First records of and from Senegal (Selaginellaceae).

Background: The monogeneric family Selaginellaceae is made up of about 700 species distributed throughout the world, but the most concentrated part is in tropical and subtropical areas. According to the most recent infrageneric classification of the genus , six or seven subgenera can be recognised and perhaps 700 species. The genus is monophyletic, cosmopolitan, characterised by the presence of rhizophores, ligulated leaves and has a reniform adaxial sporangia with two type of spores (heterospory).

The flow-pressure plot: a new look on the patient-ventilator interaction in neonatal care.

Most modern neonatal ventilators have now a built-in flow sensor and, as a spin-off of their mechanical action, provide some information about lung function characteristics as compliance and resistance after computation of the flow and pressure signals. Additionally, respiratory graphics as volume-pressure and flow-volume plots can be displayed. In clinical practice, however, they are rarely used to refine the ventilator setting.
