Honey Plants of Düzce University Ornamental and Medicinal Plants Botanical Garden

In this study, melliferous plants that the honey bee (Apis mellifera L.) can benefit from among the taxa planted in Düzce University Ornamental and Medicinal Plants Botanical Garden, are presented. Among the 451 taxa planted in the botanical garden, those with these characteristics were determined by reviewing studies on the subject. Of the 165 taxa (36.58%) included in the honey plant class; 119 contain both nectar and pollen, 25 contain pollen, 13 contain nectar, 4 contain both pollen and insect secretion (IS) or sweet sap (SS), 2 contain pollen, nectar and IS or SS, 1 contain both nectar and SS, 1 contain only IS. In order to prevent the decrease in pollinator and pollinator insects, whose numbers are decreasing due to global climate change, a "Bee and Insect Hotel" was placed in the botanical garden. For this reason, the majority of the plants selected for planting were chosen from taxa with honey plant properties. The main purpose here is both to pollinate the plants in the botanical garden and to show and explain the effects of insect species on pollination through nature education

Polygonum orientale (?Persicaria orientalis; Polygonaceae) in Turkey re-discovered after 73 years and considerations about its status

Polygonum orientale (? Persicaria orientalis; Polygonaceae), a specie native to a wide region from India to Far East Russia and extending to North and South Australia. For this reason, in here, this taxon is recorded as a new alien species for Turkey. The species was first recorded in Turkey in the Marmara region (Sakarya province, Adapazarı district) in 1936. Subsequently, it was found in the Central Anatolia (Ankara province) in 1942, in the Eastern Black Sea Region (Rize province) in 1945, and finally in the South Eastern Anatolia (Urfa province) in 1947. Our finding represent was the first one in the Western Black Sea Region (Düzce province, Kaynaşlı district), 73 years after its last detection. Information about the current distribution and habitats of this species in Turkey, as well as its complete morphological description, were provided

Düzce'de doğal olarak yayılış yapan Heracleum L. taksonları, habitatları ve bu habitatların floristik kompozisyonu

Düzce ilinde doğal olarak yayılış yapan Heracleum L. taksonları, taksonların bulunduğu habitat tipleri ve bu habitatların floristik kompozisyonunun araştırıldığı bu çalışma 2018 yılında yürütülmüştür. Arazi çalışmaları sonucunda Heracleum platytaenium ve Heracleum sphondylium ssp. ternatum olmak üzere Düzce’de iki farklı Heracleum taksonunun; tarımsal, şehir, kıyı, orman, riparian ve yapay habitatlar olmak üzere altı farklı habitatta yayılış yaptığı belirlenmiştir. Habitatlardan alınan örnek alanlarda Heracleum spp. ile birlikte yayılış yapan 48 familya ve 112 cinse ait 150 takson belirlenmiştir. Araştırma alanında tespit edilen 121 taksona (%80,66) ait fitocoğrafik bölgeler belirlenmiştir. Buna göre; 8 takson Öksin kesime ait olmak üzere 36 takson (%24) Avrupa-Sibirya, 17 takson (%11,33) Akdeniz ve 1 takson (%0,66) İran-Turan kökenlidir. Ayrıca 67 takson (%44,66) geniş yayılışa sahipken 29 takson (%19,33) ise çok bölgelidir veya fitocoğrafik bölgesi bilinmemektedir. Raunkiaer’in yaşam biçimlerine göre taksonlar incelendiğinde; 73 takson (%48,67) Hemikriptofit iken bunu sırasıyla; Terofit (48 takson - %32), Fanerofit (14 - %9,33), Kriptofit (10 - %6,67) ve Kamefit (5 - %3,33) bitkiler takip etmiştir. Son olarak taksonların habitatlara göre hangi bitki taksonları ile bir arada yaşadıkları ayrıca sunulmuştur.This research was done in Düzce during 2018 to study the taxa of naturally distributed Heracleum L., natural habitats of the taxa and floristic composition of the habitats. Results of the field study showed that two different taxa of Heracleum L. including Heracleum platytaenium and Heracleum sphondylium ssp. ternatum were determined in six different habitats such as agriculture, urban areas, coastal areas, forest, riparian and artificial habitats. From the samples collected from the habitats, it was determined that 150 taxa belonging to 48 families and 112 genera were present along with the Heracleum spp. The distribution of the taxa found in the study area was examined according to phytogeographical regions and as a result, regions belonging to 121 taxa (80.66%) were determined. According to this; 8 taxa belong to the Euxine province while 36 taxa (24%) are of Euro-Siberian, 17 taxa (11.33%) of Mediterranean and 1 taxon (0.66%) are of Iran-Turan origin. In addition, 67 taxa (44.66%) have a wide distribution, while 29 taxa (19.33%) are multi-regional or not known. When taxa are examined according to the Raunkiær plant life-form; 73 taxa (48.67%) are Hemicryptophytes while it is respectively followed by Therophytes (48 taxa - 32%), Phanerophytes (14 - 9.33%), Cryptophytes (10 - 6.67%) and Chamaephytes (5 - 3.33%). Finally, it is also presented that plant taxa living together with Heracleum spp. in their habitats

A New Hybrid Record for The Vascular Flora of Türkiye: Fagus x taurica Popl.

The presence of Fagus x taurica Popl., a hybrid of two Fagus L. taxa known to be naturally distributed in Türkiye, has been detected in the natural deciduous-mixed forests of Bolu. Specimens were collected from Kökez Old Growth Fir Forest Nature Reserve Area, Bolu Kale Fındığı Nature Reserve Area, and Yedigöller National Park in Bolu province, northwest Türkiye. After the identification, specimens were compared with materials in the international herbaria. As a result of the examinations, the morphological features seen to be different from its parents are as follows: Young shoots are grayish-green in color, leaves have 7-13 pairs of lateral veins, are ovate or obovate, and their margins are dentate, and the cupula scales are subulate. It resembles F. orientalis Lipsky in terms of leaf characteristics and F. sylvatica L. in terms of cupula characteristics. In this article, a botanical description of the taxon, differences from the main species, distribution maps, and photos are given. Fagus x taurica is a new hybrid record for the vascular flora of Türkiye. With this new record, the number of Fagus sp. taxa in the flora of Türkiye has risen to 3
