FIGURE 15 in Seven new species of Trichostema (Lamiaceae: Ajugoideae) from the North American Coastal Plain biodiversity hotspot
FIGURE 15. Approximate known range of Trichostema bridgesii-orzellii based on field data and herbarium records (solid line). The northern and western extent of this species is unknown due to extensive habitat loss and limited sampling, but given biogeographic patterns in other organisms, it is likely restricted to the Lake Wales Ridge (hashed line).

Data from: Karyotype and genome size variation in genus Ajuga L. (Ajugoideae–Lamiaceae)
Chromosome number changes and karyotype evolution play an important role in plant genome diversification and eventually in speciation. The genus Ajuga L. (Lamiaceae) has approximately 50 species distributed in temperate to subtropical regions. Four of these species are currently recognized in Korea (A. decumbens Thunb., A. multiflora Bunge, A. nipponensis Makino and A. spectabilis Nakai). Understanding the karyotype evolution in Ajuga has been hampered by the small size of their chromosomes and symmetrical karyotypes. Here we used classic Feulgen staining to establish chromosome numbers and construct karyotypes of the four species of Ajuga recognized in Korea and flow cytometry was used to study their variation in genome. The chromosome number of all investigated plants was 2n = 32. Still, the 2C DNA content ranged from 2.18 pg (A. decumbens) to 4.53 pg (A. multiflora). While the chromosome numbers were the same for all investigated species, the genome size variation could potentially be used as a taxonomic marker.
