sub-acute, spreading. Petals shorter than the sepals, faJcately elliptic, obtuse. Idp
equalling the sepals, broadly elliptic or obnvate, entire or obscurely 3-lobed, tho
edges crenulate; upper surface slightly pubescent, with many shallow grooves extending
from tlie base nearly to the apex; spur stout, obtuse, about half as long as the
ovury. Poliinia pyriform. a little longer than the rather stout tapering caudicles;
glands ellijitic enclosrd in a pouch formed from the rostellum. Staminodes small,

Terrestrial leafy herbs with undivided or lobed tubers or fleshy root-fibres,
not plaited, their bases sheitUing. Flowers in racemes or spikes. Sepab subequal, the
dorsal often connivent with the petals to form a hood over the column; the laterid pair
spreading, leflexed or deflexed, or sometimes erect. Petals smaller or larger than the
sepals, entire or 2-oleft. Lip adnate to the base of the column, eniiie, 3 lobed or 3-
partite, its base spurred. AnHicr-colls adnate to the front of the short and usually broad
column, discrete, rarely touching, parallel or divergent below, their bases often prolonged
into tubes containing the caudicles. Staminodes represented by two granular more or less
conspicuous projections on the outer side of each anther-cell, rarely elongate, rollinm
two, clarate or pyriform, usually grooved, sometimes 2-pai-tite; caudicles varying in
lengtli, somotimes absent; glands exposed, flat and discoid, or elliptic or globular, or
elongate with truncate ends (conjoined and enclosed within processes of the 2-lobod
rosteUum in E. secmdiflora). Stigmas two, distant from each other or united to foi-m
