DESCRIPTION. 



LXVIII. E. uncinata, Turczaninow. 



Following is the original description : — • 



Eucalyptus uncinata. Caule, ramis, ranmlisque teretibus cortico fusco ; foliis alternis petiolatis 

 lineari-lanceolatis, glauc r sceutibus, subpellucidoi-punctatis marginatis, basi longe attenuatis, apice in 

 acumen uncinatum product-is ; capitulis multifloris pedunculatis, inferioribus remotiusculis, superioribus 

 in racemum densum collectis ; pediinculis petiolos subaequantibus ; pedicellis fere nullis ; cupula turbinata 

 tereti aut vix angulosa ; operculo conico obtusiusculo cupulam subacquante slaminibus exsertis (albidis). 

 Alabastia pai-va, magnitudine illorum E. rdbustae, folia 2-3 poll, longa, latitudine majore 2h lin. non 

 excedente. Drum. 3, n. 66. Turcz. in Bull. Soc. Nat. Moec, xxii, pfc. 2, p. 23 (1849). 



It will be observed tbat the type is Xo. 06 of Dmmmond's third collection. 

 This is repeated, word for word, in Walpers 1 Annates Botanices Systematica, 

 ii, 620 (1843). 



It was then described by Bentham, in B.1T. iii, 216, and afterwards figured 

 and described by Mueller in the " Eucalyptographia." The narrow-leaved specimen 

 at the right of the plate is E. teptophytla, Miq. (E. oteosa, F.v.M. ; var. leplophylla, 

 E.v.aT.) — in other words, the narrow-leaved form of E. uncinata. I have heard 

 doubts expressed as to the validity of E. uncinata as a species, but such doubts are 

 quite unnecessary. It is, however, not a very well-known species even yet, being 

 confused with other Mallees. 



E. uncinata is one of the species in which the juvenile form of foliage often 

 remains side by side with the mature foliage. The leaf is often hooked (uncinate), 

 but this is by no means a universal character. 



The anthers are not terminal truncate like those of E. melliodora, paniculala 

 and others, but (see Tig. lb, Plate 62) of an allied and peculiar shape, for which I 

 propose the name semi-truncate. 



The kink in the filament is well exhibited in this species and does not occur 

 in the flowers of many others. 



VARIETIES. 



Bentham suggests three varieties : — 

 1. Var. latifolia, Benth., Drummond, 1th Coll., Xo. 70 (B.Fl, iii, 216). 



I have had a drawing prepared of Drummond' s specimen in the Cambridge 

 Herbarium. A sufficient portion is figured at 2a of Plate 02. It is not in 

 ripe fruit. 



I collected specimens from the Kalgan Plains, north of the Kalgan River, 

 Western Australh, which match Dmmmond's specimen in every detail. It seems 

 to me a stunted, precocious form of the type, with, on the same shrub or clump of 

 shrubs, leaves of the normal width and leaves broad, and with the pedicels absent or 

 nearly so. These shrubs flowered while the leaves were in the broad opposite-leaved 

 state. Specimens are figured at 3a, 35 of Plate 62.
