Jacquemontia sandwicensis A. Gray (Convolvulaceae) is an endemic, coastal species that has potential use for hanging baskets in Hawaii. Morphological variation exists in the wild, but efforts to collect, characterize and identify selections for hanging baskets have not yet been conducted. The objectives of this study were to: (1) characterize six accessions collected from Maui (Ahihi-Kinau, McGregor and Puhala Bay), Oahu (Lyon Arboretum and Shidler College) and Hawaii (South Point) islands and (2) identify accessions suitable for hanging basket use. Six plants from each accession were propagated and allowed to grow for 3 months under irrigated outdoor conditions. To encourage lateral branching, stems were pruned 10 cm from the base. After another month, 18 morphological traits were recorded and analyzed using ANOVA, principal component analysis and cluster analysis. Five qualitative characters were identified as useful for differentiating the six accessions. Significant differences between accessions were observed in eight quantitative characters. Nine morphological characters significantly contributed to the variation between accessions. Cluster analysis divided the accessions into three groups [Ahihi-Kinau, Shidler College and Lyon Arboretum (Cluster 1); Puhala Bay (Cluster 2); South Point and McGregor (Cluster 3)]. Length of internodes as well as number of lateral branches were the most important selection traits for hanging baskets. These helped identify Puhala Bay, Lyon Arboretum and South Point as potential accessions for hanging baskets.

Jacquemontia sandwicensisA. Gray（旋花科）是一种特有的沿海物种，在夏威夷有潜在的吊篮用途。野外存在形态变异，但尚未进行收集，表征和识别吊篮选择的工作。这项研究的目的是：（1）表征从毛伊岛（Ahihi-Kinau，McGregor和Puhala湾），瓦胡岛（里昂植物园和席德勒学院）和夏威夷（南点）岛屿收集的六种入藏物，以及（2）确定合适的入藏物用于挂篮。每种栽培种的六株植物繁殖并在室外灌溉条件下生长3个月。为了鼓励侧向分枝，将茎从基部修剪10厘米。再过一个月，记录了18个形态特征，并使用ANOVA，主成分分析和聚类分析进行了分析。鉴定出五个定性特征可用于区分六个种质。在八个定量特征中观察到了种质之间的显着差异。九个形态特征显着促进了种质间的差异。聚类分析将种质分为三类[Ahihi-Kinau，Shidler College和里昂植物园（第1组）； A。普哈拉湾（第2组）; 南角和麦格雷戈（第3组）]。节间的长度以及侧枝的数量是吊篮最重要的选择特征。这些帮助确定了Puhala湾，里昂植物园和南角市是吊篮的潜在材料。在八个定量特征中观察到了种质之间的显着差异。九个形态特征显着促进了种质间的差异。聚类分析将种质分为三类[Ahihi-Kinau，Shidler College和里昂植物园（第1组）； A。普哈拉湾（2类）; 南角和麦格雷戈（第3组）]。节间的长度以及侧枝的数量是吊篮最重要的选择特征。这些帮助确定了Puhala湾，里昂植物园和南角市是吊篮的潜在材料。在八个定量特征中观察到了种质之间的显着差异。九个形态特征显着促进了种质间的差异。聚类分析将种质分为三类[Ahihi-Kinau，Shidler College和里昂植物园（第1组）； A。普哈拉湾（2类）; 南角和麦格雷戈（第3组）]。节间的长度以及侧枝的数量是吊篮最重要的选择特征。这些帮助确定了Puhala湾，里昂植物园和南角市是吊篮的潜在材料。南角和麦格雷戈（第3组）]。节间的长度以及侧枝的数量是吊篮最重要的选择特征。这些帮助确定了Puhala湾，里昂植物园和南角市是吊篮的潜在材料。南角和麦格雷戈（第3组）]。节间的长度以及侧枝的数量是吊篮最重要的选择特征。这些帮助确定了Puhala湾，里昂植物园和南角市是吊篮的潜在材料。
