prehend the distinction more clearly. Dr. Hamilton, at one time, 

 gave it the barbarous name of C. Mudari, but afterwards suspected it 

 to be the same as C. procera, of Persia. Dr. Wight, in the paper 

 already referred to, follows Hamilton in calling it C. procera, probably 

 through inadvertency, as in his MSS. of the East India Asclepiadese, 

 left by him in Scotland, and published in the ' Contributions to the 

 Botany of India,' it is called C. Hamiltonii, and is accompanied with 

 the remark that the Persian C. procera, judging from Andrew's figure, 

 appeared very distinct ; a supposition which has been since verified. 

 While on this subject I may allude to the little confidence one must 

 place in a mere catalogue of names, such as Steudel's 'Nomenclator 

 Botanicus.' In that work, published in 1840, only three species of 

 Calitropis are mentioned, and all are said to be natives of India, while 

 six years previously Dr. Wight described from India five species, the 

 Persian one forming a sixth. The C. acia of Hamilton and Steudel 

 is the C. herbacea of Wight, or Asclepias herbacea of Roxburgh's 

 * Flora of India.'

On the country of Cliococca tenuifolia. By G. A. Walker Arnott, 



L.L.D., F.L.S., &c. 



Although the * Phytologist ' is principally devoted to British 

 Botany, still you wWX perhaps allow me to allude to the Cliococca 

 tenuifolia of Mr. Babington, published in vol. xix. of the Linnean 

 Society's Transactions (p. 33, t. iii.). Mr. B., on the authority of 

 the Cambridge gardens, states it to be a native of New Holland, but 

 any one acquainted with South American Botany will at once recog- 

 nize its affinity with Linum selaginoides {Lam.). Of this Chamisso 

 and Schlechtendal in the ' Linnaea,' i. p. 67, describe the ten hard 

 nuts of the fruit. But the most complete account of it is by St. 

 Hilaire, in his 'Flora Brasiliensis Merid.' i. p. 130 and 131, published 

 in 1825. St. Hilaire there points out the mistake into which De Can- 

 dolle had fallen as to the colour of the petals, which are not yellow, 

 but " albida vel rufescentia, apice quandoque rosea ;" and in the de- 

 scription of the fruit, demonstrates that this very species and some 

 analogous ones, reveal the true structure of that organ in the order
