Leptotes (plant) species that have more rounded flowers with petals and sepals that are wide open and flatter. The leaves are shorter wrinkly leaves, generally very dark green or purple colored. The species of this group often have only one or two flowers on each inflorescence. Four of them are very similar and sometimes difficult to distinguish. Leptotes (plant) Leptotes, abbreviated Lpt in horticultural trade, is a genus of orchids formed by nine small species that grow in the dry jungles of south and southeast Brazil, and also in Paraguay or Argentina. They are small epiphytic plants of caespitose growth that sometimes
Calyx of Held principal neuron with a distinct morphology: branching of the calyx allows the creation of second- and third-order networks. Each branch establishes a connection with the principal neuron, establishing a large number of active zones. This is unusual for synaptic terminals in the brain, as most create a single active zone. Each calyx contains anywhere from 300 to 700 active zones, and in each of the active zones there are about 100 glutamate-containing vesicles with about 3 docked vesicles at a time. These vesicles are large, consistent with the findings regarding quantal size in other adult synapses. Dense-core vesicles, usually containing
