The spermatheca is oval, very short, on a short stem.

Females have a very complex and an extremely variable reproductive system, commonly known as a spermatheca.

The column of such orchids must act almost like the spermatheca of insects.

It then bends a little backward and is shortly joined by a duct from the spermatheca.

Some species do not have a spermatheca in the traditional sense, but do possess pseudospermatheca.

The female genitalia include a well-developed uterus but no spermatheca.

The dart-sac is long, the spermatheca short and elongately pearshaped.

Sexual material is exchanged between both animals via spermatophore, which can then be stored in the spermatheca.

The spermatheca is spherical, its diameter twice of oviduct.

The peptide stimulates the contraction of the oviducts and spermatheca.

The spermatheca is elongate and relatively short.

Hermaphrodites have two ovaries, oviducts, spermatheca, and a single uterus.

Females possess a spermatheca, an ectodermal gland which opens into the oviduct.

The oviduct is thin; the spermatheca is elongate with a short duct.

The spermatheca is rather irregularly ovate, and increases in size when containing numerous spermatophores.

Microscopically, it can be seen that their spermatheca are sickle-shaped, well developed and darkly pigmented.

The spermatozoa move to the spermatheca in the roof of the cloaca where they remain until ovulation which may be many months later.
