In this study naturally growing morphological variation of Lilium tsingtauense (Korean wheel lily), from southern Chung San Island to northern Mount Seorak, was investigated in 16 habitats around the country. Morphological analysis revealed that this species had its own unique characteristics in different habitats. Flowers with luster are in actinomorphic form, with shades of orange, each plant having an average of 2.4 flowers that blossom upward. The shape of flower petals was from oval to oblong. The width of the petals, which determines the shape of the flower, significantly varied among regions. Flower petals showed purple spots and its occurrence greatly varied among plants from almost none to 300 spots per flower. In addition, when the number of spots increased, the flower color was more vivid. Leaves were typically one-tiered verticillate and most of the leaves were long, oval and some were lanceolate. Young leaves showed definitive patterns that faded during growth. Starting from the verticillate leaves, stems below the leaves were smooth, although 81% of all stems, above the verticillate leaves, showed rough micro-protrusions. Bulb shapes were long and vertically elliptical. The ramentum was light yellow in color and the base was darker, with the color fading toward the upper region of the plant. The shape of the ramentum was long, with a pointy end, and its adhesiveness was weak. This study offers basic fundamental information for the effective exploitation and recognition of L. tsingtauense resources as a potential cut flower and potting plant in floral trade worldwide.

Southern Xinjiang

Rosa laxa is widely distributed in the Xinjiang Uygur Autonomous Region of China and is highly adaptable and rich in variation. In this study, we investigated the morphology, habitats, and palynomorphology of R. laxa botanical varieties from Xinjiang, China. In addition to R. laxa var. laxa, there were three other botanical varieties of R. laxa growing in southern Xinjiang, including var. mollis, var. kaschgarica, and var. tomurensis. Together, these four botanical varieties exhibited morphological variation, mainly in the morphology of prickles and the glandular trichome and in flower color. The pollen grains of the R. laxa botanical varieties, all medium in size (21.77–48.39 μm), came in three shapes: perprolate, prolate, and subspheroidal. Their pollen exine sculptures were characterized by either a striate-perforation pattern or striate pattern, but perforation varied in terms of diameter and density and striae varied in depth and density. Palynomorphological assessment showed that three types of evolution, i.e., primitive, transitive, and evolved, were present among R. laxa botanical varieties, and pollen dimorphism was observed in the same botanical variety. Perprolate pollen with a dense striate pattern was the most evolved type. Based on morphological and palynomorphological investigations, var. tomurensis was considered to be the most evolved one among the studied botanical varieties.

Morphological Variables

Pitted morningglory is an adaptable species with an indigenous range encompassing the southern Midwest and southeast United States. In 2000 through 2002, 64 pitted morningglory accessions from 11 states were grown in Fayetteville, AR, to compare their morphology in a common environment to document potential morphological variation and to determine whether variation proves the existence of pitted morningglory morphological ecotypes. Accessions were evaluated for leaf size and vine length 8 wk after emergence (WAE), date of flower initiation, flower color, leaf pubescence 12 WAE, capsule and sepal pubescence, sepal length and width, plant weight, and seed number at physiological maturity. Morphological variables were standardized and analyzed with cluster analysis to differentiate the morphological variation among accessions. Documented variation was best described by eight clusters. Four clusters distinguished themselves morphologically. Accessions within these distinct clusters were originally from Arkansas, Delaware, Kentucky, Louisiana, Mississippi, and Missouri and were documented with leaf size, vine length, and day of flower initiation generally increasing with decreasing latitude. The other four clusters were nondistinct because most variables differed very little, but characteristics such as capsule pubescence separated these clusters. Accessions within these nondistinct clusters originated from Arkansas, Georgia, Louisiana, North Carolina, Oklahoma, and Tennessee. Leaf shapes of arrow, heart, an arrow and heart mixture, and heart with pointed projections and white or purple flower colors were documented. Documented differences indicate the existence of pitted morningglory morphological ecotypes.
