Description from The Citrus Industry Vol. 1 (1967):

" 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.
      Lemon or lime characters in the alemow are discernible, and there is some suggestion of pummelo.  The writer has provisionally placed the alemow in this group, and it is included in this treatment because of its promise as a lemon rootstock in California where the soluble salt and boron content of the soils is unfavorably high for the commonly used rootstocks.  Alemow is said to be native to the Island of Cebu, Philippine Islands."

 

Availability: Commercially available in California through the Citrus Clonal Protection Program.
