Radlkofer places this species under Euphoria and as such 

 gives it the name Euphoria long ana from Lamarack, Encyclopedia 

 Mcthodique 3:574 published in 1791. As outlined under the lychee 

 group there are ten other species in this genus of which Euphoria 

 cinerea (fur. 3), a Philippine form, is especially worthy of closer 

 study. This species is an edible form closely allied to the lungan 

 and known in the Philippines as the "alupag. " 



This fact that there are in addition to the Chinese lungan 

 other edible species with which to hybridize it, makes the field for 

 the creation of new forms of this hardier species a very promising 

 one. The possibilities of using these forms as stock on which to 

 graft the lychee, as well as the possibilities of hybridizing, make 

 imperative a systematic study and careful collection of all these 

 interesting species. 



DESCRIPTION 



The tree of the lungan, at its best, is a somewhat more hand- 

 some ornamental with higher head and spreading branches. The 

 bark of the tree is decidedly corky instead of smooth as in the case of 

 the lychee. The branches seem more brittle but the wood is not so 

 hard or highly prized by the Chinese as in the case of the lychee. 



The foliage is usually of a darker green than is that of most 

 varieties of the lychee. In early winter it flushes forth a beautiful 

 garnet brown young growth (Ridgeway, Plate i, 3 O. R. Garnet 

 Brown) which at once is a distinguishing characteristic from the 

 orange flush of the lychee (Ridgeway, Plate IT, 9 OROO Mars 

 Orange). The leaves are compound, alternate, petioled and pinnate.
