358 THE JOUKNAL OF BOTANY 



not Cryphidium, and the combinations date from Brotherus' 

 work. 



C. ovaUfolium (C. M.) Broth, and C. dilatatum (H. f. & W.) 

 Broth, are in many respects very similar ; they may generally 

 be distinguished by the more broadly obtuse, often rounded leaves 

 of C. ovaUfolium, at least on some of the branches, principally the 

 sterile shoots (the outhne of the leaf, however, varies greatly in 

 both species, and obtuse and acute leaves may be found on the 

 same stem) ; and always by the nerve, which in G. ovaUfolium 

 ceases at some distance below the apex, and tapers gradually 

 away ; while in C. dilatatum it reaches to close below the point, 

 and ends abruptly, remaining of almost the same width through- 

 out its upper part. The leaves are more widely spreading also, 

 when moist, in C. ovaUfolium. 



Mitten seems to have misunderstood C. ovaUfolium, for all 

 the specimens at Kew collected by F. Miiller, and so named by 

 Mitten (Moreton Bay and Paramatta), have the abruptly ending 

 thick nerve reaching to near the point. In consequence of this 

 misunderstanding Mitten described in 1859 as a new species 

 Cryphcea crenulata Mitt., a specimen from "Victoria, Tarwin, 107, 

 F. Miiller," which I have no doubt is only C. ovaUfolium ; there 

 is nothing to separate it in the description, and, moreover, the 

 locality indicates that it is the very same plant that Hampe de- 

 scribed in Linnaea, 1859-60, as CrypJusa squarrulosa, " Hab. ad 

 rip. Tarwin (coll. Miiller)," which is certainly C. ovaUfolium. 

 The description agrees entirely with that ; the squarrulose posi- 

 tion of the leaves when moist conforms quite well with C. ovali- 

 foliu7n, and Miiller's figure of his plant (C squarrulosa, Anal, 

 drawings Austral. M. t. xi, 1864) leaves no doubt of its identity 

 with C. ovaUfolium. Moreover a specimen of Eeader's at Kew 

 (Victoria ; Eeader, 2) determined by Mitten as C. squarrulosa, no 

 doubt on the faith of Miiller's drawing, is certainly C. ovalifoUwn. 



I think also there is no doubt that C. Millleri (Hamp.) Par. 

 (Dendropogon Millleri Hampe) is identical with the New Zealand 

 C. dtlatatuyn (H. f. & W.). 0. dilatatum was described in 1855 

 in the Fl. N.Z. vol. ii, from New Zealand. Hampe described his 

 species in 1856, and compares it with a South American species, 

 " D. Gorveano proximus." Had he been acquainted with the New 

 Zealand species he could scarcely have failed to compare it with 

 that. His plant appears to me to be absolutely identical with 

 C. dilatatum. T. W. N. Beckett appears to have come to the 

 same conclusion, for I have a specimen collected by him in Otago, 

 N.Z., and labelled " Cryphcea Muelleri Hampe — G. dilatata Mitt." 



I should give the principal synonymy of the two plants as 

 follows : — 



Cryphidium ovalifolium (C. M.) Broth, in Engler, Pflanzenfam. 

 Musci ii, 743 (1905). 



Syn. Pilotrich'um ovaUfolium C. M. in Bot. Zeit. 1851, p. 564. 

 Gryphcea ovaUfolia Jaeg. Adumbr. ii, 98 (1874-5).
