Part shade Warm Summer Fall

Common Name Hooker's Elleanthus [English Botanist 1800's]

Flower Size .4" [1 cm]

Found in Brazil and Bolivia in wet montane forests at elevations of 600 to 700 meters as a large to just giant sized, warm growing epiphyte with simple, erect, caespitose, arched stems enveloped by remainders of leaf sheaths and carrying coriaceous, plicate ovate-elliptic, acute to acumnate, narrowing below into the clasping base leaves that blooms in the summer and fall on a terminal, arching, capitate, covered with mucilage, many flowered inflorescence with imbricate, rigid, triangular floral bracts and carrying basally white flowers with magenta towards the apices of the segments.

Similar to E capitatus as both have the lip calli more or less subglobose, not decurrent onto the disc. The lip of E hookerianus is broader than long, transversely elliptic-flabellate in outline, the apical margin is subtruncate, more or less incised in front and minutely denticulate or erose fimbriate. The lip of E capitatus is longer than wide, broadly obovate to elliptic-obovate in outline, obscurely trilobed in front and has a finely erose-dentate margin." Szlatchetko & Kolanowska 2023
