Alemow Citrus Macrophylla Papeda Budwood

Citrus macrophylla.
Citrus celebica.

Fruit medium-large, oblong to obovate; often with prominent mammilla surrounded by circular furrow; seedy.  Rind medium-thick (for size of fruit); surface somewhat rough and bumpy; tightly adherent; color greenish-yellow.  Segments numerous (about 15); central axis large and solid.  Flesh color greenish-yellow; low in juice; strongly acid and bitter.  Seeds polyembryonic.

Tree vigorous, spreading, very thorny (with short stout spines); flowers and new growth strongly purple-tinted.  Leaves small to medium, pale green, narrow elliptical, blunt-pointed, and with broadly winged petioles of the pummelo type.

Of interest as a lemon rootstock where the soluble salt and boron content of the soils is unfavourably high for the commonly used rootstocks.

Rootstocks of accession:  Yuma Ponderosa lemon.
