Fragments of Glaziou's eponymous type number (Glaziou 5918, from Corcovado, near Carioca Creek, Rio Janeiro, Brazil) are in the United States National Herbarium, obtained from the Paris Museum. Examination of the types of Baccharis ptarmicaefolia (Berlandier 572) and B. Mendez) shows that both are properly placed in the synonymy of B. Examination of the types in the Paris Herbarium, all of which are staminate, shows that all three are conspecific.

His specimen in the British Museum, labeled "Hort.", is of the actual species, as is the specimen of Xanthium fruticosum L f, in the Linnaean Herbarium. It is doubtful whether 7\ schiedeanum Less, is not a slender-footed form of the same species. A specimen of Galeotti 2468 (Oaxaca, altitude 1525 to 2135 meters), in the general collection of the Delessert Herbarium, belongs to the same species.
Examination of the type (Haenke, Acapulco) in the Prodromus Herbarium and of the best duplicate in the Schultz Bipontinus Herbarium, which is apparently the specimen mentioned by Bentham and Hooker, shows that Bentham's identification was incorrect and that Anaitis acapulcensis DC. Examination of the type, which is in very young flower, has shown its identity with Sigesbechia flosculosa. Examination of the type of Melampodium baranguillae Spreng., in the Schultz Bipontinus Herbarium, shows it to be identical with Sclerocarpus columbianus Rusby & Blake.
For now, the species can thus be recognized as separate on the basis of these characters of the fruit. The treatment in the first of these works M does not constitute publication of the genus or species under either the American or the international rules of nomenclature.

This consists of five specimens from Virlet d* A banishment collected at San Luis Potosi about 1851 and one collected by Karwinski at Tollman in 1827, accompanied by a note asserting its identity with Montagnaea frutescens DC. Montanoa wercklei Berger, described from specimens grown in Sir Thomas Hanbury's garden at La Mortola from Costa Rican seed obtained by Werckl6, is represented in the Kew Herbarium by three sheets from La Mortola collected in and 1912, It is merely a garden form of M.
Due to the relatively large flowers, the species was incorrectly associated with Montanoa grandifiora (DC.) in the original description. It is represented in the Schultz Bipontinus Herbarium by a flowering branch collected in the garden of Madrid in 1820, which corresponds perfectly to the brief description of Lagasca and which can be considered without doubt as authentic to the species. In both specimens the young pale specimens are ciliate underneath, subglabrous or glandular on the back, and provided with a rather abrupt, erect, spiny tip, exactly as in young pale specimens of Af.

Only the first two, in the order named, were mentioned by Koch in the description of the species. The species in the Prodromus Herbarium, collected by Haenke, was attributed to Mexico by DeCandolle, but doubtless came from Peru. Mexico, The species has only been found in Ecuador and Peru, and confusion in the labeling of Haenke's plants is well known.
An excellent but sterile specimen of the Martins plant is in the Prodromus herbarium and probably, on the basis of DeCandolle's description, is considered the actual type of the Martins species. SPECIMENS OF AMERICAN ASTERACEAE TYPE BLAKE 240 Euzenia radiata Nees & Mart., doubtfully transferred to Gymnopsis under a new name by DeCandolle from the original description, and omitted from Flora Brasiliensis, is represented in Schultz's Bipontinus Herbarium by an authentic specimen received from Nees and labeled "Brasilia Pr. The distinctive characters relied upon by Schulz to separate W* maculata are not apparent in the specimen of Nees and Martins' species, and the writer doubts whether he should refer to IF .
The type was described by Lindley from specimens grown in the garden of the Horticultural Society from seed from tierra fria of Mexico, presented by G. The type, Ehrenberg 346 in the Schultz Herbarium, from Mineral del Monte (=Real del Monte, Hidalgo), is identical with the type of Mr.

The type specimen of Heliantkus cornifolius in the Humboldt and Bonpland herbarium in Paris is in poor condition, but a better specimen from the same collection (Bonpland 4237) in the general herbarium in Paris shows that the species U is identical to the later Leighia urliciformis DC, if type has been examined in the Prodromus Herbarium. Juss./' has remained unidentified, It is represented in the Jussieu Herbarium at Paris by an excellent specimen (No. 9443) labeled. There is also a sheet of the same species in the general collection of the Paris Herbarium labeled “Helianthus canescens Vahl mss.

