona scrratifolia is known to the natives of the Philippines as Anilao. TllIUIUFETTA TROCUMIiENS Foist. This species is found along the sea coast from Madagascar to Australia and Polynesia, but previously has not been found in the Philippines. It is at present represented in the herbarium by No. 2387, Pola. Mindoro, May, 1903, and No. 3373, Pasacao, Province of Camarines, Luzon. If is appar- ently a rather common constituent of the strand vegetation in the Phil- ippines. VERBENACE^K. Vjtex ovata Thunb. Fl. Japon. 257. 1784. (V. rcpcns .Blanco, Fl. Filip. ed. 1, 513, 1837: V. frifoliala Linn. f. var. uuifoiiala Schauer in DC. Prodr. 11: 083. 1847.) This widely distributed species is apparently distinct from V. frifoliata L. f., to which it has been reduced by various authors. It is represented in our herbarium by No. 323, Aparri, Province of Cagayan, Luzon, June 22, 1902, and No. 898, Calapan, Mindoro, 1903. At both of these localities the trailing form only was found. On Lubang Island, however, in April, 1903, this form was found associated with Yilcx frifoliala L. f., and no intergrading forms were observed. V. trifoliata L. f.. was always an erect shrub, 2 to 3 m. high, with trifoliate leaves; while 1". orata Thunb.. was erg. This very common grass is said by Hooker- to have been introduced into Ceylon from America. It is possible that this was originally an American plant, but at the present time it is found throughout the tropical and sub- tropical regions of the world. It is now one of the most common and most widely distributed species in the Philippines, but is usually found only in the vicinity of towns. From its habitat and distribution it is evident that it is not a native of the Philippines, but it is impossible to determine the original home of the species at this time. Zea mays L. Indian corn is too well known to need much discussion, but was probably one of the earliest of the American plants introduced into the Philippines, it is now generally cultivated throughout the tropical and temperate regions of the world. It is extensively cultivated in the Philippines and is universally known to the natives as Maiz. labiate^;. Hyptis spp. Six species of Hyptis, all presumably of American origin, are enumerated by F. Villar as being found in the Philippines, and at least four of these species are common and widely distributed in the Archipelago. Hyptis spicigcra Lam., //. capitata Jacq., H. brcvipcs Poir., II. suaveolens Poir., 11. spicata Poir., and 11. pcctinata Poir., are the species credited to the Archipelago by F. Villar. The first four of these species are common and widely distributed in the Philippines, //. spicigcra and //. suaveolens being usually found in waste places in the vicinity of towns, while II. brcvipcs and //. capitata are found not only in the vicinity of towns, but also distributed along trails in the mountains and in open lands generally. The last two species are unknown to me at present. Probably all these species were introduced into the Philippines accidentally in packing mate- rial or by other methods. One species is noted by Mercado, //. capitata, in 2 F1. Brit. 2nd. 5: 439. 2 Trimen & Hooker, Fl. Cevlon 5: 12*2. 1900. 29 the last third of the sixteenth century, while Blanco in 1837 notes four species. The various species are known to the natives by such names as Com barcombaran, Linga Ungahan . Palapasagm, Locoloeo, Pansipansihan, etc. MALPHIGIACE.E. GaLPIIIMIA GLAICA Cav. This ornamental shrub is somewhat cultivated in Manila, but is not spontaneous. This species has not previously been recorded from the Phil- ippines, and is probably of very recent introduction. MALVACEAE. Malaciira ijracteata Cav. F. Villar credits this species to the Philippines, but the plant he identi- fies as this species is Malachra linear ihba Turcz.. a species described from Philippine material. We have at present no available description of Mala- chra bracteata, and it is possible that F. Villar was correct in his identifi- cation of the Philippine plant with this American species. The plant in question is common and widely distributed in the Philippines. MARANTACE.E. Maranta arundinacea Linn. The well-known arrowroot plant is at the present time rather common in the Philippines, where it is cultivated both for ornamental purposes and for its edible roots. It is frequently subspontaneous about towns. This species is noted by Blanco in the second edition of his Mora de Filipinas, but when the plant was introduced is unknown. It is known to the natives as Aroro, Aroni, and Array -rou, evidently corrupt rt>ns of the common English name of this plant. LEGUMINOSEJE. Araciiis hypog.