" Microchilus jamesonii is very similar to M rosea but diffres from the later by having almost glabrous sepals versus sepals densely glandular outside. Additionally the petals of M jamesonii are oblong-sagittate above a narrow base versus obliquely linear-spathulate and the epipchile lobules are touching each other above the hypochile versus separated lobules."
