摘要

摘要形态计量学数据用于研究莎草和相关的亲花岗岩类之间的关系，特别是最近从德克萨斯州和俄克拉荷马州的花岗岩露头中报道的亲花岗岩种群。使用主成分分析（PCA）、判别分析（DA）、多变量方差分析（MANOVA）和欧氏距离树状图分析了406份凭证样本中23个字符（变量）的数据。结果（1）强烈支持将C.grantisophilus和C.squarosus作为单独的物种处理，但（2）为正式承认C.squarousvar.runyonii提供了充其量是微弱的证据，以及（3）表明最近被报道为C.grantisiphilus的得克萨斯州和俄克拉荷马州种群与C.squarous的亲缘关系比C.grantistophilus更密切。

A Morphometric Analysis of the Cyperus squarrosus-Cyperus granitophilus Complex in North America, with the Description of a New Variety of Cyperus squarrosus

ABSTRACT Morphometric data were used to investigate the relationship between Cyperus squarrosus and related C. granitophilus, with particular attention to populations of C. granitophilus recently reported from granite outcrops in Texas and Oklahoma. Data for 23 characters (variables) taken from 406 voucher specimens were analyzed using principal component analysis (PCA), discriminate analysis (DA), multivariate analysis of variance (MANOVA), and a Euclidian distance dendrogram. Results (1) strongly support the treatment of C. granitophilus and C. squarrosus as separate species but (2) provide at best weak evidence for formal recognition of C. squarrosus var. runyonii and (3) indicate that the Texas and Oklahoma populations recently reported as C. granitophilus are more closely related to C. squarrosus than C. granitophilus.

期刊介绍： Castanea is named in honor of the American Chestnut tree. Castanea is thebotanical name for Chestnuts, dating back to what the ancient Greeks calledthem. The American Chestnut is a critically endangered tree that once made up 35%of the forests of the Eastern US before being devastated by a blight thatdestroyed up to 4 billion American Chestnut trees. Castanea serves professional and amateur botanists by reviewing andpublishing scientific papers related to botany in the Eastern United States. We accept papers relating to plant biology, biochemistry, ecology, floristics,physiology and systematics.
