Clerodendron magnoli^folium, n. sp. — A shrub or small tree, 

 10-15 ft. high, glabrous in all its parts, with drab lenticellate 

 branchlets. Leaves petioled, oblong, acute, entire, deltoid at the 

 base, 2-3 in. long, subcoriaceous, glossy, green on both surfaces, 

 penninerved, with 6-8-jugate erecto -patent main veins. Flowers 

 in lax terminal cymes, on curved ^-1^ in. pedicels ; bracts minute, 

 linear, persistent. Calyx above an inch long, black, subcoriaceous, 

 with an oblong tube ^ in. diam. and five small equal deltoid- 

 cuspidate teeth. Corolla white, with a cylindrical tube as long as 

 the calyx and five subequal obovate segments half as long as the 

 tube. Stamens 4, with filaments but little longer than the corolla- 

 limb. Ovary 4-celled ; cells 1-ovuled. Fruit not seen. — Woods 

 of West Betsileo, flowering in December and January, Baron 93 ! 

 Allied to C. macrocal.ycinum, Baker, and a third endemic species 

 with a large calyx (C arenarium, Baker), gathered by Bojer in the 

 province of Imerina, and by Dr. Meller between Tamatave and 

 Antananarivo. This latter is a shrub 6-10 ft. high, glabrous in all 

 its parts, with brown lenticellate branchlets, opposite petioled 

 oblong-lanceolate leaves 2-3 in. long, numerous flowers in a lax 

 terminal cyme, a funnel-shaped membranous calyx f in. long ^ in. 

 diam. at the throat, with five large equal deltoid teeth, a fi'agrant 

 white corolla with a tube ^ in. longer than the calyx, and five sub- 

 equal orbicular segments ^-^ in. diam., and stamens and style not 

 exserted beyond the corolla-limb. 



Plectranthus Melleri, n. sp. — A perennial herb, with the young 

 branchlets pilose. Leaves petioled, oblong, acute, membranous, 

 2-3 in. long, glabrous on both surfaces, crenate above the very 

 gradually narrowed ])ase. Flowers in lax peduncled lateral 

 racemes, 2-3 in. long, 5-6 in a whorl from the central nodes ; 

 pedicels ^-^ in. long; bracts very minute. Flower-calyx cam- 

 panulate, finely pilose, |-^ in. long, with a large ovate upper lip 

 decurrent down the tube, and three deltoid-cuspidate lower 

 segments. Corolla yellow, pilose, ^ in. long, with a funnel-shaped 

 tube deflexed and dilated below the middle, a cucuUate sub- 

 orbicular lower lip as long as the tube containing the anthers, and 

 a much shorter ascending oblong upper lip. In damp places 

 between Tamatave and Antananarivo, alt. 3,000 ft., Dr. Meller ! 

 This falls in Bentham's section Coleoides, near P. coloratus and 

 Eckloni. Mr. Baron has gathered a closely-allied species (Xo. 127)
