380 NOTES ON THE HYBRIDISM OF THE GENUS BRACHYCHITON. 



name Br achy chiton populneo-acerifolium might be chosen for this 

 highly interesting cross-production, the preponderance of resem- 

 blance being rather with.5. acertfolium than with B. populneum. 



It is worthy of remark, that from the whole extensive order of 

 Sterculiacem only one instance of spontaneous hybridisation is on 

 record, Mr. 0. Tepper having discovered a cross between 

 Lasiopetalum Baueri and L. discolor in South Australia. In the 

 recent special work by Dr. W. 0. Foske (Die Pflanzen 

 Mischlinge, 1881) mention is however made of artificial crosses 

 among the South African Maker mas, and doubtless in that genus 

 as well as in Uermannia natural bastards could be found also. 



This seems an apt apportunity to state that Br achy chiton 

 acerifolmm has been traced recently by Mr. W. Biiuerlen as far 

 south as Shoalhaven, where this assiduous collector gathered also 

 the following plants, which were not proviously noticed so far 

 south: Philotheca aitstralis, Sida rhombifolia, Poranthera ericifolia, 

 Elatostemma reticulatum, Pennantia Cunninghami, Yitis clematidea, 

 Pultenaea elliptica, Hovea linearis, Zornia dipliylla, Ceratophylhtm 

 yummiferum, C. apetalum, Melaleuca styp>helioides, Kunzea capitata, 

 Euyenia myrtifolia, Trachymene linearis, Actinotus minor, Cono- 

 spermum tennifolium, Cassinita quinqueforia, Goodenia heterophylla, 

 Candollea laricifolia, Ghloanthus Stoechadis, Clerodendron tomentosum, 

 Tricoryne simplex, Aneilema acuminatum, Gymnostachys anceps, 

 Paspalum scrohiculatum.
