Barker, W.G.
The banana leaf must pass through a prolonged growth period while totally within the pseudostem and with the lamina in an involved double coil. During this time the blade makes most of its growth, completing the last fourth of the expansion as it emerges. In this same latter period it accomplishes almost two-thirds of its elongating growth. The first few leaves of a single plant are essentially bladeless. Thereafter the size of the lamina increases in both dimensions with each succeeding leaf tending to exceed its predecessor. A diurnal/nocturnal cycle is evident in both Costa Rica and Honduras and maximal elongation coincides with the highest temperature in the daylight hours. Control of elongation is elegant with each leaf developing at a rate governed by those ahead of it. An assessment is made of the stomatal occurrence over the surface of the blade.
