esse, nulla vera affinitas. Ordo assidue elaboratus est per Sehottium, qui multo acumine species 
ordinavit et tribus, subtribus, et genera, sumpta pro maxima parte de exemplaribus vivis, fundavit : 
nimia tamen genera proposuit secundum singulos characteres. Engler multa genera Schottiana

haraeteres histologicos axis i i conditum, quod nobis videtur maneum quoad explicationem