-ea Linn. The "peanut" is frequently found in cultivation in the Philippines and generally throughout the East. It is. however, undoubtedly of American origin, having been introduced into the East at an early date. So far as is observed this species is nowhere spontaneous in the Philippines. It is known to the natives by the Mexican name Cacuatc, but more 1 commonly bv the name Mani. Ctesalpinia ruLCHERRiMA Swartz. A small shrub, with showy racemes of red flowers, widely distributed in the Archipelago, but usually found in the vicinity of towns. The natives have no name for this species other than the Spanish word cal>all from which it is very evident that this species has been introduced into the Phil- ippines since the Spanish occupation. The native country of this plant is not clearly known, but is probably tropical America. At the present time it is found in cultivation throughout India and Cevlon and elsewhere in the 30 tropics. The other species of this genus most closely related to dwsalpinia pulcherrima are, it is believed, all natives of tropical America. According to F. Villar 1 this plant was figured but not described by Mercado in his Libro de Medicinas, written in the last third of the seventeenth century, evidence that it was introduced early in the Spanish occupation. Cassia alata L. A small shrub with yellow flowers and winged pods, common about towns throughout the Archipelago, but certainly not a native of the Philippines. This species is said to be cosmopolitan in the tropics, but the Mexican name Acapulco, commonly used by the natives in designating this plant, would indicate an American origin, at least for the plant as found in the Philip- pines. It is extensively used by the natives in the practice of medicine. Cassia oirrrsiFOUA Linn., C. uirsuta Linn., C. occidentalis Linn., and C. soph era Linn. All these species are of American origin, but are now generally dis- tributed throughout the tropics of the Last. They are all herbaceous plants or undershrubs, and are usually found in waste places in the vicinity of towns. Like the preceding species they all belong to the section Senna, and several of the species are utilized by the natives in the practice of medicine. Da lea nigra Mart, et Call. An erect herbaceous plant 1 to 2 feet in height, with pinnate leaves and capitate heads of purple flowers, common and widely distributed in the Archipelago, growing in open grass lands and in cultivated places. It is not known when or how this Mexican species was introduced, but its intro- duction was probably accidental and at an early date. Jt is now spon- taneous and thoroughly naturalized in the Philippines. Blanco described this plant in 1837 as Amorpha alopccuroidcs Willd. It is known by the natives under several names, such as Dururn/ parany, Afjoyo, tfampaloc- sampalocan, damani/i, etc. Mimosa runic a L. A low prostrate herbaceous plant with numerous globose heads of pink flowers and sensitive leaflets. The native country of this species is not clearly known, but it is probably tropical America. It is now spontaneous throughout the tropics of the East and is one of the most pernicious weeds with which the tropical agriculturist has to deal. In the last third of the seventeenth century it was evidently known in the Philippines only by the Spanish name Hicrba mimosa, as it is classified under this name by Mercado. To-day it is known by the Tagalogs as Damohia and Macahiya, and by the Visayans as lluya luiya. It is to-day one of the most common and widely distributed species in the Philippines. Cliricidia maculata H. B. K. A small tree with pinnate leaves and white or pinkish flowers, introduced from tropical America, according to F. Villar'- in the eighteenth century. It was described by Blanco in the first edition of his Flora de Filipinas as >Nov. App. Fl. Filip. 09, 1883. 2 L. c, 59, 1883. a new species Galedupa pungam. This tree is one of very rapid growth and was introduced for the purpose of furnishing shade for cacao trees, for which purpose it is still used. It is universally known by the natives by the Spanish name of Madre cacao. This species is at present cultivated in many cacao plantations and is also spontaneous in many localities. It is generally distributed throughout the Archipelago. Indigofera anil Linn. This species, known locally as Anil, was introduced from America, and with Indigofera Unctoria is somewhat cultivated for indigo, and spon- taneous. It is frequently known by the name Taguni. which is also applied to other species of the genus. Leucvena glauca Benth. A shrub with dense globose heads of white flowers, common in waste places about Manila and other towns in the Philippines. This species is undoubtedly of American origin, but is now generally distributed through- out the tropics. It is evidently of comparatively recent introduction in the Philippines, as it is not considered by Blanco as late as the year 184"). Some Tagalogs know this plant by the name of Agho. but most natives have no name for the species. PlTKECOLOUIUM saman Benth. This species is very abundant in Manila, being extensively planted for shade purposes and is apparently entirely adapted to the climatic condi- tions existing here. It was introduced from the West Indies by Don Zoilo Espejo, the first director of the Botanical Garden in Manila, in about the year 18(H). Without exception it is the most valuable shade tree we have today in the city, and is being more extensively used for this purpose every year. A large portion of the Botanical Garden is occupied almost exclu- sively by this species, which is one of the very few trees that seems to thrive under the conditions there existing. It does not fruit freely in Manila, although it produces an abundance of (lowers. So far as is known the natives have no name for it. In the West Indies it is known as the '•rain tree" from the fact that at the approach of a storm the sensitive leaves droop, the leaflets becoming closed and remaining in this position throughout the duration of the storm. The lea (lets also close at night. PlTlIECOLOBIUM DU-LCE Benth. A medium-sized tree now very common throughout the Philippines, intro- duced from tropical America in early times by the Spaniards. It is con- sidered by both Mercado and Camel 1. and known by the natives, as Cam.an- chilcs. It is much prized by the natives for its white or pink, pulpy, fleshy, edible aril, which half surrounds the seeds. Prom the Philippines it has been generally distributed throughout the tropics of the East, and is com- monly cultivated. In India it is known as the "Manila tamarind," prob- ably from the similarity of its fleshy aril to the fleshy mesocarp of the true tamarind (Tamarindus indica). The natives of the Philippines use the bark of this species extensively for the purpose of tanning leather. 