This suggestion seems particularly attractive because the proposed causal agents for the peculiar morphology of divaricate shrubs, i.e.
This is the case for atmospheric species in the tillandsioids (Tomlinson, 1970), aroid vines such as Monstera tuberculata, which produces only saucer-shaped leaves throughout their life time (Lee & Richards, 1991), life-long carnivorous plants as descendents of species, in which carnivory was originally restricted to the early stages of ontogeny as in a few extant species (Barthlott et al., 1987), or divaricate shrubs that may have arisen from heteroblastic trees after losing the original adult state (Day, 1998).
New Zealand's divaricate shrubs avoid photoinhibition.
Towards a numerical definition for divaricate (interlaced small-leaved) shrubs.
Racemes several to many flowered, dense or lax, ebracteate, corymbose, elongated slightly in fruit; rachis straight; fruiting pedicels slender, ascending to divaricate. Sepals oblong, ascending to spreading, equal, pubescent with dendritic or forked trichomes; petals white, obovate to spatulate or oblong; claw distinct, basally pubescent or minutely papillate; stamens 6, slightly tetradynamous; filaments wingless, unappendaged, basally pubescent or minutely papillate, free; anthers oblong; nectar glands confluent, subtending bases of all filaments; ovules 30-54 per ovary.
Racemes several or many flowered, ebracteate, corymbose, elongated slightly or considerably in fruit; fruiting pedicels slender or thickened, ascending to divaricate, very rarely reflexed.
Racemes several to many flowered, lax, ebracteate, corymbose, elongated considerably in fruit; fruiting pedicels slender, strongly recurved or reflexed, rarely divaricate or ascending and straight, persistent.
