Perennation Hypothesis In support of the hypothesis (Fig. 20), only the experimentally amputated Curlew Cay morphs (both f. longicaulis and f. asarifolia) showed significantly more proliferations (100 %) than either the experimentally amputated Twin Cays morphs (both f. laxa and f. olivacea) or the uncut Curlew or Twin Cays control plants. In particular, the amputated Curlew Cay Avrainvillea longicaulis f. longicaulis showed 100 % new proliferations, a significant fivefold increase relative to the Twin Cays f. laxa (20 %). The uncut controls from Curlew Cay f. longicaulis showed significantly fewer (70 %) new proliferations, whereas the Twin Cays experimental f. laxa plants also had significantly fewer (50 %) new proliferations. In the case of Avrainvillea asarifolia f. asarifolia from Curlew Cay (Fig. 20), the experimentally amputated plants also had 100 % new proliferations paralleling the results for A. longicaulis f. longicaulis. The experimentally amputated f. olivacea also showed significantly fewer proliferations comparable to those for f. laxa (only 20 % new proliferations, significantly less at P < ). The uncut control morphs of A. asarifolia from both Curlew Cay (f. asarifolia) and Twin Cays (f. olivacea) produced comparably low results as well, with significantly fewer (40 %) new proliferations (Fig. 20)..