The identity of Zexmenia serrata Llave, the type species of the genus, has never been determined. One is Zexmenia scandens HemsL, and has two labels—. in an entirely different handwriting from that on sheet Z. In view of the definite label of the latter and its excellent agreement with the original description, there seems no reasonable ground for doubting that it is authentic to Llave's species, and that the identity of This, the type species of the genus Zexmeniar has finally been ascertained.
DeCandolle's type of this species matches Lamb 519, from Acaponeta, Tepic, but has even shorter pedicels (mostly 1*5 to 5 mm, long). In fragments obtained from Hemslcy's type Z> microcephala the squamellae are not absent, as described by Hemsley and W. Schultz's type, a specimen collected by Haenke in Mexico without a particular locality is available for study by the kindness of Prof-H.
Hill, the excellent specimen in the Kew Herbarium was loaned to the writer for examination some time ago. It is found to be identical with Verbesina egger&ii Hieron., based on Eggers 14941 from Hacienda El Recreo, Province Manabi, Ecuador (fragments of type in U. S. National Herbarium), Eggers 15687.
Robinson and Greenman,81 doubtfully listed it in their revision of the genus/F. In their revision of the Central American species of Calea, Robinson and Greenman 05 doubtfully placed Calea liebmannii in the Calydermos group on the basis of Klatt's inadequate and in some respects incorrect description, so the present writer abandoned it at C time. Remains of the same plant, apparently from Willdenow's herbarium, were examined by the writer in Schultz's bipontinus herbarium.
It is not one of the Mexican species, but agrees entirely, in material, with the plant recently described by the writer as Calea brevipes from the Department of Toll ma, Colombia (Pennell 3463, type). There is also on the sheet a single leaf of the same plant, labeled Ehrenberg 319, with the same locality as the others, and in addition a pocket of fragments from Willdenow's herbarium (no* 15301), with an unpublished name that he is not necessary to quote. The writer is unable to solve the problem presented by the attribution to both Aschenborn and Ehrenberg of the same number to the same plants, but it is nevertheless certain that this material may be taken as authentic, agreeing closely, as it is. with Schauer's description.
A brief statement of the identity of Aschenbornia heteropoda, without question, was given by the writer in Standley's additions". In 1925, the material in the Schultz Herbarium {Liebmann 558 and 693, and Galeotti 2472) and the type of T. , brachylepis (Galeotti 2024) at Kew were examined and a photograph of the first and last specimens referred to in the Schultz Herbarium and small fragments from the type 7\ brachylepis was obtained.

BLAKE-TYPE SPECIMENS OF AMERICAN ASTERACEAE 261 Schultz's name and unpublished diagnosis were apparently based on the Ehrenberg plant; which has a pappus considerably longer than the achene, the name as first published with description by Klatt refers to Liebrnann 598, with pappus shorter than the achene, and identification of the species must rest on this collection. As suggested by Robinson and Greenman/ the plant is a Calea and not a Tridax, and appears to be identical to Calea sabazioides (Less*) Hemsl., as Nelson 3232, from near San Cristobal, Chiapas (XL S. Nat. Herb .) is rightly referred to that still doubtful species, the type of which has not been critically examined by any author since its description.
Study of the best material of the type collection (Ekrenberg 355) in the Schultz Bipontinus Herbarium shows that this course was incorrect. The synonyms of Per soon and DeCandolle are omitted in Robinson and Greenman*s revision of Tridax*7 No authentic material of Persoon*s species, collected by Richard in Santa Marta, Colombia, has been examined, but specimens from the same locality labeled thus, collected by Bertero, introduced by Balbis and preserved in the Prodromus Herbarium as well as in the Schultz Bipontinus Herbarium are normal Tridax procunibenz L. The identity of all these specific names has long been known, but the preoccupation with the name Chrysopsis scabra has passed.
This Colombian and Venezuelan species appears different from the forms found from Ecuador to Bolivia and Peru.
