seeds could be made to keep for much longer periods than found 

 here. Seed of E. Baileyana, after 23 years, failed to germinate; 

 and others that also gave no result were E. lactea (19 years), E. 

 qiiadranyulata {\%), E. sideroxylon (11), E. melliodo7'a (I'.l), E. 

 Miielleri (\Q), E. tet'minalis (12), E. angophoroides {\\), E. vitrea 

 (12), E. dextropineailS and 18), E. Dawsoni{lS), E. hcemastoma 

 (16), E. f?\ixinoides (IS), E. acacicpformisi^W)^ E. LiLehm<i7iniana 

 (19), E.fastigata (13), E. pyri/ormis {'21), E. albe7is (12), and E. 

 tessellaris (12 years). On the other hand, E. Risdoid {^ years), 

 E.carnea{\\), E. Stuartia'na(lO), E. ovali/olia{\2), E. Woollsiana 

 (8), E. pendnla (1\), E. hemilampra(9), E. pjinctata (\^), E.

 E. Eosfiii(7 ), E. pulvenilenta(lO), E. Baeuerleni{lO), E Macarthiiri

 Morrisii{\\), E. aggregata(\3), E, de(dhata{\2), E. marginata{l), 

 E. ajfinis{l0), E. hcemasto^na var. micranthailQ), and E. obliqua 

 (18 years), all germinated after such prolonged periods of pre- 

 servation. That seeds of E. obliqua and E trachyphloia should 

 keep 18 years, and E. Jwrnastoma var. 7nicrantha and E. pu7icta(a 

 16 years, is a remarkable testimony to the power of the seeds of 

 this genus of withstanding dessication for prolonged periods. 



Much has been written, especially by foreign observers, as to 

 " the variability of Eucalyptus under cultivation." I have not 

 found this to be so, even after growing seedlings of the same 

 species from widely separated localities. They have invariably 

 come true. We may get some fluctuations or slight departures 

 from the normal, but when species have been botanically identified 

 by an expert, who knows the Eucalypts, this supposed variability 

 has not been found to occur. Many of the mistakes have been 

 due to trusting to the vernacular names of collectors, who had a 

 very imperfect botanical knowledge. Again as to hybridism, I 

 have been keenly on the alert to discover instances of this, but, 

 after examining thousands of seedlings from different species, I 

 have not seen one single instance of it so far. 



Although the seedlings of many species differ so markedly 

 from one another, that they could be detected at once, 1 have
