Family 73. PYROLACE^. Herbs, evergreen, 
or saprophytic and + colourless. Lea. spiral. 
Flow, actinomorphic, in a terminal raceme or 
solitary, 4 — 5-merous, obdiplostemonous. Pet. free 
or united at base. Sta. hypogynous. Carp. (4 — 5), 
with I style ; ovary imperfectly 4 — 5-celled ; ovules 
00, very small, anatropous ; plac. thick, fleshy. Fr. 
a loculi cidal capsule. Seeds endospermous, with 
loose testa. Pyrola, Monotropa. 
Family 74. ERICACE^. Undershrubs, shrubs 
or even small trees. Lea. (with few exceptions) ever- 
green, leathery, often narrow and xerophytic, spiral, 
opposite or whorled. Flow, solitary or racemose, 4 — 
5-merous, actinomorphic or slightly zygomorphic, 
obdiplostemonous or isostemonous.* Pet. generally 
united. Sta. on the edge of an hypogynous or epi- 
gynous disc ; anthers often with appendages (horns) ; 
pollen in tetrads. Carp. (4 — 5), with i style; ovary 
superior (inferior in V accinium) ; ovules i — 00 in 
each carp., pendulous, anatropous; plac. axile. Fr. 
a capsule (loculicidal, septicidal or septifragal) ,

* If these flow, are isostemonous, it is the inner whorl 
that is present ; but, while this would in an ordinary way 
be antipetalous, yet in the Ericaceae (which are typically 
obdiplostemonous) this inner whorl will alternate with the 
petals.
