7. DOLICHANDRONE, Fenzl 

 Trees with pinnate or sub-2-pinuate leaves and entire or obscurely 

 toothed leaflets. Flowers usually white and opening at night, large 

 or mod. -sized, in terminal corymbs or panicles. Calyx spathaceous, 

 split down one side. Corolla funnel-shaped with the lower basal 

 narrow- tubular portion well developed and much exceeding the calyx, 

 limb svib-regular. Stamens included, anther-cells parallel. Disc 

 expanded. Ovary oblong Avith many ovules several-seriate in each 

 cell. Capsule long linear with coriaceous flat valves ; septum 

 narrow with a transverse broader false septum separating the 

 placentse of each cell, so that the capsule on dehiscence appears 

 septifragal. Seeds almost rectangular with often a thick wing. 

 Leaflets sub-orbicular or broadly elliptic obtuse or suddenly acute, 



corolla 2" long » 1. falcata. 



Leaflets elliptic acuminate. Corolla 4-7" long 2. spathaeea. 



1. D. falcata, Seem., inc. D. Lawii, Seem; Karal, Or. 



A small or mod.-sized hoary pubescent tree with pinnate or sub-2- 

 pinnate (the secondaiy rhachis nearly obsolete so that the leaflets 

 appear clustered on a node of the primary rhachis) leaves. Leaflets 

 •S-l'S", rarely 2'5", long, broadly elliptic, obovate, or sub-orbicular, 

 sometimes retvise, more often rounded with a very short acute tip. 

 Flowers very pretty, Avhite in short few-fld. corymbose racemes 

 terminating the new shoots. Calyx 'e-'S", with stellate pubescence, 

 deciduous. Corolla with slender part of tube -8-1" long then 

 widening, limb 1-2" diani. with crisped rounded or oblong petals. 

 Pod 12-18" usually much curved, acuminate, glabrescent. 



Entering the western districts only in a few places from the Central Provinces 

 where it is common. Sambalpur Range, scarce ! Only seen in the Protected 

 forests. Angul, rare, B. K. Chattarjee. Fl. April-June. Fr. Feb. Deciduous 

 about Feb. -March. 



Bark grey exfoliating in irregular scales. Leaf rhachis 2-5" with usually 5-7 or, 

 in 2-pinnate leaves, i;p to 13 leaflets, pubescent or, beneath, often tomentose with 

 forked or stellate hairs, secondarj^ pinnfp usually only f i-om lowest node of primarj- 

 rhachis and consisting of three leaflets only, petiolules 0-"l" in lateral leaflets, 

 longer in terminal. Cor.ymbs pubescent, sometimes lateral on the old wood. 



Beddome saj^s that the wood is used for building and agricultural purposes. It is 

 too scarce in our area to be of consequence. 



Yar. Lawii. Syn. Dolichondrone Lawii, Seem. (sp.). 



This is considered by Brandis and also by Sprague {vide Kem Bulletin, 1919, 

 Bolichandrone and MarA-hamia) as merely a glabrous form of D, falcata and so also 

 it appears to me. It has only been collected in our province by £:urz in " Behar " ! 

 It is onl3^ puberulous on the new shoots and the pods are said to be less curved, but 

 Sprague finds that the variation in the indumentum is not correlated with the 

 degree of curvature of the pod. 



2. D. spathaeea, K. Schum. Syn. D. Rheedii, Seem. 



A large handsome tree with pinnate leaves abovit 12" long and 7-9 

 elliptic much acuminate leaflets 2-3" long, often unequal at the 

 base. Flowers very large 4-7" long with the narrow portion of tube 

 3-5". Capsule 18" by 1" nearly straight. Seeds rectangular with 

 corky wings. 



Sometimes plante<l in Orissa and near Calcutta, and may possibly be found wild 

 in the Mahanadi delta, where so many trees frequent in the Sunderbans have been 

 found. Fl. h.s.
