plant that grows on other plants for support only obtaining nutrients
from the air and rain. A plant having the characteristics of an epiphyte
is called epiphytic. [see
epiphyte – A plant usually growing as an epiphyte but rooted on
the ground. A plant that has the ability to grow under different conditions.
– A tribe, whose members are mainly distributed in the tropical forests
of Central America and include a wide variety of climbing and epiphytic
cacti with flat or ribbed stems bearing diurnal and/or nocturnal flowers.
Representative taxa include Disocactus, Epiphyllum, Hylocereus, Selenicereus
and Weberocereus. [see picture gallery]
– A plant growing among stone or rock.
– A widely distributed and taxonomically complex group ranging from
southwestern US, Mexico, Central America (including the Caribbean) to
Venezuela. Large plants with columnar, ribbed stems. Flowers nocturnal
and diurnal. Major genera include Acanthocereus, Bergerocactus, Carnegiea,
Corryocactus, Echinocereus, Escontria, Pachycereus, Peniocereus,
and Stenocereus. [see picture gallery]
– The host plant of the epiphytic species.
– A tribe distributed in eastern South America (with the exception of
Rhipsalis baccifera which is the only species in the Old World)
and the epiphytic counterpart of the Hylocereeae. It includes epiphytes
and lithophytes with pendulous or creeping growth habit but never climbing.
The stems are varied, from round, segmented, angled to flat with small
diurnal flowers. Main genera: Hatiora, Lepismium, Rhipsalis, Schlumbergera.

– Plant living only as epiphyte on the canopy of a host plant or porophyte.
– A plant living/rooting on the ground.

Vivipary – The germination of seeds within the fruit prior to
abscission from the maternal plant. Two main types of vivipary
are known in vascular plants: true vivipary and pseudovivipary.
