Notes:
This name is provisionally separated here but may be a synonym of Hoffmannia calycosa. The younger inflorescences of this colleciton match that species. However several stems are included in this collection, and show that as flowering proceeds and the inflorescence develops, the peduncles, axes, and pedicels elongate at least shortly to produce a shortly cymose inflorescence. Standley regarded this collection, Purpus 7268 as a mixed comprising two different species, which he described as Hoffmannia chiapensis and Hoffmannia rotundata. However this seems to be one collection with inflorescences at different stages of development. The leaves of this species are elliptic to broadly elliptic, in contrast to the oblanceolate leaves typical of Hoffmannia calycosa. This specimen also has been included in Hoffmannia nicotifolia, but does not match that species as circumscribed here. This group of plants or species has not been carefully studied to find other specimens that match this type, to better understand this species: that task remains for the future. Standley's two names were published simultaneously. The name Hoffmannia chiapensis is used here, because that protologue described the inflorescences as shortly cymose. The duplicates of Purpus 7268 have generally equal numbers of branches with young, subcapitate inflorescences and older cymose inflorescences, but the description of Hoffmannia rotundata is not completely accurate: it describes the inflorescences as subcapitate, however there are lax cymose inflorescences also present on this specimen.
