Andrade-Lima (1953) also noted the high degree of similarity of this Bahian hylaea to that of the Amazonian terra firma and pointed to the role of high, annually well-distributed rainfall (2,000 mm. or more) in maintaining the two vegetation types. Vanzolini and Williams (1970) also have recorded the disjunct distribution in the At¬ lantic forest of “deep forest animals” from the Amazonian hylaea. The occurrence of Amazonian elements in these Atlantic forests, as well as in the central Brazilian cerrados and cerradaos and the northwestern caatinga, is a present-day indication of the previously more extensively distributed moist tropical vegetation and associated faunas that occurred as far south as central Patagonia in early Tertiary time (Menendez, 1969; Simpson, 1969). During the Eocene epoch tropical rainforest vegetation probably reached its maximum development, extending to at least 50° north and attained almost double its present distribution (Wolfe, 1971, pers. comm., 1972).

Miller Controversy over the taxonomic relationship of the Taxineae with the Coniferineae has created a new interest in the field of wood anatomy. This has been reflected by the flurry of investigations being conducted in families such as the Podocarpaceae. The systematic position of Amentotaxus is somewhat uncertain (see Keng, 1969). While many authors place Amentotaxus in the Taxaceae, this genus has also been referred to the Cephalotaxaceae or even con¬ sidered to represent a separate family, the Amentotaxaceae. When Kudo and Yamamoto (1931) described this last family, it was considered to be represented by only a single species, Amentotaxus argotaenia (Hance) Pilger. In his revision of Amentotaxus Li (1952) recognized four species. However, the description and publication of three new species of Amento¬ taxus based on leaf morphology would appear to have been overly opti¬ mistic and has not gone unchallenged. Hu (1964) recognized only three of the species, since she thought that Amentotaxus cathay ensis Li could not be usefully upheld as distinct. Moreover, Chuang and Hu (1963) con¬ sidered that Amentotaxus formosana Li was better referred to Amentotaxus argotaenia (Hance) Pilger. The divergence of opinion has increased the need to investigate any anatomical features that may be of taxonomic importance. In connection with this work it was thought an examination of the wood anatomy would be worthwhile, even though taxonomic eval¬ uation at the subgeneric level is not often successful in this field. A com¬ parative study of the wood anatomy within the genus Amentotaxus is considerably limited by the lack of availability of suitable material; most locations of Amentotaxus are in China. The scanty and now somewhat rare wood specimens were collected before 1935, with the exception of some from Taiwan. PRIOR INVESTIGATIONS Tang (1933) gave a short description of Amentotaxus argotaenia, based on two specimens from the province of Kwangtung in China. He noted rays 1-4 cells high in one specimen whereas in the other they were mostly 3-5 cells high. He also mentioned a slight difference in tracheid wall thickness between the early and late wood. A shorter description was made by Prince (1938). He stated in his introduction to the Taxineae that crassulae are clearly developed. Phillips’ (1948) brief description mentioned that the horizontal walls of the ray cells are relatively thick and sparsely pitted; and that the parenchyma cells are wider than the tracheids and have nodular end walls. PRESENT DESCRIPTIC ness is not significantly different in early and late wood and ranges from 2.5-5 /j.. 1973] MILLER, WOOD OF AMENTOTAXUS Figures 1-4, Amentotaxus ar go taenia. 1, Radial section showing horizontal spiral bands, X 280. 2, Radial section showing spiral bands up to 60°, X 280. 3, Radial section showing apertures perpendicular to spiral bands, X 1920. 4, Radial section showing apertures parallel to bands, X 2000.

