-1909) a Scottish medical
doctor and botanist who worked in India starting in 1865 after graduation from
medical school. For a short time he was Superintendent of the Garden at Saharanpur
and Conservator of Forests in that area. From 1870
-1897, he was the Superintendent
of Calcutta Botanic Gardens. During the same period he became the first Director,
Botanical Survey of India (Burkill 1965). His contributions to botany and science
are numerous and far-reaching. The specimen King 1020
(CAL) is the first known
collection of this new species.

The type selected here with a creamy white flower, dark red throat and white
apex is the most common form observed across the range and as depicted in King’s
illustration (Fig. 14). Another form has also been observed with dark pink to light
violet colouring on the apex similar to the colours of B. hamiltonii. Based on limited
observations, this latter form seems to be less robust with shorter pseudostems and
smaller diameter rhizomes. The multi-stemmed habit of B. kingii (in both forms) is
the result of the rhizome morphology—running in habit with multiple growth nodes
similar to a stolon (Fig. 15F). These runners grow outward from the initial plant in
various directions, often producing a new pseudostem at a major node. The result
can be a large, clonal population such as at the type locality, where it encompasses
over 30 m
with hundreds of interconnected stems (Fig. 15C). In ex situ experiments
several pseudostems after one year of growth. In this vein, a specimen from Burma,
statement can now be understood with more clarity—B. kingii has the potential for
rapidly spreading once established in a suitable area.
