LORD MAYO'S TREE (MAYODENDRON), A NEW GENUS FROM 



MARTABAN. 



Mayodendron, nov. gen. 



Calyx spathaceous, slit to about its middle, eircumsciss-deeiduous. Corolla tubular- 

 funnel-shaped, the tube short, the lobes of the limb very short, almost equal. Fertile stamens 

 4, almost equally long, up to their middle adnate to the corolla ; the fifth minute, rudimen- 

 tary ; anther-cells almost parallel. Disk annular. Ovary 2-celled, with 2 series of ovules at 

 each side of the placentas ; stigma 2-lobed. Capsule podlike, linear-cylindrical and slender 

 the valves thin coriaceous, smooth, longitudinally nerved, the septum narrow, contrary to the 

 valves, with a prominent broad ledge along its middle on both sides. Seeds in 2 rows along 

 the borders of the septum, small, elongate-winged, the wings very thin and pellucid. 



A leaf-shedding tree with ternately decompound leaves. Flowers conspicuous, crimson 

 orange, in short racemes at the ends of the branchlets or arising from short shoots above the 

 Bcar of the fallen leaves and appearing lateral. 



1. M. igneum (Spathodea ignea, Kurz in Journ. As. Soo. Beng. LX. 77). 



A middle-sized tree, 30-40 It. high with a clear stem of 10 to 18 feet by 4-6 ft. girth 

 the very young shoots minutely puberulous ; bark about J inch thick, grey, longitudinally 

 wrinkled ; cut pale-coloured ; wood white, soft ; leaves ample, resembling those of Acivcarpus 

 ternately decompound, the lower pinnoo bipinnate, the upper ones gradually simply-pinnate' 

 the rachis and petiole glabrous ; leaflets from obliquely oblong-lanceolate to falcate ovate- 

 lanceolate, 3-4 in. long, on very short petiolules, bluntish, acuminate, entire, chartaceous, 

 glabrous and glossy ; flowers showy, orange-crimson, on i-f in. long puberulous pedicels) 

 forming a short cluster- or corymb-like puberulous raceme at the end of the branches or 

 arising from the young shoots above the soars of the fallen leaves ; calyx spathaceous, about 6-7 

 lines long, shortly puberulous, green or purplish green ; corolla glabrous, puberulous within 

 the tube 2 in. long or somewhat longer, the lobes only l-^ inch, long, rounded ; pods 

 thin and slender, cylindrical, about 1 J ft. long, glabrous, with thin coriaceous valves; seeds, 

 including their thin elongate pellucid wings, narrow linear, about g inch. long. 



Ilab. Not unfrequeut in the evergreen tropical forests, especially along chouuf s of the 

 Martaban hills, E. of Tonghoo, up to 2000 ft. elevation, chiefly on metamorphio rocks, (first 

 found by Dr. IBrandis, occurs also in the Kakhyen hills, E. of Bhamo (Dr, J. Anderson), 

 H. March, Apr. ; Fr. Apr. May. 



Dedicated to the memory of Lord Mayo, late Governor-General of India, under whose 

 reign the first impulse was given to spreading Botanical knowledge amongst our foresters.
