Description:

Description: English: Inflorescence architecture in Dichorisandrinae s.s. A diagram of the basic Siderasis Raf. emend M.Pell. & Faden inflorescence type, consisting of a thyrse reduced to a solitary cincinnus B diagram of the basic Dichorisandra inflorescence type (also characteristic of S. spectabilis and S. zorzanellii), consisting of a many-branched thyrse with alternate, many-flowered cincinni C diagram of the basic D. acaulis species group inflorescence type, where the main florescence axis and cincinni axis are greatly reduced, and the pedicels are peculiarly elongated. P = prophyll; pB = peduncle bract on main synflorescence axis; * = aborted or dormant apex of main inflorescence axis (usually not observed); B = cincinnus bract; b = bracteole; f = flower; 1°bud = bud terminating cincinnus; 2°bud = bud in axil of peduncle bract with potential to develop into a secondary thyrse (coflorescence); Modified from Pellegrini (2017).