This is because more bulky parts of plants are usually not trans¬ ported intact for great distances and thereby provide information on conditions at or close to the site of burial. In contrast pollen recovered from sediments may represent input from an area of substantial size and vegetational diversity. In upstate New York lateglacial forest vegetation has been broadly characterized by Cox (1959) who studied pollen succession at many sites in the region. Detailed pollen diagrams also are available from several locations at the west end of the state (Miller, 1973), but megafossils have not been used to complement these studies. The present report de¬ scribes the paleobotany and paleoecology of a lateglacial deposit in western New York. Included are pollen spectra and an account of abundant, well- preserved plant megafossils recovered from an organic bed. The mega¬ fossils comprise a fungus, oospores of four members of the Characeae, leafy gametophytes of thirty extant species of mosses, and represented by various kinds of remains, one vascular cryptogam, three conifers, and twenty-two flowering plants, nineteen of which have been identified to species. These data indicate the former presence of several distinct plant communities along the Lake Iroquois strand and suggest the likelihood of persistence of several of these plant assemblages at favorable sites in the region through postglacial time. GEOLOGICAL SETTING AND HISTORY The sediments described here are associated with Glacial Lake Iro¬ quois which occupied the Lake Ontario basin (Karrow et al., 1961) for about 2000 years between 12,600 and 10,500 years Before Present (B.P.). They are located in a gravel pit on the Leo S. Malloy property between Ewings Road and Eighteen Mile Creek, 4.5 miles north and a few degrees west of the center of the city of Lockport, Niagara County (43° 14' 16" N. Lat., 78° 42' 30" W. Long.). The organic bed originally was beneath about 3 meters of sand and gravel, but at the time samples were taken these sediments had been removed by quarrying. Richard L. McCarthy of Lockport, who made initial collections at the site, has obtained an age determination of 12,100 ± 100 B.P. (1-838, Buckley, et al., 1968) on a piece of spruce wood from the bed. I studied the pit three times between 1966 and 1969, and on my first visit (October 1966), the organic bed was just below the water table beneath about 5 cm. of clay and silt, the upper part of which was de¬ posited out of a shallow pond that covers the bottom of the excavation during wet periods. The bed was sampled again in December, 1969, through the ice, and exploratory digging both times showed the organic deposit to be of limited extent. The principal constituent of the deposit is wood. Large fragments of branches, stems, and roots are intermingled with abundant smaller woody debris 1 cm. or less in length, and very 125 ? !*! 126 JOURNAL OF THE ARNOLD ARBORETUM 1973] MILLER, LATEGLACIAL PLANTS JOURNAL OF ARNOLD ARBORETUM POLLEN SPECTRA, w.

Soil Development Statement of hypothesis. Whittaker (1970:69) stated: “A number of trends or progressive developments underlie most successional processes. There is usually progressive development of the soil, with increasing depth, increasing organic content, and increasing differentiation of layers or horizons toward the mature soil of the final community. . . Two points in this statement call for examination. First, the length of time involved in development, and second, the differentiation of soils into layers as they mature. Central to the argument is the idea that suc¬ cessive generations of plants leave their remains which are incorporated 342 JOURNAL OF THE ARNOLD ARBORETUM [vol. 54 I80C 1600 1400 1200 t 22 2408 £ '.8 23 V * 1 10 20 30 40 50 DIVERSITY = TOTAL NUMBER OF SPECIES mi JOURNAL OF THE ARNOLD ARBORETUM [VOL. 54 JOURNAL OF THE ARNOLD ARBORETUM sr: Table 3.

N. Mehra and T. S. Sareen The family Betulaceae includes six genera and over 100 species dis¬ tributed chiefly in the Northern Hemisphere. It contributes significantly to the forest economy of various countries of the world. Its most im¬ portant genus from the point of view of lumber is Bettda. Species of Alnus are exploited locally. Oil of birch is extracted from twigs of Betula lent a. Corylus aveUana is the source of European hazelnuts. Four genera with nine species are met in the Himalayas. Of these Betula cylindro- stackys and Corylus ferox are restricted to the Eastern Himalayas. Constituting the family Salicaceae are only two genera, Populus and Salix with 40 and 100 species respectively. Ranging between trees and shrubs (dioecious, rare individuals monoecious), they have almost world¬ wide representation, prevailingly in north temperate regions. The Indian members, roughly 30, are Himalayan with rare exceptions. Salix alone includes no less than 25 indigenous species. They are mostly water lov¬ ing and fast growing. A few of the willows serve for protection of river banks. Economic importance is attached to this group for ornamentals, in the manufacture of furniture, baskets, and bats, and for tannin, and balsam. Six species of this genus have been investigated. Material and Methods The material was obtained mostly from trees in nature in the Western Himalayas. Chromosome numbers were determined from squash prepara¬ tions of anthers fixed in Camoy’s fluid, and also from young leaves in one species, Carpinus viminea. Leaf-tips were pretreated with 0.003M so¬ lution of 8-hydroxyquinoline. Squashes of pollen mother cells and leaf- tips were accomplished in acetocarmine and acetolacmoid respectively. All figures are at a uniform magnification of X 1360. The voucher speci¬ mens have been deposited in the Panjab University Herbarium (India). Results and Discussion Cytological data of 12 species are summarized in Table 1. Meiosis was observed to be normal in all but two species. All taxa were characterized by small chromosomes.
