\textbf{Abstract}
\begin{abstract}
\normalsize{
\textit{Cleome gynandra} (L.) Briq., commonly called spider plant or cat's whiskers, is among traditional African leafy vegetables with  increasing importance in many countries. \textit{C.~gynandra} shares the common name ``spider plant'' with Chlorophytum comosum, the latter being purely ornamental plant in Europe and America. Despite its importance, the crop has received little attention from various crop improvement programs. The objective of the current study was to assess morphological variations within and among 32 accessions based on 255 lines developed by single plant selection from the accessions grown in the same nursery in adjacent plots. The accessions were obtained from AVRDC --- The World Vegetable Center, Eastern and Southern Africa (AVRDC-ESA)'s collection from Malawi, Rwanda, South Africa, Tanzania and Uganda. The assessment was conducted in the field at AVRDC-ESA, \mbox{1290\,m}. asl, 3.4° S latitude and 36.8° E longitude, in Tanzania in 2014 and 2016 in an augmented design in five blocks with five advanced lines included as references. Both quantitative and qualitative data were collected. This paper presents results of the two years. Nei's phenotypic diversity index, hierarchical cluster analyses --- using the Nearest Neighbour Method --- and correlation coefficients among selected traits have been analyzed. Results on farmers' participatory line selection for marketability vegetative yield and other traits have been included. Preliminary analysis indicates that lines from the same accession did not necessarily cluster together. This could be partly because outcrossing might have taken place among accessions from which the lines developed were grown in adjacent plots. The finding on diversity available among the accessions for some of the traits is expected to guide follow"=up studies and be useful for use in breeding program.}
