In the context of morphologybased taxonomy, phylogenetic analysis of morphological data is also critical for placing new species within a higher taxon, given the obvious shortcomings of using overall morphological similarity to classify species eG, wiley,Get Price
It is the prime importance to know exactly to which species a plant specimen belongs this is necessary for a natural and reliable classification most of the plants are classified according to their macromorphological features but an accurate classification results when theGet Price
Jul , with these images, we will be able to collectively build largescale morphological datasets, but these will only be useful if the limits to this approach are wellknown to establish these limits, we used twodimensional images of plant specimens to test the precision and accuracy of imagebased data and analysesGet Price

Plant parts that are too large for a single sheet may be cut into sections pressed on a series of sheets, for example a palm or cycad frond long and narrow specimens such as grasses and sedges can be folded once, twice or even three times at the time of pressing in this way a plant of up to metres high may be pressed onto a single sheetGet Price
Plant specimens were identified by using the flora, morphological analysis was carried out by using observation and measuring techniques the observation of the study revealed that certain qualitative characters have similarity among five selected species of ipomoea and some other character shows variation from species to species and accessionsGet Price
