allies in South-western Australia. The distinction of the species 

 allied to L. carnpanulata, Br., from the same part of the country, is 

 likewise involved in much obscurity. 



One species from the same district again which I have ventured 

 to describe as new, under the name of L. micrantha, is very remark- 

 able from the ovules as well as the seeds being solitary in each 

 cell, which would technically exclude the plant not only from the 

 genus, but from the tribe, and place it in a new one to correspond 

 in Loganiacece with Spermacocece among Itubiacecd. But I should 

 regard it as rather a specific anomaly in Logania, similar to what 

 we observe in Hedyotis monosperma, W. & Arn., where the ovules 

 are likewise solitary. Eor the great development of the placenta 

 and the position of the seed seem to point to the abortion of 

 other ovules, which the observation of the ovary in a living 

 state at a very early period of growth might probably enable us to 

 detect. 



Dr. Hooker has described a species from New Zealand, so far 

 extending the limits of the genus beyond Australia itself. On the 

 other hand, it is probable that there is some mistake in the sup- 

 posed South African species described by Ecklon. No one appears 

 to have since seen it, although the Uitenhage flora is now pretty 

 well known; nor have Ecklon' s specimens been re-examined by 

 any competent botanist. 



10. Gompho stigma, Turcz. 11. Nuxia, Lam. — and 

 12. Chilianthus, Burch. 

 I have nothing to add to the distinctive characters of these three 

 genera as given in the tenth volume of the ' Prodromus,' nor have 

 any new species been added either to Gomphostigma or Chilian' 

 thus. Sonder has in the twenty-third volume of the ' Linnsea f 

 described three South African Nuxias as new. His N". pubescens, 

 which we have from Burke and Zeyher, is a well-marked one, of 

 which N. tomentosa appears, as suspected by Sonder, to be a mere 

 variety. The third, JSf. emarginata, is unknown to me. 



13. Bttddleia, Linn. 

 In this genus we have the addition of Dr. Hooker's beautiful 

 and splendidly illustrated B. Colvillei from the Himalaya, two Bo- 

 livian species described by Bemy, and both unknown to me, and 

 no less than thirteen supposed new species from Mexico, — three 

 published by Martens from Galeotti's dried collection, and ten by 

 Kunth and Bouche, from specimens cultivated in the Berlin garden.
