GENERA FUMARIA AND RUPICAPNOS. 341 
conspicue multifloris eum pedicellis fructiferis ad 50 mm. longis et fructibus 
ellipticis ab hujus sectionis speciebus aliis insuper differt, 
Hæc species ad El Ghicha in regione montaná Djebel Amour Algerim 
australis (Pomel) primum inventa est atque prope Dyr-el-Kef Tunetim 
medize et forsan in aliis locis crescit. 
This remarkable plant has been described from Murbeck’s exsiccata in 
Herb. Mus. Brit., collated with the diagnosis of Pomel, with which it 
substantially agrees. The fanciful name “caput-platalew” or “ spoonbill’s 
head” is perhaps not inapt owing to the great apical dilation of the inner 
petals. 
Murbeck’s reference of his exsiccata to Fumaria numidica var. longipes, 
Cosson, is probably due to the great length of the fruiting pedicels, which 
characterizes this plant in common with X. longipes. In every other respect, 
however, R. caput-platalee is widely different from the annual species 
distinguished by Cosson.
