Botanical Identification
Ecology
The ecology of Drymaria cordata is characterized by its remarkable adaptability to diverse environmental conditions and a broad altitudinal distribution. This species thrives across an expansive elevational range, spanning from sea level (0 m AMSL) up to high-altitude regions reaching 4300 m AMSL. Its habitat preferences are exceptionally varied, allowing it to colonize a multitude of ecosystems. It is frequently found in anthropized areas (Área Antrópica) and open landscapes such as Campo de Altitude, Campo de Várzea, and Campo Limpo. Furthermore, it integrates into complex forest structures, including Floresta Ciliar or Galeria, Floresta de Igapó, Floresta de Várzea, Floresta Ombrófila (Rainforest), and Floresta Ombrófila Mista, as well as specialized coastal environments like Restinga.

Genetics
The genetics of Drymaria cordata are characterized by a complex chromosomal structure that suggests evolutionary processes such as polyploidy or hybridization. The plant exhibits varying chromosome numbers, specifically documented at 24 and 36, which indicates significant genomic diversity within the species. This variation in the diploid or polyploid sets suggests a flexible genetic makeup that may contribute to its ability to adapt to diverse environmental conditions. Such chromosomal fluctuations are central to the plant's cytogenetic profile, reflecting a dynamic genome that plays a crucial role in its reproductive biology and evolutionary lineage.
- Chromosome number :
- 24, 36
Life history
The life history of Drymaria cordata is characterized by a variable lifecycle, as it can function as an annual, biennial, or perennial plant depending on environmental conditions and habitat stability. This flexibility allows the species to adapt to diverse ecological niches, ranging from disturbed soils to more stable, moist environments. The plant typically begins its life through seed germination, often colonizing open spaces where light is available. As it matures, it develops a low-growing, creeping habit, utilizing stolons or rhizomes to spread vegetatively, which assists in both rapid colonization and long-term persistence. Throughout its life, the plant undergoes seasonal growth cycles, producing small flowers that facilitate sexual reproduction via seed dispersal, while its ability to transition between different lifecycle durations ensures its survival across fluctuating seasonal patterns.
- Lifecycle :
- annual
Morphology
The morphology of Drymaria cordata is characterized by its growth form as a non-woody herb and forb. This terrestrial plant is independent, functioning without a parasitic relationship, and it grows as a self-supporting species rather than as a liana or vine. In terms of its stature, the plant typically reaches a height ranging from a minimum of 0.25 m to a maximum of 1.5 m, with an average plant height of approximately 1 m. As a terrestrial organism, it does not exhibit epiphytic or aquatic habits, maintaining a consistent growth pattern suited for land-based environments.

Physiology
The physiology of Drymaria cordata is characterized by a C3 photosynthetic pathway, indicating a standard carbon fixation process typical of many shade-loving herbaceous plants. The morphological dimensions of its foliage reflect a specific physiological scale, with leaf lengths ranging from a minimum of 0.5 cm to a maximum of 2.5 cm, while leaf widths vary between 0.5 cm and 3 cm. Furthermore, this species does not function as a nitrogen fixer, meaning it relies on the availability of nitrogen within the soil rather than through symbiotic relationships with diazotrophic bacteria.

- 2.5 cm
- Leaf length min:
- 0.5 cm
- Leaf width max:
- 3 cm
- Leaf width min:
- 0.5 cm
- Nitrogen fixer :
- no
- Photosynthetic pathway :

Reproduction
The reproduction of Drymaria cordata is characterized by the production of small capsules, which serve as the primary fruit type. These fruits are dehiscent, meaning they split open at maturity to release the seeds. The fruit dimensions are relatively minute, ranging from a minimum length of 0.15 cm to a maximum of 0.25 cm. The seeds produced within these capsules are characterized by a seed length that varies between 1 mm and 1.5 mm. In terms of mass, the seeds are extremely lightweight, maintaining a consistent mean, minimum, and maximum seed mass of 0.00019 g. The dispersal syndrome for this species is classified as unspecialized, suggesting that the seeds are spread through general environmental processes rather than highly specific biological or mechanical vectors.
