However, the basic condition seems to be axile
placentation with a simple septum (type 1), from which the other specialized patterns would have arisen, through different modifications and degrees of complexity of the placentas.
They concluded that roots could extract water and nutrients from aggregates, even without axile root penetration of the aggregates.
This duration avoided excessive growth of roots and restricted the root development to the primary axile system (tap and basal roots and their laterals; see Zobel, 1991).
possible enclosure in a persistent floral tube, a superior ovary with axile
placentation, eight locules, loculicidal dehiscence, and possibly two rows of seeds (described as two seeds in each locule, but serial diagrams suggest the condition may be two or more rows of seeds per locule), and an undifferentiated seed coat.
The fossil and living taxa share the following characters: persistent floral tube, valvate sepals (unknown in Minsterocarpum), superior ovary, axile
placentation, capsular fruit, loculicidal dehiscence (unknown in fossil Decodon), septum attached to outer wall of the valve at dehiscence, multiple anatropous seeds per locule, and a t obtrigonal shaped seed body with a sclerotic inner lining of the seed coat.
monocephalus), while most Miconieae have axile
placentation with expanded and/or somewhat divided placentae.
Ovary 5-locular, with axile
placentation, superior; style long, impressed; stigma not expanded.
Gynoecium bicarpellate, syncarpous, superior, usually unilocular and oriented in the antero-posterior plane; surrounded by nectary-disk or distinct glands; placentation parietal (this occasionally bifid) or rarely free axile
, seldom bilocular with axile
placentation: style simple and terminal, with entire or bilobed, papillate stigma, rarely style wanting and stigmas decurrent on ovary (Lomatogonium); ovules usually numerous and anatropous.
Una de las mayores diferencias radica en el hecho que en los cartilagos claviculares, la proliferacion celular ocurre en el tejido conectivo de la capa proliferativa y estas celulas no forman columnas, en cambio en los huesos largos, la actividad mitotica ocurre en la zona de cartilago hiperplasico, a partir de condrocitos en reposo, donde originan los grupos isogenos axiles
