MONTIEL, Mayra  e  SANCHEZ, Ethel. Ultraestructura de bambúes del género Dendrocalamus (Poaceae: Bambusoideae) cultivados en Costa Rica II: Dendrocalamus latiflorus var. latiflorus. Rev. biol. trop [online]. 2006, vol.54, suppl.2, pp.51-57. ISSN 0034-7744.

We used a scanning electron microscope to observe leaf laminae, culms, branches, culm bracts and branch buds of Dendrocalamus latiflorus var. latiflorus grown in Costa Rica. In the abaxial epidermis of the leaf lamina we found two types of ceric papillae, rounded and elongated, the latter surrounding the low dome stomata. Only the adaxial surface of the central nervature (leaf lamina) has big hook-sshaped trichomes. In the abaxial zone of the culm bract there are thin elongated trichomes, similar to those from the bract of Dendrocalamus giganteus. The branch buds are covered by bicelular trichomes. Rev. Biol. Trop. 54(Suppl. 2): 51-57. Epub 2006 Dec. 01.
