1 Leaf blade base cuneate, abaxial surface with gray - white indumentum; corolla magenta - rose.

2 Basal leaf blade oblong or elliptic, truncate or cuneate at base.

3 Leaf blade base broadly cuneate to rounded, margin obtusely serrate ; drupe and endocarp ellipsoid to oblong.

4 The afferent neurons from cuneate nucleus, gracile nucleus, nucleus of spinal tract of trigeminal nerve, nucleus of solitary tract mainly located below the level of obex.

5 Leaf blade base rounded or broadly cuneate; fruit rugose when mature.

6 The projections from the external cuneate and the dorsal column nuclei to cerebellum in 44 rats were examined by means of HRP.

7 Leaves usually double serrate, base broadly cuneate to cordate; plants more than 30 cm tall.

8 Petiole 4-6 mm; leaf blade elliptic to oblong-elliptic, base cuneate to broadly cuneate,[www.Sentencedict.com] apex obtuse to subrounded and with a retuse tip.

9 The shape of leaf margin in transverse section can be divided into arcuate and cuneate.

10 Medio-Iaterally, the cervical projecting cells were located chiefly at the junctional area between the gracile and medial cuneate nuclei and at the ventromedial part of the latter.

11 Results The neurons labelled by HRP were found in bilateral locus coeruleuses, and there was no obvious difference between the groups of gracile and cuneate nucleus.

12 The high density nuclei consist of the pontine nuclei, inferior olivary complex and so on which have connections with cerebellum, cuneate nucleus, superior olivary nucleus and abducent nucleus.
