NEW OR NOTABLE ALLTONIACEAE
It differs from the latter, however, in having slender rather than subcoriate blades, which are acute at the same time, in having slender blades rather than subcoriate leaves, which are acute at the base and more broad above the middle, rather rounded at b .. and wider at or below the middle. Related to them, I uhia fragram, but distinct in the large, almost glabrous staminate perianth and the glabroUB branches of the inflorescence,.

NEW OR NOT,ABLE SPECIES OF GERANIUM FROM COLOMBIA AND VENEZUELA
SpecimeI1fl agreeing very well with the original description of this species was collected in the Paramo de Timotes, State of T6.chlra, Venezuela., at an altitude of 3,000 to 3,500 meters, in March, 1910, by Dr. Knuth, in his monograph of the genus, places BpfICies doubtfully in the section Gracili&.l If the present BPecimen is kouectated, the species may better be placed in another. Plant peren}lia.l, densely cespitose with much thickened caudicea from a stout elongated frutC8cent root; leaves and flowers all basal; stipules 10 to 15 mm.
National Herbarium There are several collections of this species, which Knuth has cited.
WERCB'T.EA, A NEW GENUS OF MALVACEAE
Wercklea is a member of the subfamily Hibisceae and is closely related to the genus Hibiscus. WerckM, a collector of this species, who botanized extensively in the little-known regions of Central America. The tree grows in the humid forest on top of the mountains around La Palma, a region that is blown by the humid trade winds from the east.
Low shrubs, or sometimes herbaceous plants woody only at the bays, with slender or stout branched 8stems; pubecence ususally abundant and composed of stellate haUai leaves usually broad, petiolate, toothed j sti'pulee narrow, generally deciduoU8i bloom6Cence capitate or 8ubcapitate, 3 to 10-flowered, on a long ax: ilIary peduncle, or sometimes sessile; bracts large, similar to the leaves, 1 or 2 subtending each head of flowers and usually concealing aurpaas and the carpels; bracts of the sheath 8 to 11, in a single whorl, each usually with a peltate enlarged blade.
1'9 E GENUS LOPIMTA
Many of the species of Malache (betfAlr known as Pavonia) are widely tropical forests. A member of the subgenus Typhalaea, but not closely related to any described speed of the group. Specimen type leaves suggest les.fteta of Clnnatis virginiana and ita sllies.
The Dame arach1WitJea is given to the species of Western Mexico o, not because of the chan.cter of the pubescence, as one might expect, but on account of the resemblance of the fruit and bracts to the body and legs 01 a spider.
NEW OR NOTABLE EBENACEAE FROM MEXICO
Palmer made two additional collections of the same species near Victoria, Tiltnaulipas (Nos. 116 and 369). The shape of the ash lobes suggests Diospyros T o aei, but of course there are no leaves. Despite the lack of flowers, there is little doubt that this species is correctly referred to section Pa.ralea.
The proposed species is noteworthy because of the unusual development of the calyx in antbooiA.
A NEW STYRAX FROM PANAMA
Also in the latter, the sepals are not pubescent throughout and are more acute. However, that species has much smaller leaves (7 to 12 em. long), shorter pedicels (2 to 3 mm.), and paniculate inflorescences. Early in December, 1911, Pittier collected another epociBH of the genue, Styrax argtnku.t Presl, in the vicinity of Oli, Province of Coc1~, Panama (No. 5076).
This plate was quoted by Linnreus in the second edition of the Species Plantarum' under SpermfU()ce kispida.
TIONS OF TWO NEW SPECIES
The venation of the leaves is very similar to that found in icms of the genus Campyloneurum. In.the type collection the bracts are purple or greenish purple, more or less tinged with yenow, while in the second collection they are pale yellow or greenish yellow. The apices appear very distinct in the Clump of the inflorescence, although BOrne of the Brazilian species likewiae have 3-parted heads.
Similar to DuggetUJ pana..m in ilia 4-celled fruit, but easily distinguished by the small, almost s()fliate leaves, the narrow and longer calyx, and the densely pubescent fruit.
NEW OR NOTABLE SPECIES OF ARCYTOPHYLLUM
The Colombian plant has much narrower leaves than the Venezuelan plant, but is otherwise indistinguishable. OUB, crowded; leaflets broadly ovate, divided at the top into several bristly lacinires; leaf side 6 mm. Weddell based this on three collections from Pamplona and Ocaiia provinces in Colombia.
