Based on this development, mathematical models predict that roughly 15% more plant species exist than are currently known, for a total of some 350,000 species – a figure that is consistent with expert opinion. Perhaps half of the undescribed species have already been collected and housed in herbaria, where they await detection and analysis.
在现有基础上，数学模型预测植物总共约有350,000种，比目前所知的多出15%左右。这一数字与专家意见其实不谋而合。也许半数未确定物种已经被搜集到植物标本室，现在正在那里等待分析和检验。
