1104 Syringa 1104 Syringa 1104 Syringa, provisional designation , is a dark background asteroid from the central regions of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 9 December 1928, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was named after the flowering plant "Syringa" (lilac). "Syringa" is a non-family asteroid from the main belt's background population.

Rheum (plant) represented by about 60 extant species. Among species found in the wild, those most commonly used in cooking are the garden rhubarb ("R. rhabarbarum") and the so-called false rhubarb ("R. rhaponticum"), which is actually a true rhubarb. The many varieties of cultivated rhubarb more usually grown for eating are recognised as "Rheum" × "hybridum" in the Royal Horticultural Society's list of recognised plant names. The drug rheum is prepared from the rhizomes and roots of another species, "R. officinale" or medicinal rhubarb. This species is also native to Asia, as is the turkey rhubarb ("R. palmatum").
