Narrative
Nice looking trees so far, little dieback yet. Had light crop, now on ground. [Swingle and Reece, 1967], pp 353, lists M australasica var sanguinea as the Red-pulp finger-lime and says it varies from pink to red in color. This accession exhibits no pink or red color at all. Pulp is virtually white as it is in all our finger limes in the CRC 3661 to 3672 group. We probably don't have true M australasica var sanguinea. This accession is probably M australasica, purple fruit strain - fruit is relatively large for M australasica and has purplish-green rind color. [PI 306115] came in [to the CES] as purple fruit strain but doesn't seem to be - see that [record]. (EM Nauer, 12/22/1987)

The source history f this accession is confusing. The oldest date on a record is associated with Citrus Experiment Station (CES) documentation and is dated 1924. The record in the Plant Inventory Book (link above) is dated 1935. However, this is the date that the PI was assigned. PI 109773 was included in a group (PI 109606 - 109792) of "[p]lants growing at the United States Plan Introduction Garden, Glenn Dale, Md.; originally grown by the Office of Crop Physiology and Breeding Investigations (CPB), a section of the Division of Horticultural Crops and Diseases. Numbered in January 1935 for convenience in distribution." Therefore, the plants were apparently growing at USDA sometime prior to the numbering and their actual origin is not known at thistime. Other M australasica in the same group receiving PI's originated as seed from Australia, so it is likely that is also the case for PI 109773. If they were sent to the CES in 1924, it is unclear as to why a PI would be assigned at a later date. In some cases, PI's were assigned to incoming seed lots, so it is possible that there were other seedlings still at CPB.
It should be noted as well that the earliest (1924) CES document refers to M australasica var sanguinea. However, the USDA documents (PI Book and hard copies on file at NCGRCD) do not refer to "var sanguinea" but have an italicized or underlined "Sang." after "M australasica". It is not entirely convincing to us that this refers to "var sanguinea", especially given the fruit's characteristics.
In addition, although the earliest CES documentation links the RCRC 1484 with CPB 11411, the association of that CPB with PI 109773 was apparently unknown (especially if the plants were received before the PI number was assigned) and so PI 539734 was assigned in 1990. When this was discovered, PI 539734 was inactivated. Observations and images were originally made when the accession was identified as PI 539734. (RR Krueger, 2009-05-17)
