Explanatory Note by W. B. H. 
In 1843 Dr. F. L. von Schlechtendal described a Mexican tree at 
considerable length (Linnaea, vol. xvii. pp. 635-8) under the name 
of Hypopterygium adstringens, which he subsequently (op. cit. p. 745) 
changed to Juliania adstringens. In the same place Schlechtendal 
concludes with the following statement : ‘ Epitheton adstringens a beato 
amico [Schiede] in schedula datum verosimiliter vim adstringentem 
hujus arboris indicat. Amici nomen genericum Amphipterygium , 
quum ala basalis tantum nec cingens adsit, rejecimus V With regard 
to its position in the Natural System he could only indicate remote 
affinities to various orders. Bentham and Hooker (Genera Plantarum, 
vol. i. p. 428) placed it doubtingly at the end of the Anacardiaceae. 
Engler (DC. Monogr. Phanerog. vol. iv. p. 500) places it in the ‘ genera 
ex Anacardiaceis excludenda,’ adding : ‘ Quamvis canales resiniferi 
1 It is a pity that Schlechtendal did not adopt Schiede’s generic nam t Amphiptery* 
gium, especially as he gave publicity to it himself, because both Hypopterygium and 
Juliania had already been used, and his objection to Schiede’s name is unsound, 
the fruit being winged on both sides of the axis. As it is not improbable that 
►Schiede’s name will be revived by somebody, we have repeated our names under 
Amphipterygium , though we should prefer retaining Juliania.
