NOTESdark brown, striate. Leaves opposite, elliptic to lance-elliptic, denticulate withsmall, callose teeth, discolorous, the upper surface dark brown, glabrous orwith a scattered arachnoid tomentum, felted-lanate beneath, white to tan, pin-nately veined, lacking prominent lateral veins from the base; petioles ca. 1 cmlong, subterete, felted-lanate. Inflorescence paniculate, terminal and axillary.Heads narrowly campanulate, ca. 8 mm high; involucre imbricate, 4-5-seriate;phyllaries indurate, the outer ovate, obtuse, ca. 1 mm long, ciliate, the inner be-coming lanceolate, acuminate, ca. 5 mm long, mucronate; ray forets yellow,pistillate, fertile, the ligule 3-4 mm long, trifid, the style branches ca. 2.5 mmlong, slender, acuminate; disc florets yellow, funnelform, 5-6 mm long, thecorolla lobes 1-2 mm long, acute, the anthers exserted, the style branches ca.1 mm long, slender, acuminate. Achenes turbinate, ca. 10-ribbed, ca. 1 mm long,puberulent; carpopodium distinct, annular, light tan; pappus of both ray anddisc florets a single series of yellowish capillary bristles, persistent, ca. 5 mmlong. During the identification of various Panamanian Asteraceae, a collection ofLiabum hiattenuatum Rusby was discovered, a species previously known onlyfrom the Colombian Andes. This species is unique among the members of thisgenus in Panama in possessing leaves which are primarily pinnately veined andentirely lacking in prominent lateral veins arising from the base. This speciesmost closely resembles Liabum polyanthum Klatt; however, it is readily distin-guished from the latter by its smaller capitula and leaf venation. PANAMA.

NAMES IN AGALINIS FOR SOME PLANTS THAT WERE CALLED GERARDIA AND VIRGULARIA (SCROPHULARIACEAE) A New World group of plants with about 20 species in the eastern UnitedStates has, until recently, gone under the name Gerardia. The Montreal Code(Lanjouw et al., 1961) fixed the typification of Gerardia L. as applying to plantsin the Acanthaceae and rejected the name against Stenandrium Nees (Acantha-ceae). At the same time, Agalinis Raf. was conserved against Chytra Gaertner,making possible the substitution of the name Agalinis for the name Gerardia asformerly applied to plants in the Scrophulariaceae. This legislation was sub-ject to considerable controversy (Thieret, 1956; St. John, 1957; Wherry, 1957;DeWolf, 1957; Thieret, 1958; Morton, 1959). Ail the required combinations havebeen made for the North American species and several important floras havemade the substitution: Adams (1972); Correll & Johnston (1970); Radford et al.7691978]
