anadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the apex of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |

|
androphore |
>< stalk |
STRUCTURE |
|
A stalk or tube that rises above the level of perianth insertion and bears the distinct portions of the androecium from its summit; as in Malvaceae, where the androphore is a tube formed by connation of the filaments. |
