 subterminal axillary racemes which are longer than the petiole ; peduncle 

 and pedicels puberulous. Calyx irregularly 4(-5)-toothed. Petals 4 

 (rarely 5), oblong, dotted with green on the outside. Stamens 30-35. 

 Ovary 11-16-celled. Fruit, juice-cells spindle-shaped. " There are two 

 varieties of shaddock. In var. a. maliformis, the fruit is globose, with 

 the pulp of a pale pink colour, approaching to a very light yellow. In 

 var. b. pyriformis, the fruit is more or less pear-shaped, the pulp is of 

 a crimson colour more or less intense. The second of these varieties is 

 the more esteemed, being sweet and juicy, and having only in a slight 

 and palatable degree the acridity which abounds in the first " (Macfadyen).
