I learned some new hollies yesterday, and not a spiny or serrated leaf margin among them. Here is Ilex litseifolia, which at least did have clusters of tiny flowers. Wikipedia says Ilex flowers have 4 petals. The flowers in the first flower photo here have five petals, but the other photo shows four-petalled flowers. Accession: 032526-0607-1993 The flowers are not yet open on the Ilex elmerrilliana. Accession: 024481-0437-1984 Thanks to Andy Hill for the ID of this Ilex pedunculosa, (longstalk holly), wild collected in Japan by the staff at Kyoto Takeda Herbal Garden in 1984. Just single flowers, with four, five or six petals. This is next to the bridge at Decaisne and Forrest.
