ResumoThe Raymond E. Hatcher collections of Hepaticae and Anthocerotae (413 specimens) are reported from the following areas in the Magellanian region of Chile: 1) a deciduous Nothofagus forest, 2) an ecotonal area between evergreen and deciduous forests, and 3) an evergreen Nothofagus forest. Several new southern range extensions are discussed. Cephaloziella gemmata Engel is described as new and Leptophyllopsis irregularis (Steph.) Engel is a new combination. The Hepaticae of southern South America are rather poorly known. Within the last decade several monographic treatments have resolved many of the taxonomic problems of the flora, but very little is known of the phytogeography and ecology of the taxa. Our knowledge, however, becomes considerably enhanced as rather large and reasonably thorough collections from critical localities become available for study. The collection of 413 Chilean Hepaticae and Anthocerotae by the late Dr. Raymond E. Hatcher (see Fulford & Whitford, 1968) has made such a contribution. The collection consists of 72 species in 39 genera. The southern Chile collections of Hatcher were obtained from the following critical areas: 1) in the deciduous Nothofagus forests near the Patagonian Steppe boundary (near Rio Rubens), 2) in or near an ecotonal area between evergreen and deciduous Nothofagus forests (Fuerte Bulnes region), and 3) in an evergreen Nothofagus (N. betuloides) -Drimys forest rather near the deciduous forest boundary (Cabo Leon). Figure 18 illustrates the vegetation of southern South America with the position of the collection localities indicated. While in Chile, Hatcher was accompanied by Dr. Margaret Fulford and the two were joined by Dr. Gabriella Hiissel de Menendez in Punta Arenas on or about 3 February 1962. On 4 February 1962, the party traveled to Fuerte Bulnes, stopping at Rio Blanco enroute, and then made about a 5-day (ca. 6-10 February) trip by car to Cerro Guido, a sheep farm north of Natales, but collected mostly near Rio Rubens.

Whitford of the University of Wisconsin-Milwaukee for facilitating the loan of specimens, Mrs. Evelyn Peters for curatorial help and typing the manuscript, and Richard C. Harris for assistance with the Latin diagnosis. The following groups were determined by other individuals, and their assistance is acknowledged with thanks. Dr. R. Grolle determined the specimen of Jamesoniella, Dr. G. Hdissel de Menendez the specimens of Riccardia, Dr. H. Inoue the specimens of Plagiochila, and the late Dr. J. Proskauer the specimens of Anthoceros and Megaceros. 2 Donald Richards Assistant Curator of Bryology, Department of Botany, Field Museum of Natural History, Roosevelt Road at Lake Shore Drive, Chicago, Illinois 60605.

HATCHER HEPATICAE AND ANTHOCEROTAE 529 Natales, ca. 100 km north of the Straits may have been gathered at Hotel Tres Pasos, as Dr. Hissel de Menendez states [in litt.] that the group stopped here but collected very little because of very dry conditions.) After returning to Punta Arenas the party went to Rio Verde where they were to depart by cutter for Cabo Leon on Seno Skyring, but inclement weather forced them to spend 14-15 February in Rio Verde. The group spent 17-18 February at Cabo Leon, where Hatcher collected in the interior portion of a river valley. After this portion of the expedition, Hdissel de Menendez left the party and Hatcher and Fulford traveled to Varas, Chile. However, it is doubtful if Hatcher collected bryophytes at Varas for there were no collections from this locality on deposit at the University of Wisconsin-Milwaukee. It is likely that Fulford made the collections at this locality while accompanied by Hatcher as Fulford (1963, p. 56) cited for the type of Temnoma chilense Fulf., Puerto Varas, R. Hatcher & Fulford (type Hb. Fulford, isotype Hb. Hatcher). Hatcher subsequently left Chile for Brazil, where he was joined by Drs. K. Hell and D. Vital. The Magellanian collections were gathered at the stations listed below. Each station will subsequently be referred to by the locality abbreviation (FB, RR, or CL-See below). The collection numbers listed below were used by Hatcher in the field as bag (and not individual collection) numbers, which were later penciled onto the face of each packet. During my study of the collections, I grouped specimens of like bag number and provided individual specimens with a number which I appended to the bag number by a hyphen. There were a few to many specimens enclosed in each bag and only upon one occasion was there a single specimen in a bag. Each bag then, has its own numbering series, hence Hatcher 1-6 indicates bag one, specimen six. The dates listed with the abbreviations are those found on a typed sheet of collection data in the Hatcher files. Hatcher also used these dates on the labels. FB-Hatcher 1-10. 53037'S, 70056'W. PROv.

A complete set of the collections will be deposited in the herbarium of the University of Wisconsin-Milwaukee (uwM). The Hatcher collection contains two new species-Cephaloziella gemmata Engel and Marsupidium flavicans Engel & Grolle (described in Engel & Grolle, 1971)several noteworthy range extensions, and several rare, poorly known species. The determinations, with the exception of a few genera, are my own. Adelanthus lindenbergianus (Lehm.) Mitt. FB: 2-4, 4-11, 7-13; CL: 18-1, 19-3, 20-1, 24-5, 33-4, 40-1, 41-6, 48-3. Anthoceros punctatus L. FB: 10-1.-This widespread taxon occurs, according to Hissel de Menendez (1962), in southern South America, North America, Europe, and Asia. In southern South America the species was previously known only from eastern Patagonia (Prov. Misiones and Prov. Buenos Aires). The Hooker collection(s) of A. punctatus from Isla Hermite, at least in the Taylor Herbarium (Farlow Herbarium), are misdeterminations of Megaceros endivaefolius, as pointed out by Evans (1898). Apometzgeria frontipilis (Lindb.) Kuw. & Engel. CL: 22-1, 61-6. Apometzgeria pubescens (Schrank) Kuw. FB: 2-6.-This Hatcher collection formed the basis for the first authentic report of the taxon from the southern hemisphere, with the species This content downloaded from 157.55.39.116 on Sat, 11 Jun 2016 04:55:26 UTC All use subject to http://about.jstor.org/terms 530 THE BRYOLOGIST [Volume 76
