XVIII. A. Jutsoni 11. sp. 



Frutex, ramulis angulatis v. fere teretibus. Phyllodiis lineari- 

 tetragonis, rigidis, leniter curvatis mucrone breve pungente, 6 5 - 

 8 cm. longis, utroque latere striatis, junioribus partibus viscidis, 

 cum costis parallelibus, brevibus pilis tectis. Floribus in spicis 

 brevibus ovoidiis densis, breviter pedunculatis, ca. 7 mm. longis. 

 Calyce turbinate-, pilis paucis sparsis disperse-. Petalis calycem ca. 

 triple- superantibus, sub lobis cohaerentibus. Legumine non 

 viso. 



Apparently an erect shrub, branchlets slightly angular 

 or nearly terete. Pbyllodia linear-tetragonal, rigid, slightly 

 curved, with a short pungent point, 6*5-8 cm. long, each 

 of the sides uniformly exhibiting a rounded rib, giving the 

 phyllode a grooved appearance, the young growth viscid, 

 but with parallel ridges covered with short white hair, the 

 mature phyllodes covered with a very short tomentum. 



Flowers in short ovoid dense spikes, shortly pedunculate, 

 about 7 mm. long. Flowers mostly 5-merous. Oalyx 

 turbinate, sprinkled with a few scattered hairs, about a 

 third the length of the corolla. The petals united immedi- 

 ately below the lobes. Pistil small and smooth. Pod not 

 seen. 



The type is from Comet Vale, near a railway station 63 

 miles north of Kalgoorlie (John Thomas Jutson, Nos. 160 

 and 49 of December, 1916). 



The following specimens belong to this species, although 

 their phyllodes are, for the most part, less tetragonal r 

 sometimes becoming almost terete, with striae. 



a. Elder Exploring Expedition, Camp 54, Victoria Desert, 

 17th September, 1891 (R. Helms, No. 14). "On sand." 

 Latitude 29° 33' 25", Longitude 124° 50', height 1,100 feet. 



b. Phyllodes resinous all over. Ooolgardie (L. O.Webster^ 

 year 1898).
