[The authors show two micrographs from sections of an Asphondylia cytisi gall from an apparently cultivated Cytisus hybrid (listed as "Cytisus praece" which does not appear in IPNI, but perhaps is a typographical error referring to the commonly cultivated Warminster Broom, Cytisus ×praecox Bean). The micrographs are almost unconnected to the text, with all information about them apparently restricted to the captions. Elsewhere they do report that all their samples came from either Kansas or Missouri. It is not clear whether this includes the broom galls.]

Closed, swollen flower...This damage was attributed to Asphondylia cytisi Frauenfeld, but the gall makers were not preserved. The host for this record, exotic to North America, was growing in the New York Botanical Gardens. No other reports are known of the European A. cytisi in North America. Host: Cytisus sp.

[note: Gagné cites a Scientific American article for this entry, but that article only mentions this gall in passing with no details. One of the authors of that article, Lekh Batra, did publish on this species earlier, and that article may be the partial basis for the information in Gagné's handbook entry, or perhaps the handbook entry is based on a museum gall specimen?]
