XXVIII. E. virgata, Sieb. 



In Sprengel's Cur. Pod., 195 (1827). 



I DESIRE to bring the following names under review: — 



E. rigida, Hoffmannsegg (Verz. PfL Nachtr. ii, 114, 1826). 



E. virgata Sieb. (in Sprengel's Cur. Post., 195, 1827). 



E. stricta, Sieb. (in Sprengel's Cur. Post., 195, 1827). 



E. amhigua, DC. {Prod, iii, 219, 1828). 



E. obtusiflora, DC. [Prod, iii, 220, 1828). 



E. fraxinoides, Deane and Maiden {Proc. Linn. Soc. N.S.W., 1898). 

 All these plants form a series with narrow* suchers. Compare E. Luehmanniana. 

 I will bring forward evidence to establish the following nomenclature: — 

 E. virgata, Sieb. 



1. Var. obtusiflora. Maiden. 



Syn, {a) E. obtusiflora, DC. 

 {b) E. rigida, E.Br. 



(c) E. rigida, Sieb. [E. rigida, Hoffmg., is indeterminable). 

 {d) E. piperita, Sm., var. pauciflora, DC, in Prod, iii, 219. 



2. Var. stricta. Maiden. 



Syn. (a) E. stricta, Sieb. 

 {b) E. ambigua, DC. 



3. Var. fraxinoides, Maiden. 



Syn. E. fraxinoides, Deane and Maiden. 



4. Var. triflora, Maiden. 



The name Eucalyptus rigida. 



E. rigida was the name originally given by Robert Brown (in 1800-5) to specimens 

 gathered by him on the South Head road (part of Sydney). I have seen these specimens 

 in the British Museum, and in other herbaria. 



Then Hoifmannsegg published a plant under the name E. rigida in the year 1826, 

 in the following words: — 



(432) Eucalyptus ri'jida. E. caulc ramisque teretibus, foliis rigidis duris, infimis scssilibus oppositis 



ovatis subcordatis obtusis, suporioribus sensim pctiolatis sparsis lanccolatis acutis subapiculatis 



Hab. in Austral. 



* I have already uttere;! the dictum that everything is variable in Eucalyptus. Taken as a general statement, it 

 is perfectly true that plants of tlie virgata scries have narrow suckers. But we may have suckers so broad that it becomes 

 difficult to separate them, on this ground, from LuehmanniatM, e.g., certain specimens of E. virgata, var. obtusiflora, from 

 South Head, Port Jackson (R. H. Cambagc). 



In the present Part I have already referred to the variation in width of sucker.^ of E. acnvmioides.
