Then we have Don, whose description is, as usual, based upon the Prodromus 
account. 
A. amoena (Wendl. Diss. no. 8. t. 4.) phyllodia oblong, tapering much at the base, 1-nerved, bearing 
1-3 glands in front on the upper margin ; heads of flowers racemose ; flowers 5-cleft. Native of New 
Holland. Very like the following species (A. myrtifolia), but differs in the racemes being one-half shorter 
than the phyllodia. Petals 5, distinct. Ovary tomentose. The plant under this name in Sieb. pi. exsicc. 
nov. boll. No. 452 differs from Wendland’s in the phyllodia being scarcely margined, and only furnished 
with one gland in front on the upper margin, although perhaps the same. 
Pleasing Acacia. FI. April, June. Clt. 1820. Shrub, 4 to 6 feet. (Don’s Gen. Hist. Dichlamydeous 
Plants, Vol. 2, p. 405.) 
Here is Bentham’s description, and it will be observed that he attributes 
specimens collected on the Lachlan and Macquarie Biversby Fraser and Cunningham 
(presumably on Oxley’s Expedition of 1817) to this species. These are comparatively 
dry country localities, whereas the others recorded for A. amoena are coastal mountain 
regions; the plants should be further examined. It will also be observed that these 
specimens are “ ovario glabriusculo.” 
A. amcena (Wendl., Diss. 16. t. 4.), glabra, ramulis angulatis, phyllodiis oblique lanceolatis 
rectiusculis uncinato-mucronatis basi longe angustatis marginatis plerisque 2-3 glanduliferis nitidis 
uninerviis venis tenuibus, racemis phyllodio subbrevioribus, capitulis parvis 8-12-floris glabris, ovario 
glabriusculo. Phyllodia l. 1 ,—2J pollicaria, glandulis saepissime 2, a basi et inter sese distantibus. Near 
the Lachlan and Macquarie Rivers, Fraser, Cunningham. (Bentham, in Hooker’s London Journal of 
Botany, Vol. 1, 356.) 
Then Bentham describes it in the following words : — 
A tall shrub, quite glabrous, young branches pubescent. 
Phyllodia obliquely lanceolate or oblaneeolate, straight or falcate, obtuse, or with a small 
recurved point, much narrowed towards the base, not very thick, 1-nerved, with nerve-like 
margins, and more or less distinctly veined, with 1,2, or 3 often prominent distant marginal 
glands, 1$ to 2± inches long on the flowering shoots, longer on the barren branches. 
Racemes usually shorter thon the phyllodia, with several small globular heads of about 8 to 12 
flowers, mostly 5-merous. 
Sepals short, broad, usually separating when the flower is fully out. 
Petals 5, distinct, smooth, with prominent midribs. 
Pod flat, straight or curved, with nerve-like margins, several inches long, 3 to 4 lines Void, not 
contracted between the seeds. 
Seeds ovate, longitudinal; funicle dilated and reticulate from near the base, very long, 
extending round the seed, returning on the same side and bent back a third time, encircling 
the seed in a triple-fold, and thickened at the end into a fleshy aril, two-thirds the length of 
the seed. (B.F1. ii, 366). 
Bentham adds,— 
The funicle completely encircling the seed a third time does not occur in any other species which 
I have been able to observe, and is in all the seeds I have examined of A. aintcna; it remains, however, to 
be ascertained whether it is really so constant a character as it appears to be. (B FI. ii, 367). 
Bcntliam’s description, as far as the pods and seeds are concerned, applies 
both to A. rubida and to A. amcena. 
The first part of the description applies to Wendland’s plant, and could have 
been compiled largely from Wendland’s figure. Bentham had not (to his know¬ 
ledge) seen the pods of A. rubida. 
Botanical Name.— Acacia, already explained. (See Part XV, p. 104) ; 
amcena, Latin, signifying “delightful to the eye,” in one word, “ pretty.”
