“…Interestingly, those few Drosera species which have scented leaves altogether have non-perfumed flowers. On the other hand, in those Drosera species that have perfumed flowers (see Fleischmann et al 2007;Gibson 2013;Lowrie 2013), I could detect no evident odor from the leaves. Both are reasonable, to separate pollinators from prey, which will be either attracted to the traps or the flowers by visual signals or scent, or vice versa.…”

The use of scented traps for prey attraction has been reported from a few genera of carnivorous plants: most prominently in the pitcher plant genera, where a sweet honey- or fruit-like scent is detectable to the human nose from the pitchers of some populations of Sarracenia flava, S. alata, S. rubra, S. oreophila, S. leucophylla, and S. minor, certain species of Heliamphora (a sweet, honey-like scent is produced from the nectar-spoons of H. tatei, H. neblinae, and H. chimantensis, while the pitchers of H. sarracenioides produce a notable chocolate-like odor when growing under natural or favorable conditions), and the pitchers of some species of Nepenthes. Interestingly, the Venus Flytrap Dionaea also has been discovered to attract prey to its traps not only by the vivid coloration, but also by producing scented volatiles.

“…However, a number of plants including Sedum spp., Gentiana spp., Veronica spp. (Nakanishi 2003) and at least three other sundews, D. felix, D. kaieteurensis, and D. solaris (Fleischmann et al 2007) employ this strategy to disperse seeds.…”

The Drosera of the subgenus Bryastrum, commonly referred to as pygmy sundews are unique to the genus in that all bar one produce vegetative clonal propagules known as gemmae. These gemmae are thought to be dispersed via a novel adaptation known as a splash-cup, but little is known about its effectiveness or other strategies employed by the plants. In this preliminary study, the splash-cup was tested and its effectiveness measured. The role of the stipules, which form the walls of the splash-cup were also examined along with other features of the plants’ architecture. The splash-cup was found to play a critical role in gemmae dispersal while the theory that the stipules perform as spring-loaded catapults was unsupported. Additionally, gemmae were found to either sink or float depending on the taxon. Observational evidence is provided which suggests the structure of a gemma plays a significant role in the success of each taxon in its preferred habitat.

“…40 species are currently recognized to occur in South America (Gonella et al 2015, Gonella et al in prep.). In the Neotropics, the genus is usually found in open vegetation types growing in nutrient-poor sandy soils, with two main centers of diversity: the Espinhaço Range in eastern Brazil and the Guiana Highlands on the border between Venezuela, Guiana and Brazil (Duno de Stefano 1995;Fleischmann et al 2007).…”

Nas muitas curvas sinuosas que a vida dá é certo que encontremos obstáculos, alegrias, tristezas, quiçá até mesmo uma espécie nova no Facebook, mas nenhum desses achados é mais valioso que uma amizade verdadeira. Aos meus queridos Carol e Baladinha, dedico. ! ! Só a Natureza é divina, e ela não é divina... Se às vezes falo dela como de um ente É que para falar dela preciso usar da linguagem dos homens Que dá personalidade às cousas, E impõe nome às cousas. Mas as cousas não têm nome nem personalidade: Existem, e o céu é grande e a terra larga, E o nosso coração do tamanho de um punho fechado... Bendito seja eu por tudo quanto não sei. É isso tudo que verdadeiramente sou. Gozo tudo isso como quem sabe que há o sol.
