NATURAL ORDERS. 131 



111 Professor Thunberg's Flora of the Cape of Good 

 Hope, where Rubiaceas arc to Pliajiiogamous. plants as 

 about one to one hundred and fifty, the order is diffcrcntly 

 constitiited ; the equuioctial division, by the addition of 

 Anthosperminn, a genus peculiar to southern Africa, some- 

 what exceeding StcUatoe in number. And in New Holland, 

 in the same ])arallcl of latitude, the relative nund)cr of 

 Stellatae is still smaller, from the existence of Oj)crcidarla, 

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

 addition of which the proportion of the whole order to the 

 Pha^nogamous plants is there considerably increased. 



More than half the Rubiacea3 from Cono;o belonu' to 

 well known genera, chiefly to Gardenia, Psychotria, 

 Morinda, Hedyotis, and Sperinacoce. 



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 iliird has the inflorescence and flowers of Xaudca, [«a 

 but its ovaria and pericarpia are confluent, the whole head 

 forming a compound spherical fleshy fruit, which is, I 

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

 Professor Afzelius.~ 



The foitriU is a second species of Neuroraqjcca, a genus 

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

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



Tho Jiff k genus is intermediate between Rubiaccic and 

 Apocinea3. With the former it agrees in habit, especially 

 in its interpetiolary stipules; and in the insertion {ind 

 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 Apocinea3 in having its

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