穗状花序

By separation and combination analyses of nuclear rDNA ITS and the cpDNA (matK gene, rpl16 intron and atpB-rbcL spacer) sequences, the interspecific relationships were discussed, and the classification review and biogeographic analysis were done for all species bearing raceme or spike of one to many umbels with prophylla at base.

Inflorescences cymose, umbellate, corymbose, in paniculate clusters, or a cincinnus, rarely flowers single, fascicled, or born on a spike; bracts sometimes conspicuous and persistent.

花序聚伞状，伞形，伞房状，以圆锥状丛生，或蝎尾状聚伞花序，很少单花，簇生，或者生于在穗状花序上；苞片有时明显并且宿存。

Inflorescence a terminal spike on pseudostems or on separate shoots arising from rhizomes, sometimes appearing before leaves; peduncle erect; bracts connate for ca. 1/2 their length and forming pouches, spreading at free ends, each subtending a cincinnus of 2--7 flowers, apical bracts often differently colored, large, sterile, forming a coma; bracteoles free to base.

顶生穗状花序生假茎或独立的由根状茎生的嫩枝，有时出现在叶之前；花序梗直立；苞片合生约1/2的其长度和形成小袋，小苞片离生至基部。

Any of numerous shrubs or small trees of the genus Combretum having spikes of small flowers.
