\Oth June 1827. 

 Acacia lunata. 



Loddig. Bot. Cab. t. 384. 



A. lunata ; phyllodiis falcatis, basi vix attenuatis, oblique mucronatis, uni- 

 nerviis, margine antico uniglandulosis ; pedunculis racemosis, axillaribus, 

 phyllodios sequantibus ; capitulis numerosioribus, paucifloris ; floribiis 

 6-fidis. 

 Description — Shrub free growing. Branches scattered, spreading, slen- 

 der, smooth, angular. Phyllodia falcate, mucronate, glaucous, 1^ inch 

 long, \ of an inch broad, having a distinct single rib not quite in the 

 centre, veins very obscure ; as the branches spread out nearly at right 

 angles, the phyllodia on the lateral branches turn towards the upper 

 side, but on the upright shoots they spread on all sides. Peduncles axil- 

 lary, about the length of the phyllodia, sometimes a little longer, often 

 rather shorter ; pedicels simple. Flowers capitate, capitula numerous on 

 each peduncle, generally four flowers in each head. Calyx 5-phyl- 

 lous, phyllse ovate, pointed, adpressed, corolla 5-cleft ; tube campa- 

 nulate, Umb spreading, segments lanceolate. Stamens very numerous, 

 filaments very slender, anthers rounded. Style longer than the fila- 

 ments ; germen lateral ; the whole capitulum of a deficate and beautiful 

 yellow colour. 

 Seeds of this very elegant species were received from Mr Fraser from New 

 Holland, under the name of Acacia acinacifolia, in 1821. We have re- 

 marked, as stated by Messrs Loddiges, that it never produces fruit in 

 our greenhouses. 



Acacia mucronata. 



Banksia integrifolia. 



Br. Trans. Linn. Soc. vol. x. p. 206. ? 



Description — Trunk erect. Bark dark and cracked. Branches at first 

 erect, ultimately spreading, covered with soft, yellowish pubescence when 

 young. Buds in whorls, but generally all, excepting one or two, abor- 

 tive. Leaves petiolated, subverticelled or scattered, ligulate, coriaceous, 

 dry, stiff, undulated, green and naked above, below covered with white 

 tomentum, through which many small reticulated veins appear, when 

 young covered with yellow tomentum on both sides, sinuato-serrated, 

 occasionally entire, serratures mucronate, middle rib prominent behind. 

 Flowers terminal, head 2-3 inches long, less than half the length of the 

 leaves, which are generally crowded at its base. Calyx silky. 



We have a plant which has not yet flowered, but which I can consider 

 only a variety, which is more vigorous in its growth, the trunk swollen 

 into joints, the branches more erect, the leaves more decidedly verti- 

 celled, more of them entire, and many of them lanceolate, having evident 

 nearly transverse primary veins, the pubescence on the young shoots 

 being red-brown. 



Raised from seeds sent by Mr Fraser from New Holland in 1819. 



Cactus heptagonus. 



Cycas circinalis, mas. 



This plant, whose stem is 44 feet high, nearly cylindrical, and 6 inches 

 diameter at the base, has flowered for the first time with us this spring. 

 Its appearance differs from the figure given by Achille Richard, in the 

 catkin being sessile, cylindrical, less compact, the scales much shorter, 

 more dilated at their outer extremities, so as to give them a deltoid or
