2. DiDYMOCARPUs.] 101. GESNERACE.E. 



Stamens 2 perfect and 2-3 rudimentary, anthers cohering in pairs, 

 cells ovate soon confluent. Ovary sometimes stalked, narrow, stigma 

 rarely 2-lobed, often peltate or vmilateral, placentse deeply inflexed 

 then recurved and bearing ovules on their outer faces only. Capsule 

 linear, loculicidally 2-valved or subfollicular, ultimately often 4-valved 

 bearing the placentte on the valves which are revolute and conceal 

 the seeds. Seeds ellipsoid, minutely reticvilate. 



1. D. pygraaea, Clarice. 



A curious little plant usually with a short straight or curved 

 succulent weak stem 1-2-5" high and a single broadly oblong or ovate 

 membranous sessile leaf I'S-S" long. Flowers inconspicuous, 1-4, 

 clustered, subsessile or with pedicels up to '3". Calyx-segments hairy 

 "1" elongating in fruit to '25'' linear. Capsule "^-'S" linear acuminate. 



On damp Ijanks and rocks in the hills of Chota Nagpnr, elev. 2000 ft. and over. 

 Rauchi, several times collected; Jonha, Wood\ Ormanjee, Clarkel and hj'^ me at 

 nearly the same place in the Damuda Ghats ! I have also collected it at Pachmari 

 in the Central Provinces. Fl., Fr. Aug'. -Oct. 



Nearly the whole plant more or less covered with hyaline hairs and the leaves 

 with a glisteninj? surface when fresh. Tliere is sometimes a short stem above the 

 single leaf bearing 1-2 very small leaves or sometimes there are two sub-opposite 

 or alternate principal but unequal leaves, or a small .subsidiary leaf below the 

 principal. Bulbils, sometimes borne instead of flowers, usually 3-gonous. Principal 

 leaf with shallowly cordate base, sometimes crenate towards apex, sec. n. 6-9 of 

 which several are near the base. Flowers appear to me to be cleistogamous with a 

 colourless corolla "1" long or sometimes '25", tubular. 



3. DIDISSANDRA, Clarice. 



Characters of Didymoca7-pns but fertile anthers 4. 

 1. D. lanuginosa, Clarice, var. minuta, Haines. 



A very small herb Avithout appreciable stem but several elliptic or 

 ovate or orbicular-ovate leaves •75-1 'S" appressed to the substratum 

 and a thinly hairy scape 2" high with 2-3 lohelia-like pale purple- 

 white flowers "4" long. Capsule linear "T-'O inches somewhat 4- 

 grooved, tapering to a short beak, 2-valved. 



On damp rocks (laterite) under shade at 3000 ft., Neterhat ! Fl. June-July. Fr. 

 c.s. Very rare. 



L. rounded at tip, base narrowed into a short broad petiole about "2" long, 

 beneath pale and with long mntted hairs on the 3-4 strong see. n.. above pilose with 

 tubercled-based hairs and nerves impressed ; sec. n. forked, their brandies ending 

 in the crenulate margin. Calyx-lobes linear oblong, 'OS-'Or". Cor.-tube somewhat 

 inflated com])ressed with two lines on lower face hirsute, less hairy l)et\veen the 

 lines, upper lij^ with 2 .short rounded lobes, lower much larger with 3 oblong obtu.se 

 lobes. Stamens included, 2 lower ascending distinct, two upper inclmed forward 

 with anthers conniving under the stigma. Pedicels clavate beneath the fruit. 

 Seeds minute brown, ellipsoid, smooth. Cotyledons (on germination) minute 

 orbicular. 



It differs from the type, which is a Himalayan plant, in the short simple scapes 

 and very small leaves and flowers. 



FAM. 102. BIGNONIACE^E. 



Trees or shrubs, often climbing (in exotic species), with opposite, 

 rai-ely whorled or spiral, 1-3-piunate, rarely simple leaves. Stipules
