Enter TL S, National Herbarium, no. 989608, collected on an open rocky slope along the route from Los Amates to Izabal, Department of Izabal, Guatemala, May 31, 1919, by S. This species is a member of section Stypo8 This species is a member of the group Nephromerta and is closest to Meibomia purpusli (T. S, Brandeg,) Blake,* but can be distinguished by its much broader leaflets, pubescent with longer rufescent hairs and by its larger lobes. , which is not beaked at the tip,. However, the species is described as having the small leaves finely pubescent below and obliquely obtuse at the base, the bracts on the stem lanceolate-subulate, the fruit stalks 2 cm. Slender annual, once forked near middle, 35 cm tall; stem terete, purplish, glabrous; leaves 3-lobed, the leaves recurved; petioles 5 to 10 mm. long, smooth or thinly lanceolate above, the rachules 2 to 4 mm. long; lateral leaflets subsessile, elliptic-ovate, 3.5 to 6 mm. long, 1.G to 2 mm., broad, oblique at the base, obliquely emarginate at the apex, thick, smooth, pale beneath; terminal leaf narrowly elliptic-lanceolate, 12 to 23 mm. broad, obscurely cordate at the base, emarglnat at the apex, the spreading pllose petiole 0.6 mm. long; cymes short, bipartite, ca. 7-flowered; bracts subulate, 1.2 mm. long, sparsely ciliate with punctate glands, with 2 or 3 bristles at apex and a few loose foliose hairs at base; petals yellow, 6 mm. long; longer filaments placed dorsally, ciliolate above the appendage; styles 5, hairy;. long, widen at the angles. This new genus is difficult to assign satisfactorily among the subtribes of the Rutaceae, as the family is divided by Engler, but it clearly belongs to the tribe Xanthoxyleae and is probably a member of the subtribe Evodiinae. Big tree; branches reddish-strlgillose, glazed, grayish barked; leaves alternate, fairly close together, the leaves conical-obovate, 18 to 28 cm. In this group it refers to the Old World genus Melicope, which is tetrameric and differs in many other characters. Of the Decatropidinae, whither he proceeds. In Engler's key it differs by the lack of a gynophore and by its simple leaves, as well as by its united filaments. Pit Level Field Notes* In the dried plant they are a pale yellow white with a darker center. Arg*, but differs in the character of the stamens, which do not agree exactly with those of either section Peltandra or section Kirganelia. Twinning; stem slender, branched, pale with loosely pubescent hairs, glabrous; leaves alternate, trifoliolate; stipules subulate, herbaceous, deciduous, 2.5 to 4 mm. BLAKE—NEW PLANTS FEOM GUATEMALA AND HONDURAS, 13 especially along the veins, stout-reticulate; terminal leaflets oblanceolate or elliptic, acute at apex, acute at base, 5 to 8 cm. The flowers occur in the intermediate part of the panicle with all or nearly all the stamens failing^ a large HMobed disc and a definite rudiment of the ovary. This species belongs to the section AnAsophyllum, generally treated as a genus (Ghamaesyce) by American authors, although its structural characters are the least.

Solatium solitarium belongs in the group Lobanthes of the section Polymer, since the genus is arranged by Dunal in the Prodromus, It is distinguished by the character of its inflorescence and by its flowers. SCROPHULAEIACEAE, 23 and veins sparsely puberulous or short pilose, densely punctuated with appressed disc-shaped translucent glands; tendril when present simple, shorter than the leaves, pubescent like the leaves; flowers terminal, sessile, about 4-flowered panicles* pedicels 10 to 12 mm* long, densely puberulous, bearing deciduous umbels 2 minute above middle; calyx in buds ellipsoid-ovate, acute, campanulate at maturity, 10 to 13 mm long, membranous-herbaceous, densely glabrous-puberulent and sparsely punctate to ape-like with small, disc-shaped glands of pale yellow, divided into 2 short, 5 small teeth proper, more or less, irregularly connected in groups; crown 5 cm. In its densely dotted leaves, this species suggests the genus Stizophyllum, but has a different ash. It is closely related to Adcnocalymna flos-ardeae Pittier, of Panama, which has leaves similarly dotted but larger, more densely pubescent on the veins beneath, and a different arrangement of flowers. Shrubby vine; stem stout, sub-terete, glabrous, grayish bark; branches dark fuscous, subterete, striped, glabrous