1. Pternandra C(erulescens, Jack in Mai. Misc. II, 61. A tree; 

 young branches cylindric with deciduous, dark-browD, glabrous bark and 

 slightly thickened nodes with obscure transverse ridges. Leaves 

 chartaceous or sub-coriaceous, broadly ovate, ovate-lanceolate, ovate- 

 oblong or elliptic, much narrowed at the base, the apex shortly 

 acuminate, 3-5-nerved ; both surfaces glabrous; length 2*5-5 in. (10 

 iu. in var. 2) ; breadth l , 25-2 , 5 in., (to 5 in. in var. 2) petiole 'l-*2 in. 

 Flowers in short, axillary, pedunculate cymes (often several from one 

 axil), or in terminal cymes, shorter than the leaves. Calyx-tube 

 cylindric-campanulate, '15 in. long, tesselate; the mouth truncate but 

 with 4 small, erect, triangular teeth. Petals thick, ovate, reflexed after 

 expansion. Stamens 8, equal in length ; the filaments short, geniculate ; 

 perfect anthers 4 or 5, broadly ovate, blunt, shortly spurred behind, the 

 remaining 3 or 4 imperfect, as long as but much narrower than the 

 perfect. Fruit turbinate or sub-hemispheric, truncate, nearly smooth,

In all the provinces except the Andaman Islands. 



A common and variable plant of which four forms seem worthy of separation as 

 varieties. These, however, pass into each other by numerous connecting specimens. 

 One variety (Jackiana) differs from the typical-plant in having few-flowered almost 

 sessile cymes ; a second (capitellata) has sub-sessile cymes and much larger leaves 

 and the third (paniculata) is probably only an example of fasciation. 



Var. 1. Jackiana, Clarke in Fl. Br. Ind. II, 551. Flowers in very 

 short, few-flowered, almost sessile, axillary cymes. Leaves as in the 

 typical form but with slightly longer petioles. 



In all the provinces except the Andaman and Nicobar Islands, 

 equally abundant with the typical form.
