ACANTHEPHIPPIUM. 111 
The sepals and petals are pure white; the lip is also white, or yellow with.purple 
or orange veins, the crested lamine being orange. In Burma is found a form (which 
has been named var. Bensoniw) with rose-purple sepals and petals, and a deep purple 
lip white at the base. In Sikkim there is a form rather smaller in all its parts than 
the type, and with a shorter congested raceme, but not differing in form. This smaller 
form is epiphytal and does not ascend above an elevation of 3,000 feet. It is No. 171 
of Mr. Pantling’s gathering.
