Polyspora chrysandra (Cowan) Hu ex B.M.Barthol. & T.L.Ming

This species was discovered by Forrest in 1912 west of Tengyueh near the frontier between Yunnan and Burma; he appears to have introduced it in 1917 under F.15559, collected at 9,000 ft on the western flank of the Tali range, where it makes a large shrub 20 to 30 ft high. First described in 1931, this species differs from P. axillaris chiefly in its smaller leaves (up to about 4 in. long) and smaller flowers (about 2 in. or slightly more wide). It has been so little tried out-of-doors that it would not be possible to state whether or not it is less tender than P. axillaris; it is likely, in any case, to be bud-tender. In the Edinburgh Botanic Garden it is grown under glass and has never survived when planted outside. There was a specimen in the old Temperate House at Wisley which flowered well in January and February. Propagation is by cuttings of nearly ripened wood. Bot. Mag., n.s., t. 285.
