Structural analysis of sclerophylly in eleven evergreen phanerophytes in Greece. N.S. Christodoulakis and K.A. Mitrakos. Institute of General Botany, University of Athens, Athens 157 01, Greece. INTRODUCTION. In the past (Grisebach 1872; Schimper 1898; Turrill 1929) as well as recently. (Johnson 1973; Mooney et al.
He characterized the types by the amount and kind of protection afforded to the buds and sioot-apices. Dr. Raunkiaer established the following types: I. Phanerophytes. The surviving buds or shoot-apices are borne on negatively geotropic shoots which project into the air. 1. Evergreen Phanerophytes without bud-covering.

Hemicryptophytes have their dormant buds in the upper crust of the soil, just below the surface; the aerial parts are herbaceous and die away
Abstract. Changes in phanerophytic vegetation in a mountain woodland of Central Argentina are analy- zed. Floristic composition, disturbance factors (logging and grazing) and some physical variables are recor- ded in sampling plots located along a gradient of use intensity. Multivariate analysis shows that the main.
Abstract. In the past (Grisebach 1872; Schimper 1898; Turrill 1929) as well as recently (Johnson 1973; Mooney et al. 1974), an evolutionary and ecological importance has been attributed to the leaf structure of the mediterranean evergreen sclerophyllous phanerophytes. Nevertheless, anatomical data on these leaves are
the floristic spectrum, the most represented life-forms were the phanerophytes and the hemicryptophytes, as in other cerrado sites. This spectrum differed significantly from Raunkiaer's normal spectrum, mainly due to under-representation of therophytes and over-representation of phanerophytes. The floristic and frequency

It was first proposed in a talk to the Danish Botanical Society in 1904 and briefly described in the society's journal Botanisk Tidsskrift. A fuller account appeared
(5) Therophytes. Cryptogams are not included in this system: (1) Phanerophytes: ADVERTISEMENTS: In these, the perennating buds are located on the twigs and branches and are exposed to the atmosphere during un-favourable periods. Plants are mostly woody (trees and shrubs), although lianas, epiphytes and some
Phanerophyte: Projecting into the air on stems – normally woody perennials - with resting buds more than 25 cms above soil level, e.g. trees and shrubs. 2 Tree - large. Large tree, also termed a Phanerophyte (>15 m). 3 Tree - small. Small tree, also termed a Phanerophyte (1-15 m). 4 Shrub - size unknown. Perennial shrub
