nost part }-cllo\vish or copper-coloured ; the round ripe fruits, on long 

 talks, appear all over the crown. In many places the fresh green of 

 oung shoots glistens through the yellowish foliage. Pileostigma acidum 

 irescnts a similar appearance. Maniltoa gemmipara is dark green over 

 he greater part of its crown, but has a few white young shoots drooping 

 IS in a flaccid condition. Resembling it are Jonesia declinata and 

 ynometra sp. Amherstia nobilis exhibits all possible conditions, from a 

 )ud that is resting to one that hangs flaccidly ; likewise from a red young 

 hoot to one that is hardened and green ; also all stages of inflorescence 

 re present ; but fruit is absent, being never formed here. The leafy crown 

 f Jonesia minor resembles that of Amherstia ; on the stem one sees 

 iiflorescences in all stages, from the earliest bud to the mature orange- 

 ellow umbels, and fruits from the moment they protrude beyond the 

 orolla-tube to the o\er-ripe burst pods.
