54 DIMORPHIC BEANCHES IN TEOPICAL CROP PLANTS. 



(3) Inflorescence hranches. — Natal coaxillary branches borne on 

 the temporary branches in chisters of four male inflorescences or two 

 male and one female. 



BRANCHES OF COFFEE. 



(1) Upright hranches. — Natal axillar}- branches not producing in- 

 florescence branches; serving as equivalents of the main stem. 



(2) Lateral hranches. — Natal extra-axillaiy branches attached to 

 the bases of the internodes of the main stem or of the upright 

 branches. Lateral branches produce leaves, inflorescence branches, 

 and secondary laterals, but are unable to replace the main stem. 



(2a) Secondary lateral hranches. — Adventitious branches arising 

 from axillary buds of the lateral branches. They are inflorescence 

 branches pushed into vegetative growth by severe pruning. In form 

 and function they agree with the lateral branches. 



(3) Inflorescence hranches. — Natal and adventitious coaxillary 

 branches borne in clusters on lateral and secondary lateral branches. 



BRANCHES OF CACAO. 



(1) Upright hranches. — Probably adventitious extra-axillary 

 branches, bearing long-petioled leaves and able to produce branches 

 of all three kinds and to become permanent parts of the main stem. 



(2) Whorled hranches. — Natal axillary branches produced in 

 whorls and terminating upright branches. Whorl branches bear 

 short-petioled leaves, lateral branches, and inflorescence branches, but 

 are unable to replace the main stem. 



(2a) Lateral hranches. — Natal axillary branches produced by 

 whorled branches and having the same functions; not producing 

 whorled branches or main stems. 



ijS) Inflorescence hranches. — Adventitious extra-axillary branches 

 arising from the mature wood of the main trunk and the whorled and 

 lateral branches, without power to replace the main stem or the 

 vegetative branches. 



BRANCHES OF THE BANANA PLANT. 



(1) Sioord suckers. — True branches of the rhizome that arise from 

 subterranean buds, develop large bulbous bases, and put forth narrow 

 leaves when j^oung. 



(2) Broad-leaved suckers. — Offshoots adapted for separate vegeta- 

 tive propagation, arising from superficial buds and bearing broad- 

 bladed leaves while still young.
