 MADAGASCAR. 



By J. G.Baker, F.R.S. 



(Continued from p. 70.) 



Weinmannia trigyna, n. sp. — A shrub, with lenticellate brown 

 terete branchlets, obscurely pilose only towards the tip. Leaves 

 simple, shortly petioled, oblanceolate-oblong, obtuse, 3-4 in. long, 

 1-1^ in. broad, inciso-crenate, cuneate at the base, subcoriaceous, 

 green and glabrous on both surfaces. Racemes subspicate, shortly 

 peduncled, 4-5 in. long ; rachis pilose. Flow^ers on very short 

 pedicels, which are articulated at the top ; bracts minute, deltoid. 

 Calyx pilose, l-12th in. long; teeth deltoid, as long as the cam- 

 panulate tube. Petals oblanceolate, half as long again as the 

 calyx, ciliated. Stamens a little longer than the petals ; filaments 

 filiform ; anthers subglobose. Carpels 3, densely pilose ; styles 3, 

 glabrous, falcate, as long as the ovaries. — River banks in the 

 Tanala country. Baron 292 ! Anomalous in the genus by its con- 

 stantly trimerous ovary. 



Weinmannia FaLtenhergii, Engler in Reliq. Rutenb. 16. — East 

 Betsileo, near the forests. Baron 24 ! 208 ! A shrub, 6-8 feet 

 high. Leaflets sometimes 7. Capsule oblong, i in. long, densely 

 tomentose, with two falcate styles l-12th in. long. W. Biviniana, 

 Tulasne (of which the name is misprinted Riviniana in Dr. Engler's 

 monograph in Linn^a, xxxvi., p. 635j, seems to me con- 

 specific with W. tinctoria, Sm., and if so there is one endemic 

 species in Mauritius and Bourbon, eight in Madagascar all endemic, 

 and one in the Comero group. 



KitcJiimjia miniata, Baker. — Calanchoe miniata, Hils. et Bojer; 

 Tulasne in Ann. Sc. Nat. ser. 4, viii. 149. — A succulent perennial, 

 1-3 feet high, glabrous in all its joarts, with erect simple slender 

 terete stems, with the leaves crowded in decussate pairs near the 

 base, above it distant and much reduced in size. Lower leaves 

 oblong-spathulate, 1-|~2 in. long, crenate, sessile. Flowers in lax 

 ample terminal panicles 6-9 in. broad, with arcuate cymose 

 branches, often replaced by tufts of small fleshy leaves ; pedicels 

 cernuous, finally ^ in. long. Flower-calyx lax, broadly campanu- 

 late, ^ in. diam., \-^ in. long, with four deltoid cuspidate segments 

 as long as the tube. Corolla infundibuliform, bright red, J in. 

 long, constricted above the base, | in. diam. at the throat of the 

 tube ; segments 4, deltoid, ^-^ as long as the tube. Stamens 8, 

 inserted in a single row low down m the corolla-tube; filaments 

 filiform, |-f in. long; anthers small, subglobose. Carpels 4, 

 small, glabrous, ampull&eform, narrowed into fihform styles |- in. 

 long. Fruit calyx persistent, membranous, -| in. long. Fruit 

 carpels \ in. long, tipped with their persistent slender filiform 

 styles. — Central Madagascar, in stony soil and on walls and rocks, 

 Dr. Parker! Rocks in Noman's-land, between Imerina and Bet- 

 sileo, Baron 341 ! A very fine plant, nearly allied to the original
