filamentous

In structure they are expanded or filamentous, nearly always rose-coloured or purple in colour.

Pod 1° long, with linear stalk, containing many seeds separated by filamentous isthmuses.

In a similar way the petals and labellum of Odontoglossum Uro-Skinneri have been found reduced to filamentous processes.

Usually the protonema is filamentous and ceases to be evident after the plants have developed.
