;hese female flowers. His type specimen was obviously a 

 nale one with occasional female (Query: hermaphrodite) 

 'lowers, such as are common in C. papaya and occur in this 

 ipecies too. What Hooker did not know, however, was that 

 nost of the fruit-carrying individuals that are found in 

 ihe Ecuadorian mountains are purely female. There are, he- 

 lides, plenty of (preponderatingly) male individuals which 

 produce fruit but seldom. C. candamarcensis is normally 

 1 ice c ious. 



Hooker's type specimen was derived from seeds sent 

 rom Quito to England by Jameson. Hence we know with 

 jertainty that it was of Ecuadorian origin. In Ecuador C. 

 ',andamarcensis is very common in the gardens and near the

 Pastaza it is called »chamburo» but in the neighbourhood 

 )f Quito »chiluacan». It is probably this species that Spruce 

 'ound growing wild on the south-western side of the volcano 

 Cunguragua (Sfruce 1869). 



There is another Carica, called cundinamarcensis , seeds 

 )f which were originally introduced into Europe from Co- 

 ombia by Linden (catalogue 1869, 1871). It has been re- 

 garded as identical with C. candamarcensis, e. g. by Solms, 

 Bvho even cites C. cundinamarcensis Hooker, which is some- 

 ivhat incorrect. Solms refers the species to the section Vas- 

 :oncellea (fruit 5-celled, stigmata entire). The Ecuadorian 

 7. candamarcensis, however, must be referred to the section 

 Hemipapaya, as it has 5-celled fruits and bifid stigmata.

 ivhether we here really have distinct species or rares. The
