Bulbophyllum sessile is a miniature orchid species.  This epiphytic orchid originates from a number of places in South East Asia, including: Fiji, Burma, Java, Laos, Malaysia, New Guinea, the Philippines, Thailand, and Vietnam.  This little orchid can be seen growing on the small, twiggy branches of trees, it’s usually found growing in areas of evergreen forest.

Bulbophyllum sessile flourishes in cool and intermediate, to warm temperatures. 

Pyrrosia serpens is an epiphytic fern, which can sometimes be found growing as a terrestrial (on the ground).  Pyrrosia serpens originates from New Zealand and Fiji.  This fern flourishes in warm temperatures from 20C (68F) to 26C (79F).  Although, I must say that my fern is growing very happily in a room with a temperature range from 16C (60F) to 25C (77F).
