Jensen, to deal with variability within ind{\textquoteright}ls, has in previous studies relied on (1) foliage exposed to full sunlight and (2) intraindividual averages. Few studies have examined intraindividual patterns of variation. Questions driving the study: Can variation in lf morphology distinguish (1) ind{\textquoteright}ls within a population, (2) taxa within a community, and (3) hybrids from pure individuals. ALSO, (4) is Q. ellipsoidalis a taxon of hybrid origin Methods MLDA (multiple linear discriminant analysis) on 9 lf variables. MLDA differentiates groups by comparing within and among group variances. If w/in tree variation < among-tree variation, then linear discriminant functions should be useful in recognizing trees. Findings 1. Lvs are correctly assigned to their respective trees > 75\% of the time for 18 of 19 populations (N = 7{\textendash}21 trees / pop{\textquoteright}n) 2. Hybridization lowers correct classification rate, b/c hybridization increases within-tree variance. 3. The poorest class{\textquoteright}n rate (45.8\% success) represents type specimens of Q. ellipsoidalis collected by E.J. Hill and Agnes Chase {\textendash} Jensen{\textquoteright}s population 19. My concern (10-26-2006) Looking at Jensen{\textquoteright}s lectotypification article (Jensen 1979), it appears that he analyzed 12 sheets representing 3 trees: 10 sheets of Hill 176, 1895 (collected in different years); 1 sheet of Hill 95, 1896; and 1 sheet of Hill 96, 1896. If so, is the poor classfication rate due to the fact that the within group and among group variances are nearly the same?},

	abstract = {Vegetative characters have been considered unreliable for distinguishing oak taxa. Results of a series of multiple linear discriminant analyses of collections containing 1 or more oak taxa are presented. Leaf characters not only can separate the various taxa, but in the absence of hybridization, each tree in each collection may be recognized as a distinct multivariate entity. Comparison of an analysis of the type materials of Q. ellipsoidalis with the results of other analyses supports the hypothesis that the type population of this species was a hybrid swarm.},

	abstract = {Leaf herbivores potentially reduce plant fitness by increasing fruit abortion. The impact of leaf herbivory on fruit abortion, however, may vary with branch height in trees because of differential investment in reproduction among branches, differences among branches in exposure to solar radiation and the mobility of resource movement among branches following defoliation. Here we describe spatial patterns in abundance of lepidopteran herbivores and resultant damage in the canopy of mature white oak trees, Quercus alba. The effect of foliar damage on fruit abortion for upper and lower canopy branches was also examined. A significant positive correlation occurred between foliar damage and spring herbivore abundance. Damage measured at the end of the season was unevenly distributed throughout the canopy, varying from 10-20\% leaf area loss. A significant positive correlation between percent herbivore damage and percent fruit abortion also existed. Moreover, upper canopy branches had a higher percentage of fruit abortion for a given damage level than lower canopy branches, even though herbivore damage did not differ significantly with canopy height. These results suggest that early season leaf-chewing herbivores negatively affected fruit production, but the impact on fruit abortion depended upon the location of the damaged branch. Resources apparently did not move from lesser-damaged branches to more heavily damaged branches to reduce reproductive losses.},
