Botanical Identification

Ecology

The ecology of Ruta chalepensis is characterized by a broad altitudinal distribution that allows it to inhabit a diverse array of topographical landscapes. The species exhibits significant adaptability to varying heights, with an elevational range that begins at sea level (0 m AMSL) and extends to a maximum altitude of 3000 m AMSL. Within this extensive vertical gradient, the plant maintains a mean elevational range of approximately 1890 m AMSL, suggesting a primary ecological preference for mid-to-high altitude montane environments while remaining capable of colonizing lowland habitats.

Elevational range max:
3000 m AMSL
Elevational range mean:
1890 m AMSL
Elevational range min:
0 m AMSL

Life history

The life history of Ruta chalepensis is characterized by its status as a perennial plant, allowing it to persist through multiple growing seasons. In terms of its structural growth habit and ecological strategy, the species is classified as a chamaephyte, a life form where the majority of the plant's regenerative buds are located close to or just above the soil surface. This classification is consistently identified through both its life form designations as a chamaephyte, ensuring its ability to endure various environmental conditions by maintaining its vital organs near the ground level.

Life form :
chamaephyte
Lifecycle :
perennial

Morphology

The morphology of Ruta chalepensis is characterized by a woody growth form, specifically functioning as a shrub. This plant is a terrestrial species, existing as an independent organism rather than an epiphyte or a parasite. It is a self-supporting plant that does not exhibit climbing or vine-like tendencies. In terms of stature, it maintains a relatively low profile with a plant height ranging from a minimum of 0.3 m to a maximum of 1 m.

Physiology

The physiology of Ruta chalepensis is characterized by a C3 photosynthetic pathway, a common mechanism in many woody shrubs that involves the direct fixation of carbon dioxide through the Calvin cycle. Morphologically, its physiological efficiency is supported by its leaf form, which is distinctly oblong. This leaf structure facilitates optimal surface area exposure for gas exchange and light absorption, supporting the metabolic processes necessary for the plant's growth and the synthesis of its characteristic secondary metabolites.

Leaf form :
oblong
Photosynthetic pathway :
C3

Reproduction

The reproduction of Ruta chalepensis is characterized by bisexual flowers that exhibit a green coloration. The flowering period typically begins in February and concludes in July, though the timing can be variable. These flowers are relatively small, ranging in length from a minimum of 0.39 cm to a maximum of 0.72 cm. The plant utilizes a biotic pollination syndrome, specifically relying on insects to facilitate the reproductive process, while self-fertilization is noted as absent. Following successful pollination, the plant develops fruit in the form of a capsule. These capsules vary in size, with a minimum length of 0.46 cm up to a maximum of 0.69 cm, and a width ranging from 0.4 cm to 0.9 cm. The reproductive output is prolific, with each fruit containing more than 1000 seeds. These seeds are remarkably lightweight, with a mean mass of 0.001381 g, ranging from a minimum of 0.00126 g to a maximum of 0.00156 g. Dispersal of the seeds is characterized by an unspecialized syndrome, though it also demonstrates anthropochorous tendencies, indicating dispersal through human activity.
