Among them eight species are described as new to science and twospecies are recorded for the first time in this country. Type specimens except otherwise no-ted are kept in the Biology Department of Nankai University,Lygus (Apolygus) hilaris (Horvath) New record from China: Zhejiang.     

POSITIONAL AND SEASONAL VARIATION IN OAK (QUERCUS; FAGACEAE) LEAF MORPHOLOGY

Within-tree and seasonal variation in quantitative characters of oak leaves were evaluated by factorial analysis of variance. All linear and areal measurements illustrate marked within-tree and seasonal variation. Numbers of lobes and bristle tips and primary vein angle appear relatively stable within trees and among seasons. In many instances, size-correction reduces both within-tree and seasonal variance to nonsignificant levels. However, all characters do not illustrate the same trends either within trees or across the seasons. The results have important implications for those attempting to evaluate among-tree and among-population variation.

CHROMOSOME RELATIONSHIPS OF DIPLOID SPECIES OF GRINDELIA (COMPOSITAE) FROM COLORADO,NEW MEXICO,AND ADJACENT AREAS

Previous studies of chromosome relationships of Grindelia species recognized three basic genomes designated Oxylepis, Hallii, and Havardii. Differences are based on different end arrangements of the chromosomes resulting from reciprocal translocations. This report will review and give additional information about the genomes and interrelationships of 17 species. All of the species are diploids (2n = 12) and show six bivalents at meiosis. Species in this study that have the Oxylepis genome are G. oxylepis var. eligulata, G. fastigiata, G. inornata, G. revoluta, and G. squarrosa. Species that have the Havardii genome included G. havardii, G. grandiflora, G. lanceolata, G. littoralis, and G. texana. The Hallii genome is present in G. camporum var. davyi and G. procera. Hybrids of species with the same genome have six bivalents at meiosis. Hybrids between species with the Oxylepis genome and those having the Havardii genome have four bivalents and one quadrivalent at meiosis. Likewise for Oxylepis x Hallii hybrids. A new genome is presented for G. subalpina which would explain the configurations of two bivalents and two quadrivalents observed in G. subalpina x G. havardii and G. subalpina x G. fastigiata hybrids. This is designated the Subalpina genome. Species tested but with genomes as yet undetermined are G. acutifolia, G. arizonica, G. nana, and G. scabra.