or very rarely with a few spreading hairs, thinly scaly-glandular; leaves opposite, conjugated, closed by a usually persistent tendril; stipules missing; petioles sturdy, 2.5 to 3.5 cm, long, subterete, spreadingly hairy, mainly on the upper side with dull hairs, and scaly-glandular, with age sometimes global; leaflets 2, the petioles resemble the petiole, 1.3 to 2.5 cm, long; leaflets usually suborbicular ovate, sometimes ovate, 7.5 to 13 cm. Shrubby vine; stem subterete, slender, gray-barked, glabrous; leaves opposite, conjugate, the tendril deciduous; stipules outdated; petioles cone-shaped, striped, densely gray-haired with spreading hairs, 2.5 to 2.8 cm. long; leaves 2, the petioles resemble the petiole, 1.5 cm. broad, short-acuminate, conically rounded at the base, chartaceous, above that deep green, somewhat shiny, finely hairy, mainly along the costa, very loosely reticulated with hardly any prominent veins, underneath dull green, evenly but not densely hairy with spreading whitish hairs, the whitish lateral veins about 6 pairs, prominent, the prominular secondary veins very loosely reticulated; tendril not seen; inflorescence of one or two approximately 8-flowered racemes ending in a lateral branch, the axis 1 to 1.5 cm, long, sparsely hairy, the persistent bracts subulate, about 1.5 mm. 10 mm* long; calyx bell-shaped, 15 to 19 mm, long, thin, tough, dark green, glabrous, half split at the bottom, with some saucer-shaped glands at the base; corolla yellow, drying black-green, 5*5 to 6 cm, long, thin-turkish, glabrous, the tube 1.5 cm, long, narrowed at the top, the funnel-shaped throat 3 to 3.5 cm. long, the limbs 1 to 1.5 cm, long, the 5 lobes depressed-orbicular, broadly rounded, flat; fertile stamens 4, glabrous, the. long, the highly divergent anther cells 3.5 mm. long, the slender staminode with lanceolate tip about 6 mm. disk thick, cupuliform, about 2 mm* high; pistil 4 cm, long; ovary thin ovoid, 5 mm. long, dense lepldote, compressed parallel to the partition, the eggs in about 6 pairs in each cell, certainly 1-row on each side of the placenta. NEW PLANTS FROM GUATEMALA AND HONDURAS* 25 Maefadyena guatemalensis is apparently the first true member of the genus reported from north of the Isthmus of Panama. BLAKE—NEW PLANTS FROM GUATEMALA AND HONDURAS* 25 Maefadyena guatemalensis appears to be the first true member 6t the genus reported from north of the Isthmus of Panama. It appears from description to be most closely related to M* mollia tSond.) Similar, but differs in its glabrous pedicels and corolla, and In several other characters. 1 cm, long, the flowers opposite at the nodes; bracts lance-subulate, attenuate from an ovate, sparsely ciliate base, 3 mm, long; bracts 2, similar but narrower and not dilated, slightly shorter; sepals 4, lance-linear-subulate, attenuate, sparsely cliolate or glabrous, 5.5 mm. This species is closely related to Dianthera breviflora (Nees) HemsL, which is described as having broader leaves with 8 or 9 parrs of lateral veins, rather dense subsessile vein, glabrous bracts, bracts and calyx, and smaller corollas, with the sepals ( 6 mm long) equivalent to the crown tube. Stapf writes that the type (Linden 184) of Rhytiglosm breviflora Nees, in the Kew Herbarium, has a corolla measuring 15 mm., to the apex of the ventral lip, 12 mm. BLAKE – NEW PLANTS FROM GUATEMALA AND HONDURAS* 27 This species belongs to the third group of the genus in the monograph of Cognlaux and is easily distinguished by its very small petals and their size. This new species is most closely related to Sclerocarpus major Small, which has papose achenes, rays with a lamina 1.8 to 2 cm. SufCrutescent or frescent, or sometimes herbaceous, erect or climbing, usually much branched, 0.6 to 1.3 meters high, from a tuberous thickened root 1 to 1.5 cm. Rich., but can be distinguished by its smaller heads with shorter obtuse leaves and pale leaflets. 31 (wing 1 mm wide), the wings united with the pappus, the narrower passing into a slender free canopy of 1 mm. This species is easily distinguished by its fine, hard hairs and by the shape of its leaves*. BartL It is distinguished from the former by its blunt phyllaria and dense subglandubir-pubescent stem; of the latter by the dense layer of glandular or subglandular hairs and by the absence of frizzy hair*.MEUACEAE
