Seventeen genera and 48 species, in five subtribes, are recognized in Thailand. These include 15 endemic taxa, half of which are in the largest genus, Acilepis, with others in the genera Camchaya, Koyamasia, and Okia. A new monotypic genus, Pulicarioidea, is established with P. annamica, the new name for the species formerly known as Vernonia pulicarioides. New combinations are also made for Acilepis kerrii, Cyanthillium montanum, Koyamasia curtisii and Okia pseudobirmanica. Forty-six characters including habit, leaf, flower, achene and pollen morphology were analyzed using UPGMA. Five clusters of taxa were identified. Keys to genera, species and varieties, descriptions, vernacular names, ecological data and illustrations are provided.

The Vernonieae have been shown to be unequivocally monophyletic and are well represented in both the Old and New Worlds, with centers of diversity in east Africa and Brazil (

The largest concentration of endemic Vernonieae is found in the northern and northeastern regions of Thailand, and outside of the country’s political boundaries in the adjacent regions of Burma and Yunnan, China. Taxa are typically found in open areas within dipterocarp, deciduous, evergreen and pine-oak forests, at elevations from sea level to over 2000 m. There are 15 endemics: Acilepis chiangdaoensis, Acilepis doichangensis, Acilepis kerrii, Acilepis namnaoensis, Acilepis ngaoensis, Acilepis principis, Acilepis pseudosutepensis, Acilepis sutepensis, Camchaya pentagona, Camchaya spinulifera, Camchaya tenuiflora, Camchaya thailandica, Koyamasia calcarea, Koyamasia curtisii var. tomentosa, and Okia pseudobirmanica (treated as species of Vernonia by
Koyama’s treatments were used as the starting points for this study, with modifications in generic assignment by
Herbarium specimens were obtained from AAU, B, BCU, BK, BKF, BM, C, E, G, K, KKU, L, P, PSU, QBG and US. Field collections were also made throughout Thailand by the first author and have been deposited at KKU, QBG and US. Information recorded from specimens included distribution, and when available ecological data and vernacular name(s). Only mature vegetative and reproductive parts were measured or scored. Macromorphological measurements, presence/absence and specifics of surfaces and vestitures were obtained by light microscope. Achenes, leaf surfaces and unacetolyzed pollen were observed with scanning electron microscopy (SEM) using a LEO, 1450VP. A complete listing of taxa and voucher information are given in Table 1.

Five clusters of taxa are recognized in the UPGMA analysis as shown in Fig. 4. These groups largely correspond to three Old World subtribes recognized by
UPGMA tree for 42 Thai Vernonieae based on vegetative, reproductive and pollen morphology (see Table 2, Figs 1, 2, 3). Number above the lines indicate bootstrap support (1000 replications). Zero length branches indicated by arrows.
Camchaya is a well-supported genus within the subtribe Centrapalinae (Fig. 4). It is characterized by an annual habit, erect, leafy stems, achenes without a carpopodium, a deciduous pappus, and echinolophate hexaporate pollen.
Structural features including pollen place the Asian Gymnanthemum and Decaneuropsis clearly in the subtribe Gymnantheminae, but DNA sequencing is still needed for confirmation. The place of Monosis is less certain. For example, genera such as Decaneuropsis (and possibly Strobocalyx and Tarlmounia) have been assigned to the Gymnantheminae (i.e.
A similar situation also appears to exist in the subtribe Erlangeinae which, like the Gymnantheminae and Centrapalinae, is primarily African (
Unlike the Centrapalinae, Erlangeinae, and Gymnantheminae described above, however, the membership of taxa in the Elephantopinae is clear (Fig. 4). Additionally, this subtribe has been previously shown to be monophyletic using DNA sequence data (
There is now a taxonomic framework that will allow for future development of and testing of hypotheses of Vernonieae relationships over a wide region of the Old World including Africa and south and southeast Asia. Of particular interest are the relationships of taxa now putatively in the same subtribe but whose characteristics differ (i.e., between Asia and Africa). Thailand may also be key to understanding subtribal radiations across the Old World as it is located at the crossroads of biotic migrations westward from Malaysia and eastward from India and Africa. Understanding the subtribal histories will allow us to follow the historical pathways of dispersal, and identify habitat types that promote endemism and local adaptive radiations. The Vernonieae has been referred to as the “evil tribe” (
A key to the genera and species within each genus is provided below. Subtribes are shown in Fig. 4. It is hoped that the reader will use this to gain greater understanding of the tribe in Thailand, and that it will spur further work on this beautiful and challenging group.