82 PilASKOI/US L UN AT US Linn. r rhis universally cultivated bean is probably of American origin, but is now found throughout the tropics of the world. It is common in the Phil- ippines in cultivation, and is known to the natives as flaba, Zabacltc, and Pafinu the two former words being of Spanish origin, evidence that the plant was introduced into the Philippines by the Spaniards. Pkosopis juli flora DC. A shrub with spiny branches and cylindrical spikes of yellowish flowers, common about Manila and widely distributed along the shores of Manila Bay, in many places exclusively occupying large areas. This species is a native of tropical America and has evidently been introduced into the Phil- ippines at a comparatively recent date, as it is not considered by Blanco or the earlier authors. It is entirely adapted to conditions here and grows as though it were a native rather than an introduced plant. Naves considered it as a native plant and described it as a new species Prosopis nidaliana, first in a periodical published in Manila and later during the same year (1877) in a pamphlet entitled "Prosopis vidaliana," giving a very full description with two plates. It is known by the Tagalogs as Aroma, a name also applied to Acacia farncsiana Willd. LILTACEiE. Yucca aloifotja Linn. This and two other species of this genus of American origin are noted by F. Villar as being cultivated in Manila. None of the species are spon- taneous. MYliTACEiK. PSIWUM (JUAYAVA L. A shrub or small tree with white flowers and edible fruits, introduced from tropical America at a very early date and now one of the most com- mon and widely distributed species in the Archipelago, being found not only in and about towns and villages, where it is cultivated for its edible fruit, but also in the wilder and more inaccessible portions of the Archipel- ago, its wide distribution being due to the fact that the numerous small seeds have been disseminated by birds and monkeys. This species is found generally throughout the tropics of the East. \n the Philippines it is known by the natives as (luayabas and Bayabas, names of Spanish origin. Several varieties of this species are also found in the Philippines. NYCTAGINACE.E. BoUUAI NVILLKA SPECTAI51IJS Willd. This striking ornamental plant, now found in general cultivation in trop- ical and subtropical regions was introduced from tropical America, some time between the years 1845 and 1880, as it is considered by F. Villar, but not by Blanco. It is commonly cultivated for ornamental purposes in Manila, but is not spontaneous. OLACAVEAZ. XlMEMA AMERICANA Willd. It is not. known whether this plant is strictly of American origin. At the present time it is found universally throughout the Tropics. It is reported from the Island, of Panay. by P. Villar, hut no authentic speci- mens are available at present. PAPAYERAnE.R A H( J K M ON K M K X I C A N A L . This is the only species of the J'aparcrncciv found in the Philippines, the time of introduction being uncertain, as it is not considered by Mercado nor Camell, although it is described by Blanco in the year 1S:J7. Tins plant is spontaneous in waste places and cultivated grounds throughout the Archipelago. It is extensively used by the natives in the practice of medi- cine and is known by the Uocanos as Vavhumbu. By the Tagalogs it is often called Diluario, but both these names are also applied to various other species. PAKKIELORArE.E. (.■A RICA PAPAYA L. The papaya was introduced from America in the seventeenth cent in y, according to ¥. Villar, and is now found in cultivation in all parts of the Archipelago, being much prized for its fruit. It is now generally cultivated throughout the tropics of the. world. In the Philippines it is known to the natives as Papai/a or Cui/upas. PAvSSIfloua serrulata dacij. This and three other species of this genus of American origin are enum- erated by F. Villar, but all are cultivated, none being spontaneous in the Archipelago. POLYOOXArE.E. Antigonon cordatim Mart, et Oal. This highly ornamental vine is commonly cultivated in Manila, but is nowhere spontaneous. It is of comparatively recent introduction, and the common name /'/ores' da ftinipipur would indicate that the plaid, was intro- duced into the Philippines from Singapore, and not directly from America. SAP()TACE^E. ACIIRAS SAPOTA L. This tree is generally cultivated in the Philippines for its fruit and was introduced from America at an early date. In tropical America it is culti- vated extensively, not only for its edible fruit, but for the gum known as "gum chicle," which is secured by slashing the bark and collecting the gum as it is deposited in the wounds. It is in constant demand, as it is the basis of most of the chewing gum so extensively used in the United States. 