1. GLOBBA Linnaeus 



Usually slender erect herbs with leafy stems, from short rootstocks, 

 the leaves distichous, ovate to lanceolate, basal part sheathing the stem, 

 ligulate. Inflorescence terminal, dense arid spicate or racemose, or more 

 lax and paniculate. Flowers small, yellow or white. Calyx tubular, 3- 

 toothed, regular or irregular. Corolla-tube slender, longer than the calyx, 

 3-lobed, the lobes boat-shaped, deflexed. Staminodes similar to the lobes. 

 Base of the lip adnate by its edges to the stamen, forming a tube below, 

 its limb free, narrow, elongated, deflexed, usually 2-lobed. Filament elon- 

 gated, erect, slender. Connective of the anther extended laterally into an 

 entire margin, or sometimes with 2 or 4 triangular spurs. Ovary 1-celled. 

 Capsule globose, smooth or verrucose, fleshy, dehiscing irregnilarly. (From 

 its Ambojmese name "galoba.") 



Species about 75, tropical Asia to New Guinea, about 10 in the Philip- 

 pines. 



1. G. MAEANTINA L. 



Erect, glabrous or sparingly pilose, 25 to 60 cm high, from slender root- 

 stocks. Stems rather loosely covered with sheaths. Leaves ovate to 

 elliptic or lanceolate, acuminate, 8 to 15 cm long. Inflorescence dense, 

 spike-like, 2 to 8 cm long, the bracts persistent, ovate, green,, gland-dotted, 

 ciliate on the edges, 1 to 2 cm long, frequently containing ellipsoid to 

 conic bulbils in place of flowers. Flowers yellow, slender, about 5 cm 

 long. Calyx tubular, 3-toothed. Corolla-tube much longer than the calyx, 

 glandular-dotted. Lip short, oblong, cuneate, widely retuse. Anther- 

 spurs 4, triangular, equal. (Fl. Filip. pi. 351.) 



In thickets, Masambong to Pasig and Pasay, fl. June-Sept.; widely dis- 

 tributed about towns in the Philippines, certainly introduced. Amboyna 

 and Celebes to New Guinea, a weed of cultivation in Java, Singapore, etc. 



2. HEDYCHIUM Kocu-e, 



Terrestial erect herbs with elongated leafy stems from stout rootstocks. 

 Leaves distichous, sessile or shortly petioled, ligulate, oblong to linear- 

 oblong or lanceolate, acuminate. Inflorescence a terminal, usually dense.
