348 LlX. BlGNONIACEiE. [Millingtonic 



minate, petiolulate, the blade 1-2 in. long. Flowers numerous, fragrant 

 pure white, in large terminal panicles ; bracts minute, ciliate. Corolla 3- 

 in. long. Capsule 12 in. long. 



Cultivated in avenues and gardens in most parts of India, believed to be in- 

 digenous in Burma and the Indian Archipelago. In North India the culti- 

 vated tree seeds very rarely. Attains 50-60 ft., bark corky, deeply cracked. 

 Fl. C.S. Wood whitish, firm and close-grained. Weight 42 lb. ; value of P. 

 610. 



3. SPATHODEA, Beauv. 



Trees with opposite (rarely alternate) imparipinnate or bipinnate leaves. 

 Flowers in racemes or in terminal trichotomous, cymose panicles. Calyx 

 truncate lobed or spathaceous. Corolla funnel-shaped, limb oblique, the 

 lower cylindrical part of the tube varying in length, the stamens inserted 

 at its upper end, so that when it is very short, their insertion is at the 

 base of the corolla. Stamens 4, didynamous, with a 5th staminodium ; 

 anthers 2-celled, cells divergent or parallel. Ovary 2-celled, ovules in 

 more than 2 rows in each cell. Capsule cylindrical, valves woody or 

 coriaceous, opening loculicidally in 2 valves, the dissepiment free at the 

 time of dehiscence, transverse with relation to the valves, and before 

 dehiscence attached to their median line. Seeds numerous, flat, with 

 long lateral wings, attached (2 rows in each cell) along two prominent 

 lines (the lines of attachment to the valves) of the dissepiment ; embryo 

 flat, cotyledons broad-rotundate, auriculate at the base, radicle short. 



Leaves bipinnate ; stamens inserted near the base of corolla. 

 Pubescent ; calyx campanulate, 5 -dentate ; pod hard, woody, 



tuberculate, more than 1 in. diam 1. S. xylocarpa. 



Glabrous ; calyx split into 2 lips ; pod slender, coriaceous, 



\ in. diam 2. S. amcena. 



Leaves pinnate. 



Calyx spathaceous ; stamens inserted near the throat of the 

 corolla. 

 Leaflets rotundate, 1 in. long, the lateral short-petiolulate ; 



corolla-lobes oblong, flat ; capsule flat, smooth . 3. S. falcata. 



Leaflets ovate-oblong, 2 in. long, the lateral long-petiolulate ; 



corolla-lobes rounded, curled ; capsule convex, rough . 4. S. crispa. 

 Calyx bilabiate ; stamens inserted near the base of the corolla 5. S. Hoxburghii. 



The genus Spathodea, as here defined, will certainly not remain undivided, 

 and should be confined to the species with pinnate leaves, racemose flowers, 

 spathaceous calyx, and stamens inserted at the top of a long cylindrical corolla- 

 tube. Whether S. xylocarpa and S. amoena should be referred to Raderma- 

 chera, Zollinger, to which they approach by their cylindrical dissepiment, I do 

 not venture to decide with the materials before me. In that case Raderma- 

 chera would include a very heterogeneous group with pinnate (R. stricta, Zoll.) 

 and bipinnate leaves, with the calyx truncate {stricta), split into 2 lips (gigantea, 

 Miq., amcena), and 5-dentate (xylocarpa), not to mention the difference between 

 the thick woody valves of R. xylocarpa and the membranous or coriaceous 

 valves of most other species. Another question to be decided is, whether 

 Heterophragma is to remain, or, as proposed by Bureau 1. c. 50, to be merged in 

 Spathodea, from which it differs by the bilabiate calyx and the stamens inserted
