11. DYSCHORISTE, Nees. 



(Calophanes, D. Don.) 

 Perennial herbs or tinderslirubs. Leaves opposite. Flowers in 

 axillary clusters or contracted cymes, bracteoles small. Calyx lobes 

 5 snbequal, narrow. Corolla obscurely 2-lipped, lobes spreading, 

 twisted to left in bud. Stamens didynamous, anthers similar, cells 

 parallel, minutely mucronate or spurred, pollen globose, ribbed. 

 Ovary glabrous, ovules 2 in each cell. Stigma linear, recurved, 

 upper lobe rudimentary. Capsule oblong, base contracted, solid. 

 Seeds 4 orbicular, miich compressed, with hygroscopic hairs, retinacula 

 strong. 



Calyx -S-'G". Corolla •75-"8", blue 1. vagans. 



Caljrx •25-"3". Corolla only slightly longer, purple 2. depressa. 



1. D. vagans, 0. Kuntze. Syn. Calophanes vagans, Wight. 



A branched siib-diffuse undershrub 1-3 ft. with minutely strigose 

 obtusely 4-anglar stems, lanceolate or ovate acute or sub-acuminate 

 leaves 1-5-3" long narrowed into a short petiole, and pretty blue- 

 lipped flowers in axillary and subterminal clusters. 



In the Central Provinces frequent up to our borders (!), which I believe it crosses 

 in Sambalpur, though I can find no Sambalpur specimens. Fl., Fr. Nov.-Dec. 



Leaves pale beneath and glabrous or puljerulous, minutely hispidulous above, 

 sec. n. 6-8 fine but distinct, running close up to margin. Clusters or cj^mes 

 glandular-pubescent, often few-fld., bract and bracteoles linear, not half as long as 

 calyx. Calyx -5" sub-2-lipped with subequal filiform-tipped teeth and stalked 

 glands. Corolla -T-'S" or tube not much exceeding the calyx, ventricose above 

 with the ventricose part keeled beneath and transversely rugose, lobes subequal, 

 oblong, truncate or slightly refuse, palate ])urple-bullate between the ribs, yellow 

 in the tube or throat. Filaments and anthers shortly hairy, anther-lobes all 

 spurred. Stjie simple, gland-hairy. Ovary oblong. 



2. D. depressa, Nees. Syn. Calophanes Nagchana, Nees. 



Stems somewhat woody at the base, numerous, often prostrate, 

 4-angular above, minutely pubescent. Leaves 5-l'5" obovate or 

 elliptic, densely minutely lineolate above, attenuate at base into a 

 0--2''' long petiole, sec. n. 3-4. Flowers much smaller than in 

 D. vagans •3--4" long, clustered axillary or on very short axillary 

 peduncles Avith a pair of small leaves, pedicels hardly any. Calyx 

 •3--35" minutely strigillose or lineolate, sepals connate about half- 

 way then produced into long setaceous tips of which midrib is 

 decurrent on the tube. Corolla somewhat shorter than or only very 

 slightly exceeding the calyx, pvirplish, tube about -15", lobes oblong 

 rounded. Stamens didynamous, one short and one long filament 

 from each pair united at the base into a flattened pubescent plate, 

 anther-cells spurred. Capsule "34" long. 

 Rare in our area. Behar, J.B.H. ! Patna, Ham. {Wall. No. 2396) ! Fl. March. 



12. PETALIDIUM, Nees. 



Shrubs or imdershrubs with entire or somewhat toothed leaves 



and large or mod. -sized (white, in our species) shortly pedicelled 



flowers axillary or in contracted spikes (or cymes .s^),* often crowded on 



* The inflorescence is described usually as cymose, but it is, I think, always 



racemose.
