small polygamous, or more usually hermaphrodite, spikes. In the 
latter the receptacle has the form of a small cone, supporting first 
a calyx, formed of from four to six narrow unequal sepals incurved 
Lacistema myricoides.

Young flower, anterior side. Bud in the axil of a bract (2). Young flower, posterior side, 
at the summit when young, persistent, sometimes very small or 
even disappearing almost completely. Within the calyx a glandular 
disk is found, having the form of a circular cupule, nearly regular 
and regularly lobed upon the edges, or more fre- 
quently very unequal and especially developed  Zacistema myricoides. 
upon the anterior side of the flower. More in- 
ternally, the androceum is only represented by 
a single free hypogynous stamen with the fila- 
ment dilated above into a glandular bifurcate 
connective, and each short branch of which 
supports an isolated anther cell, dehiscing 
towards the edges, or a little more within, by eee re 
a longitudinal cleft.’ The free and superior (antero-posterior). 
gynæceum is 1-celled, and attenuated above into 
a style the summit of which separates into three stigmatiferous 
branches, slender, recurved, often very unequal.’ The ovary cell 
contains three parietal placentas, alternating with the divisions of the 
style. Each gives insertion to two or one single ovule, descendent, 
incompletely anatropous, with superior and interior® micropyle. The 
fruit at first slightly fleshy, ends by becoming a loculicidal capsule,
