Received: 0 Oct. 08 / Accepted 0 Dec. 08 / Publication date: 4 Dec. 08 ABSTRACT This study includes taxonomic revision, documentation, description and distribution of Pinus species cultivated in Egypt. Fresh specimens were collected from three gardens; The Agricultural Museum, ElOrman and the Zoo Gardens. Seven species and one variety were collected, identified, described and compared with the specimens in the herbarium of Flora and Phytotaxonomy Researches Department (CAIM). Three new species and one variety were deposited in the herbarium namely; P. brutia Ten., P. brutia Ten. var. eldarica (Medw.) Silba., P. canariensis C. Smith and P. sylvestris L. Herbarium specimens were examined and photographed to help in establishing database information and to be available for the taxonomic researchers to further study of this genus. This study showed the importance of morphological traits for taxonomic evaluation among the studied taxa of Pinus in Egypt. Moreover a constructed key to Pinus species is provided. Keywords: Pinaceae, Pinus, Resinous trees, Coniferous Introduction The family Pinaceae is trees or shrubs, including many of the wellknown conifers of commercial importance contains genera and 0 species (Farjon 998). According to the characters of cone and seed, Pinaceae are divided into four subfamilies; Pinoideae, Piceoideae, Laricoideae and Abietoideae (Frankis 989 and Farjon 990). Among Coniferous the pines constitute by far the most important group regarding either from the point of view of number of species or that of economic value (Bean 9). The true pines are evergreen resin yielding trees belonging to the tribe Abietineae. Pines widely distributed in the northern hemisphere from the limit of tree growth on the plains of North America to the subtropical region of North Africa. Many pines yield timber of economic importance which is used for innumerable purposes. Several species yield an oleo resin which by distillation produce turpentine and resin (Dallimore and Jackson9). Pinus L. is the largest genus of gymnosperms including more than 0 species (Little & Critchfield, 969; Farjon & Styles, 997; Debreczy & Rácz, 0). Pinus L. is composed of two subgenera, Strobus (D.Don) Lemmon and Pinus (Little & Critchfield, 969; Gernandt et al., 005), both of which have limited distribution in the Northern Hemisphere, except for one species of subgenus Pinus (Little & Critchfield, 969; Farjon & Styles, 997; Price et al., 998; Debreczy & Rácz, 0). Pinus L. appeared no later than the early Cretaceous, as indicated by the occurrences of P. belgica (Alvin 960) and P. yorkshirensis (Ryberg et al., 0) in deposits of this period. Fossil ovulate cones of Pinus are found abundantly in deposits younger than the early Cretaceous (Miki 957, A xelrod 986, Mai 986 and Yamada et al., 04). There have been many attempts to reconstruct the phylogeny of Pinaceae, including fossil Pinus spp., defined by their ovulate cone features (Smith & Stockey 00,Gernandt et al., 0, Ryberg et al., 0 and Smith et al., 07). Based on molecular phylogenetic analysis (Gernandt et al., 005). Subgenus Strobus is subdivided into three sections Parrya Mayr, Quinquefoliae Duhamel and Trifoliae Duhamel. Section Mayr is composed of subsections Nelsoniae van den Burgh, Balfourianae Engelm. and Cembroides Engelm. Section Quinquefoliae Duhamel is composed of subsections Gerardianae Loud., Krempfianae Little & Critchfield and Strobus Loud. Subgenus Pinus is subdivided into section Pinus which is composed of subsections Pinaster Loud. and Pinus. Section Trifoliae Duhamel is composed of subsections Australes Loud., Ponderosae Loud. and Contortae Little & Critchfield. Corresponding Author: Fatema S.

The aim of this study was to carry out a taxonomic revision of genus Pinus L. in Egypt and construct a more recent identification key for the studied taxa. Materials and Methods The present study includes eight taxa of Pinus L. collected fresh from three gardens in Egypt as shown in (Table ). The taxa were identified by means of comparison with authentic specimens kept in the herbarium of the Flora and Phytotaxonomy Research Department (CAIM) In addition to botanical keys of Bailey (949), Zohary (966), Davis (975), Humphries (98) and Thompson (99).

VI Numerical analysis of morphological characters: The herbarium specimens were examined and photographed (Plate ). Morphological characters of collected fresh specimens of studied taxa were examined (Plates,, 4 and 5). The relationship between the studied taxa has been analyzed using morphological characters (Table ) by Average Linkage (Between Groups) of SPSS programme (Fig. ). 69

Fig. : UPGMA dendrogram showing the degree of similarity among the studied taxa in Pinus L. in Egypt Discussion Survey, taxonomic revision, documentation and description of Pinus L. species in Egypt were carried out. Fresh specimens were collected from three major gardens; The Agricultural Museum Garden, the Orman Garden and the Zoo Garden. Seven species and one variety were collected, identified, described and compared with the specimens in the herbarium of Flora and Phytotaxonomy Researches Department. Three new species and one variety were added to the herbarium; P. brutia Ten., P. brutia Ten. var. eldarica (Medw.) Silba, P. canariensis C. Smith and P. sylvestris L. Herbarium specimens were examined and photographed to help in establishing database information and to be available for the taxonomic researchers to further study of Pinus L. morphological characters were used by Average Linkage (Between Groups) of SPSS programme to investigate the taxonomic relationship between the studied taxa. The results showed that the studied taxa were grouped into two major clusters. The first one consisted of three taxa; P. sylvestris, P. halepensis and P. densiflora while the other taxa were found in the other cluster. These results were agreed with the infrageneric classification of Pinus L. according to (Farjon 998) in except that P. halepensis was added to the first subsection in addition to P. sylvestris and P. densiflora. the three taxa were similar in 9 characters from the characters. 694
