Part Shade Hot Warm LATER Fall

Common Name or Meaning Morrison's Dendrobium

Flower Size .44 to .64" [1.1 to 1.7 cm]

Found in Vanuatu in mixed forests on ridges at elevations of 250 to 900 meters as a miniature to medium sized, hot to warm growing epiphyte with pendent, many noded, each slightly constricted basally, yellow green becoming purple with age, curved, spreading stems enveloped by leaf sheaths and carrying silky, elliptic-lanceolate to oblong-lanceolate, pale to dark greeen leaves that blooms in the later fall on about 10, mostly arising on leafless stems, .4" [1 cm] long, 10 to 20 flowered inflorescence.

Often cited as a synonym of D purpureum, Dauncy and Cribb resurrected it in 1993 in Kew Bulletin 48[3]. There is a less noticible apical hook to all the floral segments in this species than in D purpureum and there are no prominent wings on the ovary such as in D catillare.
