with the type of var. ferjiandeziana by HiTCFICOCK. Lot 3 ought to correspond 

 to 5. inacratJiera Phil. ^.nA fernandeziana Phil 1873 non Steud 1854. But I do 

 not see how we could segregate species or even tolerably good varieties. The 

 Juan Fernandez form is variable enough to cover the entire range of variation, 

 Bertero no. 800 and the type o{ fernandeziana Phil, being the extremes. Well 

 developed anthers were observed in W'erdermaxx no. 331, measuring 2 mm in 

 length. Cleistogamous flowers with only one fertile but small anther were de- 

 scribed 1. c. 97. 



Pubescence of leaves and nodes, length of blade and degree of convolution 

 vary a great deal, and so does the length of awn. Under 5. neesiana taken in 

 a broad sense, 5. niaiiicata Desv. and longiflora Steud. seem to fall. 



2. Piptochaetium bicolor (Vahl) Desv. Skottsb. 3. 98. 

 Parodi (2) referred the island plant to var. typicinn.

Inspired by a communication from Dr. LVMAX B. Smith, Looser (i i. 299) 

 judges Hesperogreigia to be identical with Greigia, but he does not quote my 

 paper on these genera. I think I have given good reasons for the generic 

 separation from Greigia as typified by G. sphacclata (R. & P.) Kegel, but I have 

 never claimed it to be endemic in Juan Fernandez. To Hesperogreigia belongs 

 G. Lajidbeckii Phil. (//. Laiidbeckii (Phil.) Skottsb.), perhaps also other species 

 which I had no opportunity to examine. 



30. Ochagavia elegans Phil. Skottsb. 3.1 10. 



Harms 1. c. 109 keeps Ochagatna and RhodostacJiys as separate genera, 

 whereas Mez 1. c. 204 unites them under the former name. I discussed this 

 question with HARMS, who wrote: "Die Gattung Ochagavia Phil, scheint mir 

 gut zu sein und sollte niclit mit Rhodostachys vereinigt werden." j\Iez remarks 

 that 0. elegans is not in cultivation, but I raised it from seeds in 1918 and 

 again in 1919. It is a vigorous grower in a temperate house and cuttings were
