2-lipped, divided half way down, cylindrical, rounded at the tip (the lobes 

 remaining as in bud, upper lip external), 1-l^mm. long, lips equal in 

 breadth, upper lip suborbicular, hooded, tip emarginate or with a few 

 irregular teeth, lower lip equally 3-lobed, as long as the upper and with 

 Buborbicular lobes or shorter than the upper and with oblong lobes. The 

 corolla is persistent as a small cap on the beak of the growing capsule. 

 Perfect stamens 2 ; filaments very short, stout, as long as or shorter than 

 the anthers, anthers 2- celled, cells equal, situated at about the same height, 

 slightly diverging below, anticous citamens reduced to minute staminodes, 

 cjdindrical, eglandular or with a lower, swollen glannular and upper sub- 

 clavate eglandular part. Style very short, stont, conical ; stigmatic bran- 

 ches conspicuous, longer than the style, reflexed, unequal in length. — 

 Capsule elongate ovoid, 7mm. long, broadest below the middle (2-5 mm.), 

 acutely beaked by the enlarged style, bivalved, the valves separating from 

 the septum, but remaining united with each other at the apex. Seeds 

 brown, ovoid, with a minute tail at one end, faintly longitudinally ribbed, 

 obscurely rugose, sometimes slightly echinulate. 



Locality: Mt. Abu, on walls, Oct. 1916 (No. 1734), Igatpuri, Sept. 1917 

 (Nos. 1735, 1736), Lonavla (No. 1765). 



This is a very distinct species and of interest from several points of view. 

 It differs from the other species of Bonnaya with regard to the capsule and 

 the nervation of the leaves. — The corolla is eafily overlooked, the most 

 conspicuous feature of the plant being the profusion of fruits. The corolla 

 never opens and, thus, self-pollination is the only possibility. It is perhaps 

 worth mentioning that so far no corolla has been observed in the pedicelled 

 flowers. The pedicel may have developed after flowering. 



Bonnaya brachiata, Link & Otto. — This plant is very common near Bom- 

 bay during the rains. In addition to the localities given by Cooke wo 

 have obtained the plant from Bombay Island (No. 1526), Salsette (Nos, 1501, 

 1502, 1503, 1504, 1505, 1506), Khandala (No. 1507), Igatpuri (Nos. 1509, 

 1510, 1511, 1512, 1513). 



It varies considerably with regard to the size of all its parts, branching, 

 form and colour of the corolla, etc. The bracts are always uniform, subu- 

 late. The staminodes are shaped like those of B. bvacteoides, but the broad 

 lower part is pubescent, the hairs being either white or assuming the colour 

 of the corolla. In this species as well as in the three species described 

 above, we have always found a few minute cai^itate hairs on the outer side 

 of the corolla. Extreme measurements of the corolla : 11mm., white with 

 purplish blue spots (No. 1512), 5*5mm., pink (No. 1505). 



Bonnaya veroniccefoUa, Spreng. — This plant seems to be rare about Born- 

 bay. We have seen specimens only from Kakeri (No. 1519) and Kodai- 

 kanal Iload (No. 1520). 



Bonnaya y randiflora , Spreng. — This, on the other hand, is rather common. 

 It was obtained from Campooli (No. 1521), Salsette (No. 1522), Penu 

 (No. 1523), Begur in Mysore (No. 1524). 



Bonnaya verbencefolia, Spreng. — It is not common. We have got it from 

 Castle Rock (No. 1525) and from damp spots on the slope of the High Wavy 

 Mountain in Madura, alt. 3,000 ft. (Nos. 505, 506). 



As regards B. veronicc(ffolia, B. yrandijlora, and B. vevbmcpfolia, there is 

 apparently no reason why they should not be regarded as distinct species. 

 J. D. Hooker has brought the last two under the first as varieties. The 

 habits of the plants, however, are entirely difterent, and agree well with 

 the figures in Itoxb. Cor. PI. II. 154, 179. and Wicht Ic. t. "^1412. taken in
