DESCRIPTION. 



Following is the original description : — 



49. Eucalyptus calycogona (Drum. 5, n. 184), E. glabra ; ramis teretibus ; folii.s alternis lineari- 

 lanceolatis utrinque attenuatis acuminato-mucronati.s : mucrone interdum uncinato, marginatis pellucido 

 punctatis ; umbellis lateralibu.s .3-6 floris ; pedunculis angulati^ petiolo paulo brevioribus ; cupulis 

 obpyramidatis tetragonis, nigro-puactatis subsessilibus vel cum pedicello confluentibus, pedunculo 

 longioribus ; operculo conico laevi, cupula plus quam duplo breviore. E. foecundce, Schauer, cujus 

 operculum ignotum, stirps nostra aflinis est, sed folia minora, pellucida et cupula angulis 4 acutis marginata. 

 Filamenta alba. Capsula 4-locularis, cupula duplo brevior. Folia bipolUcaria, 2^ lin. lata. (Turcz., Bull. 

 Phys.-Math. Acad. Petersh., 10, 1852, p. 338.) 



The type is, as Turczaninow states, No. 184, of Drummond's 5th collection. 



I have not seen this publication ; I doubt if there is a copy in Australia, 

 and I am indebted to Kew for the extract. It is probably that quoted in Scudder 

 {Catalogue of Scientific Serials), "3707(iK St. Petersburg. Academie imperiale 

 des sciences. {Bulletin de la classe physico-mathematique. 1 vol., 1-17, 1842-59 

 (1843-59). 17 V. 4°." 



Mueller (" Eucalyptographia ") quotes the reference as " Turczaninow in 

 Melanges blologiques tires du Bulletin physico-mathematique de V academie imperiale 

 des sciences de St. Petersbourg, tome i, 417." 



Scudder, under No. 3707, gives (g) " Melanges blologiques tires du bulletin 

 p^iy.Kico-mathematiquc. Vol. 1-9, iv. 1849-75 (IS53-76). 9 v. 8°." So that, 

 according to Mueller, the date of Turczaninow's species is 1849, three years earlier 

 even tlian the date quoted by Kew. 



Leaves. — In E. calycogona and its varieties the venation of the lower leaves 

 is spreading ; the top or young leaves, are more penniveined. This is a matter of 

 considerable importance, and, speaking generally, it may be stated that the lower 

 leaves of cucalypts are usually more characteristic than the terminal ones. When 

 fragmentary, or small specimens arc alone available for examination or figure, one 

 re(|uires to be very careful to interpret the venation in consequence. I have referred 

 to the variation of venation in Eucalyptus at page 8, Part I.
