The fact that there are woods in which all ray cells are upright seems not to have been mentioned in wood literature prior to my paper on juvenilism in woods (Carlquist, 1962), and I now propose that we confront the physiological significance of prolonged juvenilism in woods.
Rays are composed wholly of upright ray cells, a feature of permanent juvenilism, which is also suggested by the pitting in vessels (Fig.
Juvenilism in Wood: Redirection of Flow Patterns of Photosynthates
The result is not only an unassailably auteurist cinema shot through with signature traits, but a cinema that in its narrational complexity counters Dixon's totalizing charge of Hollywood juvenilism.
(54) Curiously, McGregor's book exhibits all of the main conclusions highlighted by Wiley Lee Umphlett in The Sporting Myth and the American Experience that are common in popular American sporting fiction, presenting "young athletes who are: 1) anti-urban in their basic mindsets and always longing for a return to a simpler life closer to nature; 2) anti-feminine and incapable of coping with women; and 3) victims of a prolonged juvenilism, clinging to memories of youthful glory and rarely attaining enough maturity to grapple with adult problems." (55) Perhaps the critical and popular success of The Last Season is because it tends to conform to such American literary constructions.
Quantitative data included here as indicators of relative mesomorphy or xeromorphy of particular woods, and as a way of documenting presence of protracted juvenilism (paedomorphosis).
The rays are Heterogeneous Type IIB of Kribs (1935), with the proportion of upright to procumbent cells varying according to degrees of wood juvenilism. Tall non-storied rays composed chiefly or entirely of upright cells are indicative of paedomorphosis in wood of the genus.
The degree of juvenilism in wood of Batis is not markedly pronounced, and the wood does not qualify as genuinely paedomorphic.
This may be correlated with the relative juvenilism of resedaceous woods.
25c), suggesting that in a number of species, ray histology is transitional to Paedomorphic Type I (Carlquist, 1988); this indicates some degree of protracted juvenilism in ray structure.
This feature is present in species with protracted juvenilism (also termed paedomorphosis, which implies sexual reproduction while in a juvenile state of development).
By foreshortening this developmental sequence, a kind of juvenilism, the phytelephoid palms have heterochronically attained this condition, which is compatible with their wet forest habitats.
