Drought tolerance limits are given for 36 new 'resurrection plants', sufficient to double the number of desiccation tolerant plants reported from southern Africa. Tolerance limits for angiosperm examples are usually better than those for ferns. Air-dry foliage survives for 1/2 to 5 years or more, unless stored in humidities above 50% RH Abbreviation: RH = relative humidity . Dehydration is sufficiently slow (usually 2-3 days) to allow the possibility of a tolerance induction process, like that found in Borya nitida. Rehydration after rain is usually complete in 1/2 to 1 day. A significant proportion of rain is absorbed through the leaf surface, but there is no evidence of appreciable rehydration from dew.Resurrection plants are usually pioneers in xeroseres, but they often lack xeromorphic characteristics. Anthocyanin pigmentation during drying is a reliable indicator of viability in some species.
给出了36种新“复苏植物”的耐旱极限，这足以使报道的来自南部非洲的耐干燥植物数量翻倍。被子植物样本的耐受极限通常优于蕨类植物。风干的叶子能存活半年至5年或更长时间，除非储存在相对湿度高于50%的环境中（缩写：RH = 相对湿度）。脱水足够缓慢（通常为2 - 3天），使得像在亮叶波瑞亚中发现的那种耐受诱导过程成为可能。雨后复水通常在半天至1天内完成。相当一部分雨水是通过叶片表面吸收的，但没有证据表明露水能带来明显的复水。复苏植物通常是旱生演替系列中的先锋植物，但它们往往缺乏旱生形态特征。干燥过程中花青素色素沉着是某些物种活力的可靠指标。
