NATURAL ORDERS. 131 



111 Professor Thunberg's Mora of the Cape of Good 

 Hope, where Rubiacese are to Phsenogamous plants as 

 about one to one hundred and fifty, the order is differently- 

 constituted ; the equinoctial division, by the addition of 

 AntJiospermum, a genus peculiar to southern Africa, some- 

 what exceeding Stellatse in number. And in New Holland, 

 in the same parallel of latitude, the relative number of 

 Stellatse is still smaller, from the existence of Opercularia, 

 a genus found only in that part of the world, and by the 

 addition of which the proportion of the whole order to the 

 Phsenogamous plants is there considerably increased. 



More than half the Rubiacese from Congo belong to 

 well known genera, chiefly to Gardenia, Psychotria, 

 Morinda, Hedyotis, and Spermacoce. 



Of the remaining part of the order, several form new 

 genera. 



The first of these is nearly related to Gardenia, which 

 itself seems to require subdivision. 



The second is intermediate between Rondeletia and 

 Danais, and probably includes Rondeletia febrifuga of 

 Afzelius.^ 



The tJiird has the inflorescence and flowers of Nauclea, im 

 but its ovaria and pericarpia are confluent, the whole head 

 forming a compound spherical fleshy fruit, which is, I 

 suppose, the country-flg of Sierra Leone, mentioned by 

 Professor Afzelius.^ 



The fourth is a second species of Neurocarpcea, a genus 

 which I have named, but not described, in the catalogue 

 of Abyssinian plants appended to Mr. Salt's Travels.' 



Tihe fifth genus is intermediate between Rubiacese and 

 Apocinese. With the former it agrees in habit, especially 

 in its interpetiolary stipules; and in the insertion and 

 structure of its seeds, which are erect, and have the 

 embryo lodged in a horny albumen forming the mass of 

 the nucleus ; while it resembles Apocineae in having its

 liis Report, p. 174; which is probably not different from the Belleuda or 

 African Bark ofWinterbottom's Account of Sierra Leone, vol. 2, p. 243.
