Source: Received as seed from Florida, 1998.
Parentage/origins: Parent unknown.Seed collected at DPI Arboretum from 7-11E. This DPI source was budded from USDA Orlando source H-830 = PI 410943. This was also received from the same source in 05/1994 and designated RRUT 20, but was discarded to reduce confusion in the database and that RRUT was inactivated.
Rootstocks of accession: Own root.
Season of ripeness at Riverside: Year round Season of flowering at Riverside: May
Notes and observations: RRK, 08/2006: This accession was introduced twice from the same source (12/1989 and 05/1994). Due to adminstrative issues, only the single accession number was given to both introductions. All current trees are derived from original (12/1989) introduction. Although these were seed introductions, the fruit and foliar morphology matches the published description (Winters, HF. 1976. Microcitus papuana, a new species from Papua New Guinea (Rutaceae). Baileya, 20(1):19-24. This accession is not the original introduction (PI 355305) but was ollected in the same area. Description from The Citrus Industry Vol. 1 (1967): "
Twigs minutely puberulous; leaves dimorphic, those on young seedlings greatly reduced cataphylls gradually merging into small, linear or elongate-elliptical leaves and finally into the normal foliage of the species; mature leaves more or less coriaceous, strongly veined, glabrous except in midrib near base; petioles short, wingless, finely pubescent, especially on the upper flattened side; spines slender, acute, single (or in pairs in M. inodora and M. maideniana) in the axils of the leaves; flowers small, 4-5-merous, stamens entirely free, ovary with 4-8 locules; ovules several, 4-8 or more in each locule; fruits round-ovoid or cylindric; pulp-vesicles noncoherent, slender-stalked, subglobose or ovoid (except in M. australis, in which they are elongate-fusiform, tapering above), filled with acid pulp having minute droplets of acrid oil aggregated along the axis; seeds small, ovate in outline; cotyledons hypogeous in germination.
