Abstract: An automated plant tissue proliferation system in which mature plants within a culture vessel are cut into a plurality of plugs using a die type cutter block. The cutter block is moved using a pick and place actuator to a work station where any extraneous nutrient media or plant material adhering to the sides of the cutter are removed using an indexed membrane sheet. A pair of opposed articulated wiping arms cause the membrane sheet to be wrapped around the cutter and pulled down vertically along its sides to remove the excess material. Thereafter, the cutter is indexed to deposit some fraction of the cut cells into a container having culture medium. Fluid pressure is used to eject material from the appropriate cells onto the media material. A number of additional containers are indexed into position with the cutter until all of the plugs of material are removed. the actuator and ejection system are so operated to distribute the plugs of plant material in a preselected array in a number of containers.

Abstract: Disclosed is a new and distinct Spathiphyllum variety distinguished particularly by rapid growth, denser appearance and compact growth when compared to related plants. Spathe color is initially white turning a light green hue past maturity.

Abstract: Disclosed is a new and distinct variety of Spathiphyllum which is particularly distinguished by having rapid growth and a propensity to sucker as compared to related plants. The plant is a selection from the cross Mauna Loa `Alice`.times.floribundum (seed parent) and wallisi (pollen parent).
