To determine the size and the density of stomata among different environments, we conducted anatomical analyses using Aster hispidus var. hispidus (open field), As. hispidus var. leptocladus (serpentine soil), and As. hispidus var. insularis (coastal). The stomatal size was not significantly different among these ecotypes but the density of stomata in the serpentine and coastal ecotypes was significantly lower than that of As. hispidus var. hispidus, which suggests that these ecotypes have experienced selection that reduced the density of stomata for adaptation to the dry conditions of serpentine and coastal areas.

“…The serpentine ecotype of A. triphylla var. japonica also had narrow leaves, but the leaf thickness and stomatal density was significantly different from those of the normal plants, suggesting that there were different adaptation processes between the two ecotypes of this species [12]. From these studies, it appears that A. triphylla var.…”

The comparative morphology and anatomy of leaves between the coastal ecotype and the normal type of Adenophora triphylla (Thunb.) A.DC. var. japonica (Regel) H.Hara (Campanulaceae) were examined to clarify the differences in morphological characters between the 2 groups. Morphological and anatomical analyses revealed that the coastal ecotype had a thicker leaf than the normal type, because of the increased size of epidermal and spongy cells. Thus, the main morphological change from the normal type into the coastal ecotype of A. triphylla var. japonica is the increase in leaf size, suggesting that the coastal ecotype may have evolved from the normal type via a heterochronic process.

“…The origin or the introduction events of KP and WP are not found in published literature. In the present study, the species of WP and KP were confirmed as H. verticillata and A. triphylla, respectively (Ohga et al, 2012;USDA, 2018). It can be speculated that WP and KP were introduced to Sri Lanka from East Asia; however, further studies are needed for the confirmation.…”

Asiatic pennyworts (AP) (Centella asiatica) are among the most popular leafy vegetable species in Sri Lanka. Five AP cultivars, namely, Lowland AP (LAP), Giant AP1 (GAP1), Giant AP2 (GAP2), Salad AP (SAP), and Medicinal AP (MAP) are grown in the country. Two other leafy vegetable species, water pennyworts (WP) (Hydrocotyle verticillata) and Korean pennyworts (KP) (Adenophora triphylla), are also designated under 'pennyworts' in Sri Lanka. The consumerpreference on the pennywort bunches available in the market and the salad properties are yet to be studied. Also, no attempts have been reported for the identification of species delimits and phylogenetic relationships among the different cultivars of C. asiatica. In the present study, consumer preference on the appearance of leaf bunches and salads of pennyworts were assessed. The intra-and interspecific variation of pennyworts grown in Sri Lanka were also studied. The genomic DNA extracted from the immature leaves was PCR amplified for the DNA barcoding markers matK-trnT, atpB-rbcL, and rbcL. The PCR products were sequenced and used to assess the intraand interspecific variation. The consumers mostly preferred to purchase the leaf bunches of GAP2 because of its large leaf size and appealing look. However, the highest preference for salads was reported for the dishes prepared using LAP, MAP, and WP. The clade structure of the phylogenetic tree drawn for AP cultivars shows an intraspecific variation. Our study also highlights the importance of producing an improved AP cultivar with larger leaf size, improved flavor properties, and sinuate leaf margin.
