 Collection. 



Series YI. Uninerves.— Phyllodia vertically flattened, either narrow 

 and obtuse or with a short oblique or innocuous point, or broad and obtuse 

 acute or rarely pungent-pointed, with 1 central or nearly marginal nerve, or 

 very rarely 2-nerved. Flowers in globular heads, either on simple axillary 

 peduncles, solitary or in pairs or clusters, or several in axillary racemes. 



This series comprises all the species with l-nerved phyllodia and ^lohular flower-lieads, 

 where the phyllodia are not continuous with the stem as in the Alatts and Continua, nor 

 narrow aud pungent as in the Fuiigenies, nor terete or tctragouous as in the Calamiformes, 

 nor whorled as in the Brimioidece, The nerve is usually central or nearly so, with the small 

 veins, when conspicuous, pinnate or reticulate ; where the nerve is exccntrical or near the 

 lower juargin, one or two of the principal veins will sometimes arise from near the base on 

 the upper side, hut diverge from the midrib and are not continued to the end of the phYllo- 

 dium as in the Plurinerves. A. vernicifiua, and a very few others, have most or some of 

 their phyllodia 2-nerved as iu the %-\itxst\ Fhirlnerves^ hut are placed among the c;n- 

 nerves^ either because the second ucrvc is very inconstant or from their close affinity to 

 species where it does not exist. 



A. Spinescentes. — Eigid shrubs with spiiiescent branches. Phyllodia 

 small, usually narrow, not pungent, without marginal glands. Stipules 

 minute or none (except sometimes m A. scabra). Peduncles 1-headed. 



Spiiiesceut braaches occur also in a very few of the Armata aud of the Tiiangnlares of 

 the preseut series, in some of the Punyentes, and in A. amblygona among Plurinerves. 



72. A. scabra, BeutJi. in Lmna;a, xxvi. 605. A shrub with rigid di- 

 varicate spinescent branches, more or less scabrous-pubescent. PhylloJia 

 linear-oblong, very oblique or falcate, obtuse or with a small recurved point, 

 about \ in. long, 1 to 2 lines broad, rather thick and l-nerved, scabrous-pu- 

 bescent or at length glabrous. Stipules small, setaceous or almost spinescent. 

 Peduncles about as long as the leaves, bearing each a globular head of aMve 

 30 flowers, mostly 5-merou3. Calyx thin, the lobes obtuse and cilia e, 

 readily separating into spathulate sepals, fully half as long as the corolla. 

 Petals thin, with slightly prominent midribs. Pod (not seen ripe) narrow- 

 linear, flat, with thickened nerve-like margins. 



W. Australia, Brummond, 2nd Coll. n. 162. Allied on the one baud to the follow- 

 ing species, on the other to some of the narrow-leaved Armatce. 



73. A. nodiflora, Bmlh, in Limum, xxvi. C21. A shnib with long 



rigid virgate branches and divaricate branchlets, often spinescent ^"^^^^^ j 

 glabrous. Pliyllodia clustered on the old nodes, linear, oblique or talcai .
