Zamia

American genus of cycad; causes incoordination, due to degeneration of the spinal cord, and hepatic necrosis. The toxin is identified as a cycad glycoside. Includes Z. integrifolia (Z. floridana), Z. portoricensis, Z. pujilla, Z. pumila (Z. debilis, Z. latifoliata, Z. silvicola, Z. umbrosa).

The midrib of Zamia restrepoi is raised both adaxially and abaxially, although it is more prominent on the adaxial surface (Fig.
The fiber clusters are entirely restricted to the veins, as in Zamia disodon.
This was noticed in the samples of Zamia disodon, in which the abaxial density of stomata seemed higher compared to the upper surface.
In Zamia disodon, a very uncommon leaf feature was observed: the leaflet veins are raised on the adaxial surface, but flat at the abaxial side of the leaflet.
The conspicuous midrib seen in all leaflets of Zamia restrepoi was the main trait used to separate this species in the genus Chigua D.
The abundance and size of the air chambers in both species could be related to the very humid environment of the wet forest undergrowth, where these species are native (Stevenson 2001, Jones 2002), similar characteristics were noticed in Zamia fairchildiana and Z.
El presente estudio tuvo como objetivo evaluar la respuesta al cultivo in vitro con miras a la propagacion masiva de Zamia incognita, que sirva como punto de partida para su conservacion ex situ.

El mayor porcentaje de formacion de callo se alcanzo en los tratamientos con bajas concentraciones o en ausencia de citoquininas en el medio de cultivo, este comportamiento tambien se reporto en Zamia furfuraceae (Dhiman et al.
En el caso especifico de la kinetina Palma (2007), encontro este comportamiento en el proceso de micropropagacion de Zamia skinneri, donde obtuvo necrosis de los explantes con una concentracion de KIN de 3 mg/l.
Estas respuestas diferenciales encontradas podrian ser explicadas por el genotipo, siendo este aspecto evidente al revisar lo reportado en diferentes especies de Zamia (Litz et al.
Con este tratamiento, callos de Zamia pumila aumentaron su diferenciacion y su capacidad para organizarse y formar un mayor numero de estructuras (Webb et al.
