About plant names...

Pencil tree is a native of northeastern, central and southern Africa. It is also found in China, Indonesia, India, and the Philippines. It is not native to North America, but has become naturalized in some areas.

Identification: Branches are smooth, cylindrical, green, about the diameter of a pencil. (Branches may also have orange-red tips.) Plants are up to 20' (6.1 m) high. There are no spines. Leaves are small, about ½" (1.3 cm) long and less than ⅛" (3.2 mm) wide. They fall off early, so usually the stems appear naked. Flowers are pale yellow and inconspicuous.

Edibility: Poisonous Skull & Crossbones The milky sap that oozes from any broken part of this plant causes dermatitis and severe pain in some. It can cause extreme pain and induce temporary blindness, lasting several days, if it comes in contact with the eyes. If you get any in your eyes, flush them with water for at least 15 minutes, then seek immediate medical attention. Deaths have been recorded from ingestion.
