Leaves succubous, circular to oblong-ovate, rounded, usually with very conspicuous yellow gemmae produced at the upper margins, concave, costa none. |
|
I know of no other genera with such intramarginal formation of true gemmae. |
|
The moss has tiny leaves shaped like spears with reproductive structures called gemmae at their tips which disperse to help spread the moss. |
|
Though gemmae are of interest to morphologists, they have been used only rarely as aids in identification. |
|
It is unknown whether the leafy stage can produce such gemmae. |
|
The short shoots were firmly attached to the main shoot and, unlike normal gemmae, showed no evidence of an abscission layer above the proximal leaves. |
|
Gemmae are frequently longer than wide or of irregular shape. |
