77908. Kalaxchoe grandidibri Baill. 



La Table, Tullear, August 7, 1928. 

 An arborescent succulent plant, na- 

 tive to Madagascar, with a smooth 

 stem 3 to 6 feet high. At the top of 

 the stem a flower stalk, about 20 

 incbes high, bears a paniclelike 

 cluster of pendulous violet flowers. 



77909. Kalanchoe laxiflora Baker. 



Botanic Garden, Tananarive, Sep- 

 tember 28, 1928. A fleshy perennial, 

 native to Madagascar, with flowering 

 stems 2 to 8 feet long and oblong 

 crenate leaves about 3 inches long. 

 The pale-yellow flowers two-thirds 

 of an inch long are borne in large 

 panicles a foot long. 



77910. Kalaxchoe suarezexsis Per- 

 rier. 



Botanic Garden, Tananarive, Sep- 

 tember 28, 1928. An erect fleshy bi- 

 ennial, native to Madagascar, about 

 2 feet high, with lanceolate leaves, 

 up to 10 inches long, which bear 

 bulblets at their tips. The flowers, 

 with red calyxes and pink corollas, 

 are in many-flowered paniclelike 

 clusters. 



77911. Kalaxchoe syxsepala Baker. 



Botanic Garden, Tananarive, Sep- 

 tember 28, 1928. An erect succulent 

 perennial, native to central Mada- 

 gascar, with the lower leaves op- 

 posite, sessile, oblong-spatulate, and 

 about 1% inches long. The small 

 reddish flowers are in dense terminal 

 cymes. 



77912. Kalaxchoe sp. 



Between Betroka and Ihosy, Sep- 

 tember 19, 1928. A species with 

 brown leaves. 



77913 and 77914. Kalaxchoe tubi- 

 flora Hamet. 



An erect succulent perennial, 

 about 2 feet high, native to Mada- 

 gascar. The green cylindrical leaves, 

 irregularly striped and blotched with 

 reddish green, bear at the summit 

 small oval-oblong lobes. At the ap- 

 proach of the wet season these lobes 

 enlarge into pseudobulbils, by which 

 the plant may be propagated. The 

 red flowers are produced in a rather 

 dense cluster terminating the stem. 



77913. South of Betroka, on the 

 highway to Antanimora, Sep- 

 tember 18, 1928. 



77914. On the highway between 

 Betroka and Ihosy, September

Behara, September 10, 1928. 



77918. Kigelia madagascariensis Ba- 

 ker. Bignoniaceae. 



94537—30- — 3 



77884 to 77951— Continued. 



Betioky, August 23, 1928. A shruh 

 about 15 feet high, with showy red, 

 pink, or orange flowers about 7 inches 

 in diameter. This plant occurs widely 

 throughout southern Madagascar. Al- 

 though the plant itself is somewhat 

 straggly looking, because of the enor- 

 mous flowers which are borne in winter 

 while there are no leaves, it presents a 

 striking appearance. 



77919. Kalaxchoe sp. 



Ampanihy, September 6, 1928. A 

 shrubby succulent with thick fleshy 

 ovate leaves having rust-colored tomen- 

 tum above and silver below, both get- 

 ting dingy with age. Native to Mada- 

 gascar. 



77920. Kalaxchoe laxiflora Baker. 



Mont Vatomavy (Andohahano), 

 northwest of the village of Adena, Am- 

 bositra. at an altitude of about 6,000' 

 feet. Similar to 77909, but the stems., 

 petioles, and leaf margins have a de— 

 cided reddish tinge. 



77921. Marsdexia verrucosa (Bojer)^ 

 Decaisne. Asclepiadaceae. 



These seeds were obtained either at 

 Itrobeka. Ampanihy, where the cut^ 

 tings [No. 78441] were collected, or 

 near Tongobory, where specimens were 

 obtained. 



77922 to 77928. Mascarexhasia spp. 

 Apocynaceae. 



77922. Mascarexhasia arborescens 

 A. DC. 



Hazondrano. Collected between 

 Ambositra and Ihosy, July 27, 1928. 



77923. Mascarexhasia sp. 



Ihosy, July 29, 1928. Hazondrano. 

 A rubber-bearing shrub about 12 feet 

 high, which is similar to No. 77928- 

 but probably different. 



77924. Mascarexhasia sp. 



Ihosy, September 20, 1928. This 

 may be the same as No. 77923. 



77925. Mascarexhasia sp. 



Majunga. This is not the true 

 kompitso. 



77926. Mascarexhasia sp. 

 Ampanihy, September 3, 1928. 



Kompitso. This species is similar to> 

 and perhaps identical with No. 78455;. 

 cuttings from Behara. On casual exv 

 amination it seems to be much like 

 Mascarenhasia, except that the seedl 

 pods of this are only about 3 inches; 

 long. Possibly this is actually Gono- 

 erypta grevei, which is supposedly 

 the plant in this region known ags 

 kompitso. Considerable rubber is 

 shipped out of Ampanihy each year,, 

 all of it being known as kompitso, 

 but the natives said that this con- 

 tains a mixture of rubbers from vari<- 

 ous plants. 



77927. Mascarenhasia sp. 

 Betioky. August 15, 1928. Hasr- 



ondrano. 



77928. Mascarenhasia arborescens- 

 A. DC. 



Majunga, July 29, 1928. Haz- 

 ondrano. This shrub is identical 

 with that of No. 78443.
