Abstract: Sapria, a holoparasitic plant
of Rafflesiaceae is still understudied in term of anatomical,
even more in histoanatomical study. This study aimed to perform
preliminary observation on Sapria himalayana Griff. f.
albovinosa morphology on its early and late stage of
flower bud development inside its host, Tetrastigma laoticum
Gagnep. (Vitaceae). The results show the progression from the
early flower bud as it starts to grow in the host vascular cambium
area towards proximal direction to reach the host xylem and distal
direction to reach the host phloem and to reach the next stage
of the life cycle, into the late flower bud where differentiation
occurs. In late flower bud, some primordial of the organs are
visible as the flower bud grows larger distally towards the periderm.
This development pattern is similar to the progression of development
in the previous studies in Rafflesia and Rhizanthes,
where endophytic growth was observable in both proximal (xylem
area) and distal (peridermal). Future comparative study is encouraged,
especially to compare between Sapria species and between
different stages of growth. Although, an efficient method and
less invasive way of sampling is encouraged to prevent decline
of Sapria species in the wild.
