Abstract

This is a morphological study of 108 accessions of Solanum campylacanthum and 10 accessions of Solanum cerasiferum. The aim was to assess the morphological variations that occur within the S. campylacanthum species in Uganda and evaluate the morphological differences between S. campylacanthum and S. cerasiferum. Fourteen quantitative and eleven qualitative vegetative characters were measured and analysis done by phenetics method. Cluster (UPGMA) and box plot analyses were done in PAST program version 4.03. Prickle density and leaf tip angles are reported for the first time as being useful in the intraspecific delimitation of S. campylacanthum. The distinction between S. cerasiferum and S. campylacanthum can only be based on leaf base shapes, which is, attenuate and oblique respectively.

乌干达茄科植物 Solanum campylacanthum 的形态变异及其与 S. cerasiferum 的关系

这是一项形态学研究，研究对象是 108 个 Campylacanthum Solanum 和 10 个 cerasiferum Solanum。目的是评估乌干达 S. campylacanthum 品种内部的形态变异，并评估 S. campylacanthum 和 S. cerasiferum 之间的形态差异。研究人员测量了 14 个定量植被特征和 11 个定性植被特征，并采用表观遗传学方法进行了分析。聚类（UPGMA）和箱形图分析由 PAST 程序 4.03 版完成。首次报告了刺密度和叶尖角在 S. campylacanthum 的种内划分中的作用。S. cerasiferum 和 S. campylacanthum 之间的区别只能基于叶基部的形状，即分别是渐狭型和偏斜型。

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