8200 3 34 Little or no use is made of it in the Philippines. This species is generally cultivated in the tropics of the Hast. It is known to the natives of the Philippines as Chicos and Sico. LrcuMA mammosa (Jaertn. This tree, like Achras sap)ta, is generally cultivated in the Philippines for its fruit, and was probably introduced at about the same time as the latter species. Blanco, in 1837, stated that it appeared to be indigenous, from which it is evident that it was very common in the Archipelago at that time, and consequently must have been introduced at a very early date. Lucuma mammosa is evidently not generally distributed in the East, as Hooker does not mention it in his Flora of British India. It is known to the natives of the Philippines as Mamcy or Ohico-mamcy. SIMARUBACEiK. QlJASSA AMARA LillTl. This American species is of comparatively recent introduction, but cultivated specimens only have been observed. SOLANACEjTC. Cestrum nocturnum Murray. This species was introduced from America in the year 1850, according to F. Villar, and is now found in general cultivation for ornamental purposes in Manila and in other large towns in the Archipelago. Its flowers are exceedingly fragrant at night, and it is commonly known as Dama de noche. Lycopersicum esculentum Mill. The tomato is too well known to need much discussion. It was intro- duced from America at a very early date and is now extensively cultivated, and also spontaneous, throughout the Archipelago. The spontaneous form lias evidently reverted to the original form of the species, as the fruits are of a very small size. It is universally known to the natives by the Spanish name To mates. Nicotiana tabacum Linn. This and several other species of this genus are extensively cultivated throughout the Archipelago, tobacco being one of the most important crops produced in the Philippines, the value of tobacco and cigars exported being exceeded only by hemp, sugar, and copra. The best grades of tobacco are raised in the valley of the Cagayan River, in Northern Luzon. Tobacco was introduced at an early date, and its cultivation here has been attend- ant with many abuses, especially during the period of the Government monopoly. It is universally known to the natives as Tobaco. Piiysalis peruviana Linn. This species is somewhat cultivated for its edible fruit, but is apparently not common in the Archipelago. Several other species of Physalis are found as weeds in the Philippine Islands; some of these may prove to have been of American origin. Solan i tm tuberosum Linn. The jwtato was probably introduced at an early period, and is now gener- ally cultivated, especially in the mountainous regions of the Archipelago. The tubers are, however, usually very small and of an inferior quality. TIL I ACE.*]. MUNTINCIA OALAHUKA L. A small tree of rapid growth with white dowers and small purplish edible fruit, common in and about Manila and the larger towns in the Archipelago, known by the natives as Datilvs or Ra files. This species is evidently of comparatively recent introduction, as Blanco does not con- sider it in his Flora de Filipinas. either in the first or second edition. It is a native of the West Indies and is now spontaneous here in manv regions, especially in Luzon. TlIKOHROMA CACAO L. Cacao, known also to the natives of the Philippines by this name, is now found in general cultivation as one of the staple crops throughout the Archipelago. According to Blanco.' it was first introduced from Mexico in the year 1070 by a pilot named Pedro Bravo de Laguna. The quality of cacao produced in the Archipelago is very good, but the cultivation of the tree is carried on in a most primitive manner, little or no attention being paid to insect pests or fungus diseases, to the attacks of both of which the trees are very susceptible. urticacej:. Piuka muscosa Li mil. This small species, a native of South America, is one of the most common plants about Manila at the present time, being especially abundant on and about damp walls. When it was introduced we have no record, as it has not previously been recorded from the Philippines. This species is also found in Java and British India. No native name is recorded for this species, which, judging from its abundance and wide distribution, must have been introduced into the Philippines many years ago. VEKBENACE.E. Dukanta plumiehi Jacq. This shrub, like J'elraca rohibilis, is somewhat cultivated in Manila for ornamental purposes, and was probably introduced at about the same time as the latter. According to Hooker it is also commonly cultivated in British India. Lam tan a camara Linn. This species is abundant and spontaneous in waste places about Manila and other towns in the Archipelago. It is a shrub 5 to feet high with X F1. Filip. ed. 1. 001. 1837. 86 mi morons heads of pink, yellow, or red flowers, and aromatic leaves. The date of its introduction is unknown, although it is considered by Blanco in 1845 but not in 1837. Lantana camara is now widely distributed in the East, and is known in the Philippines as Coronitas. Two other species of Lantana reported from the Philippines by F. Villar, are probably but forms of the above. Petraea volttbitjs Linn. This American plant is occasionally found in cultivation for ornamental purposes in Manila. It is a vine with terminal racemes of sm 11 blue flowers, and must have been introduced sometime between 1845 a* 1 1880. O UNIVERSITY OF MICHIGAN 3 9015 04878 4402
