NEW INDIAN SCROPHULARTACE^ AND SOME NOTES 

 ON THE SAME ORDER. 



BY 



E, Blaiter, S.J., AND Prof. F. Hallberg. 



BON NAY A, Link. & Otto. 



Bonnaya bracteoides, sp. nov. (near B. brachiata, Link. & Otto). 



Stem erect, up to 8 cm. high, subsimple or dift'uscly branched. Branches 

 stout, rigid, quadrangular, grooved, glabrate or with a few minute haira. 

 Leaves opposite, sessile, ovate-elliptic, up to i^mm. long and 11mm. 

 broad, in some specimens only |-^ as large, very sharply spinous-serrate ; 

 teeth about a dozen pairs, up to I'Smm. apart. Flowers in terminal or 

 axillary racemes. Pedicels terete, stout, 1-bracteate, in fruit reaching 

 5mm., opposite, but with a tendency to collect into whorls or clusters, 

 especially at the top of the raceme. Bracts : the lowest pair leaf-like, the 

 next smaller, narrower, elliptic or linear, toothed, then linear-spathulate 

 with about one pair of teeth near the apex, at last very small, entire, 

 subulate, generally of the len<,;th of the pedicel. Calyx in flower 4, in 

 fruit 5mm. long, subequally 5-lobed nearly to the base, lobes linear-lance- 

 olate, acute, margins with minute stiff hairs directed upwards. Corolla 

 7mm. long, white, spotted with pink, tube 4nim. long, narrow, cylindrical, 

 outside with minute capitate hairs, lower lip 3mm. deeply 3-loDert, midlobe 

 larger ; upper lip a little over 2mm. long, rectangular, half as broad as long, 

 emarginate. Stamens 2 perfect, inserted near junction of lips ; filaments 

 very short, rather stout, glabrous : poUen globose. Staminodes 2, inserted 

 on the throat of the lower lip, reaching higher than the stamens (up to the 

 sinus of lower lip), their lower half broad, connate with the coroUa, the 

 upper narrow, bent outwards. (They are very similar to those of B. 

 brachiata, L. & O., but only obscurely glandular, not pubescent). Style 

 4mm. long, glabrous, stigma bilamellate. bent over to oi.e side, lobes about 

 equal. Capsule 10mm. long, terete, glabrous. Seeds subglobose or pear- 

 shaped, with a minute tail, obscurely rugose. 



• This species is distinguished from B. brachiata chiefly by its bracts, the 

 diflerent arrangement of its flowers and the glabrous staminodes. 



Locality: Found in October 1916 in various places of Mt. Abu, 4,000 ft. 

 (Herb. St. Xavier's College, Nos. 1514, 1515, 1516.). Common among grass 

 on wet ground. 



Bonnaya estaminodiosa, sp. nov. (near B. oppositifolia, Spreng.). 



Stem erect, ficni. high, stout, quadrangular, nearly glabrous, sparingly 

 branched. Leaves opposite, except the uppermost which are opposite to 

 a pedicel, sessile, erect, linear, 30 x 5mm., distantly, shaUowly serrate 

 (teeth about 3mm. apart), penninerved, midrib very ]iromineut, the others 

 obscure, margin v\ith tubercles and some minute stifl' hairs. — Flowers in 

 lax terminal and lateral racemes, consisting of about 5 distant pairs of 

 pedicels and, in addition, some solitary leaf-opposed ones below. Bracts 

 of about the same length as the pedicels, rather broad at the base, keeled 

 acuminate, (hairiness like that of the sepals). Pedicels up to 7mm. in fruit 

 spreading, stout, flat above, convex below. Calyx in flower 4, in fruit 6mm. 

 long, divided nearly to the base ; lobes 5, snbcqual, subulate ; margins 

 and midrib scabrous with minute distant stiff bristles. CoroUa 5"5mm. 

 long, white, lower lip spotted with pink ; tube straight, 3mm. long, narrow, 

 not widening, with a few minute capitate hairs. Lips about equal in
