DESCRIPTION. 



Following is the original description : — 



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

 lanceolatis utrinque attenuates acuruinato-mucronatis : mucrone interdum uncinato, marginatis pellucido- 

 punctatis ; utnbellis lateralibus 3-6 floris ; pedunculis angulatis petiolo paulo brevioribus ; cupulis 

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

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

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

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

 Phys.-Math. Acad. Petersb., 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(5). St. Petersburg. Academie imperiale 

 des sciences, (bulletin de la classe physico-mathematique. 1 vol., 1-17, 1842-59 

 (1843-59). 17 v. 4° 



(O )! 



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

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

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



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

 physico-mathematique. Vol. 1-9, iv. 1849-75 (1853-76). 9 v. 8°." So that, 

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

 even than 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 eucalypts are usually more characteristic than the terminal ones. When 

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

 requires 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,
