Affinities : As Professor Tate points out, its nearest affinity is with L. lino- 

 phyllus Fenzl., forma c. of Bentham, which I regard as the typical L. Unophyllutf. 



From herbarium specimens the plant appears to be an erect grower, whilst 

 its nearest ally is pendulous in the majority of cases. Sometimes the flower.s of 

 L. linophyllus are tetramerous, but the filaments are long and free at the top 

 with narrow anthers, not united for their entire length, with broad, 4-celled, almost 

 sessile anthers as in L. gibberulus. In these two characters it differs from all 

 the other Australian species. Its immature fruits are exactly like those of L. 

 Nestor S. Moore; the large orbicular bracts are similar to those of L. ferrugini- 

 florus W. V. Fitz. ; but the foliage of both species is totally different. It is in- 

 teresting to note that L. gibberulus has so far been recorded from Proteaceous 

 food-plants only. Professor Tate was of the opinion that it confined itself to 

 the Grevilleas but it has since been noted on Hakeas. 



Hosts. — Proteaceae: Grevillea striata R.Br., G. aquifolia A. Cunn., G. iiemato- 

 phylla F.V.M., G. junci folia. Hook, and Hakea leucoptera R.Br. 



Var. Tateii, n. var. 



Folia glabra, teretes crassa, nonnumquam rigida, apposita vel fascieulata 5 — -9 

 cm. longa. Alabastra graciles non tarn robusta quam in forma typiea. 



Leaves and young shoots strictly glabrous, the former terete, thick, somewhat 

 rigid, opposite, alternate or in fascicles of 3 — 5, 2 — 3 inches long. Inflorescence 

 woolly-tomentose, buds slender, less robust than the typical form; petals thin; 

 anthers glabrous on the back in all the flowers examined. 



L. gibberulus Tate, var ? referred to by Mueller and Tate in Botany Elder 

 Exploring Expedition ('IVans. Roy. Soc. S. Aust., xvi., 1882, 360) from Yilgarn, 

 Western Australia, about 36 miles N.W. from Southern Cross, parasitic on 

 Hakea sp. R. Helms. 



Mr. W. V. Fitzgerald also found it at Arrino, 175 miles N.W. of Southern 

 Cross, parasitic on Hakea decurva, Sept. 1903. The specimen is in early bud, 

 but the segments are separable into four only, and the anthers are glalirous at 

 the back. 



It is only known from Western Australia. 



Named in honoui- of the late Professor R. Tate. 



Hosts.— Froteac-eae: Hakea lorea R.Br., H. decurva Meissn.
