DENOTATA OCCIDENTALIS F. FOSTERI F, HUBRICHTI Figure 21. Distribution of Triodopsis obstrica and losteri, and the geographic variation of the character index in ob- stricta. Thick, solid line surrounds the range of o. obstr/cfo, o. denofoto, and hybrids between the two subspecies; thick, dashed line, those peripheral areas of the range where limited interbreeding took place; dotted line surrounds the range of foster/. Question mark beside a symbol means uncertain locality record. C, type locality of caro//n/ens/s, considered hybrid o. obsfricfo X o. denotata; HE., helicoides, considered synonymous with o. obsfricto; OBS., o. ob- stricta; OCC, occidentalis, considered synonymous with Mesodon sorgent/onus; FO., f. foster/; HU., f. hubrichti; Ml., m/ssour/ens/s, considered synonymous with I. foster/'. Numbers without a circle are mean values of samples in character index; the samples of o. denotata range from 0 to 25, hybrid 40-75, o. obstricta, 80-100. Other symbols refer to ele- vation, forest types, and state boundaries, as explained in Figure Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Harvard University.
