Although dissimilarities in cranial and post-cranial morphology among African pygmies groups have been recognized, comparative studies on skull morphology usually pull all pygmies together assuming that morphological characters are similar among them and different with respect to other populations.
To a large extent, many of the families in Asparagales are defined primarily by DNA characters, and unique morphological characters are not obvious within families.
All measurements of morphological characters are summarized in Table 2.
The morphological characters are related to their crystal structure and growth mechanism.
Its morphological characters are remarkably different from those of other cultivars or species.
Because morphological characters are of limited use, studies have mainly focused on new taxonomy methods, i.e., chemotaxonomy.
In the marine brown macroalgae, the morphological characters are highly similar between two widely distributed genera, Homoeostrichus and Zonaria (Dictyotaceae), thereby resulting in the difficulty of exploring their hidden biodiversity.
In fact, it is a useful tool for the identification of cryptic species, particularly when diagnostic morphological characters are lacking or are difficult to analyze (Kim et al., 2010a; Sherwood, 2008).
The most characteristic feature of Actephila alanbakeri are its knobbly fruits, but other diagnostic morphological characters are discussed and information about its ecology and rhizosphere and plant tissue chemistry is provided.
Rather, it has close affinity with the hypogeous (below the soil surface) genera of the Morchellaceae, including Fischerula, Imaia, and Leucangium, but both genetic and morphological characters are sufficiently distinct to warrant designation as a distinct genus.
In this group, taxonomically useful morphological characters are few.
