described it under the name of Slum latijugum Clarlie. This is an Indian 

 species, for whose inclusion in Simn Clarke altered one of the generic 

 characters by mailing the furrows of the fruit univittate. Since then 

 specimens have been sent from South Austraha to Calcutta and care- 

 fully examined by the Director of the Royal Botanic Garden at Sibpur 

 (Major Gage) and Mr. M. S. Ramaswami, who find that our plant difters 

 from S. latijugum in the narrow slender ridges of the carpels and in the 

 shape of the leaflets. They advise placing it in Apium and instance 

 its resemblance to A. nodiflorum Reichb. It seems to me, however, that 

 the bipartite carpophore and the emarginate petals exclude it from that 

 genus, and I have placed it in Carum, with which it agrees very fairly, 

 especially when the generic character is extended so as to include 

 Petroselinum Hoffm. Although in our plant the branches of the carpo- 

 phore usually remain united to the carpels and fall off with them, they

are sometimes seen, in the ripe fruit, free from them for a considerable 

 part of their length. It is only in specimens from Nuriootpa that I 

 have found 1 or 2 pinnatifid bracts in the involucre, and of these spe- 

 cimens I have not been able to obtain fruits. The plant here described 

 is very probably the Slum latifoUum L., mentioned in Fl. Aust., Ill, 336, 



as an introduction. There can be little doubt that it is a native.

1054. Helipterum florihundum DC. var. tubulipappum J. M. Black, 1. c, 

 p. 23. — Corollae lobis inaequalibus, uno profunde inciso, pappi setis 

 planis 6— 8, dimidio inferiore in tubulum connatis. — South Australia: 

 Oodnadatta (Miss Staer). A variety with slightly woolly, rigid branches, 

 the involucral bracts all pure white, as in the type, but pappus semi- 

 tubular, as in H. Troeddii P. v. M. Similar specimens from Mount 

 Lyndhurst, labelled „I£. floribundum", are in the herbarium of the Mu- 

 seum of Economic Botany. Differs not only in pappus, but in the larger 

 leaves and stouter stems, from the slender form found in the mallee 

 country from Dublin northwards towards Port Augusta, with the outer 

 bracts golden- brown and the appearance of an annual (? var. Sturtianum 

 Benth.). The flowers in each head of var. tubulipappum number over 

 100. (Plate II.) 



1055. Senedo odoratus Hornem. var. obtusifoljus J. M. Black, I c, 

 p. 24. — Differt a forma typica foliis obovatis glaucis crassiusculis flac- 

 cidis confertis, auriculis parvis parce dentatis, panicula densiore. 

 South Australia: Along the coast at Port Elliot. This low. leafy 

 shrub seems to be a maritime form of S. odoratus. Although it has a 

 ^ery distinct aspect, I can see no difference in the flower-heads which 

 ^vould justify raising it to the rank of a species. (Plate III.) 



1056. Leucopogon hirtdlm P. v. M. var. glabrifolius J. M. Black, 1. c, 

 P- 24. _ South Australia: Eyre Peninsula (S. A. White), exact loca- 

 % not given. Differs from the type, which is only recorded from Victor 



Repertorium specierum novamm. XIV. (30. VI. 1916). "3
