18. LEUCOCARPUS D. Don. 

 Leucocarpus D. Don in Sweet. Brit. Flow. Gard. II. pi. 124. 1831. 

 Type species, Conobea alata Graham, of Mexico. 



1. Leucocarpus perfoliatus (H. B. K.) Benth. 



Mimulus perfoliatus II. B. K., Nov. Gen. et Sp. 2: 371. 1818. "Crescit 

 in Regno Novo-Granatensi. ... A Mutisio cum Bonplandio com- 

 municatus." Described as with leaves connate, but this appearance has 

 misled subsequent workers, including Bentham in his characterization 

 of Leucocarpus. The plant actuallv has opposite cordate-clasping leaves. 



Leucocarpus perfoliatus (H. B. K.) Benth. in DC. Prod. 10: 335. 1846. 



This species has usually been called L. alalus (Graham) D. Don, 

 based upon Conobea alata Graham (1830) of Mexico, a plant more 

 carefully described and under an appropriate name. The character 

 of length of calyx-lobes, used by Bentham, is of no significance, 

 the lobes varying in the same specimens and usually seeming rela- 

 tively longer when in the bud. 



Corolla yellow throughout, with two pubescent ridges within 

 throat anteriorly. Plant shrubby below, from a perennial root 

 sending up a clump of many long densely floriferous stems. Fruit 

 fleshy, chalky-white. 



Along stream banks in forest, at altitudes of 1350 to 2000 meters, 

 probably from all slopes of the Cordilleras, and also on the Sierra 

 Nevada de Santa Marta. Subtropical zone. Ranges from Mexico 

 to Bolivia. The seeds are doubtless carried by birds. 



Huila. Cordillera Oriental, east of Neiva (along rocky stream in 

 forest, alt. 1500-2000 m.), Rusby & Pennell 600. 



Magdalena. Las Nubes (damp clearing near stream, alt. 1350 m.), 

 H. H. Smith 1405 (C, H, U, Y). 



Tolima (?). "Forets de Quindio" (2200 m.), J. Triana (U). 



Valle. Jicaramata, "circum flumen Toluam", I. F. Holton 578.
