NOTES ON CRASSULA. 483 



specimens in spirit from Horfc. Kew., and others in the herbarium 

 collected at the Cape in 1771 by Banks and Solander. 



C. EXPANSA [Dryander in] Alton, I. c. i. 390, No. 4! Specimens 

 in spirit. Stem herbaceous, angled, interuodes about i-f in. long, 

 much branched, diffuse, glabrous. Leaves subconnate, spreading 

 or recurved, narrow-oblong or oblong-lanceolate, subterete, fleshy, 

 convex below, slightly channelled above, i-| in. long. Flowers 

 axillary, solitary or in twos or threes, terminal subcymose; pedicels 

 occasionally reaching 1 in. long, but mostly much shorter. Sepals 

 nearly as long as the spreading corolla, linear, blunt, with obtuse 

 interspaces. Petals elliptic-oblong, subacute. Styles shortly 

 subulate, 



C. iMBRicATA [Solander in] Aiton, I.e. 393! (1789). The type 

 specimens in the herbarium (from Masson) and in spirit leave no 

 doubt as to the identity of this plant with 0. lycopodioides Lam. 

 Diet. ii. 173 (178G), to which Harvey and others refer it. 



C. LiNEOLATA [Dryaudcr in] Aiton, I. c. 391, No. 8 ! DC. Prod, 

 iii. 390, who omits, apparently by accident, to refer to Hort. Kew., 

 from which his description is taken. Specimens in the herbarium 

 (Thunberg) and in spirit (Hort. Kew., from Masson). Stem her- 

 baceous. Leaves ovate-cordate, apex apiculate, sessile, shorter 

 than the internodes when dry ; lamina is pellucid, and has linear 

 purple lines ; bases of opposite leaves sometimes overlapping, but 

 not joined, as in C. inanjinaUs Aiton. Peduncles subterminal, 

 slender. Sepals lanceolate. Petals pointed, longer than the sepals. 



Comes between C. centnuroides Linn. PL Afr. Ear. p. 9 (1760) 

 and C. brachi/petala E. Meyer. Judging from his specimens, this 

 seems to be the plant Harvey had in view when he described his 

 (J. centanroides L. f3 vianjinalh. It differs from C. mar<jin(dis Aiton 

 in several important particulars, as will be seen from the following 

 description. C. lineolata differs from C. bracJujpctala in tbe broader 

 and sessile leaves, and in the sepals, which are shorter than the 

 petals. This species is entirely omitted by Harvey. 



C. MARGiNALis [Dryander in] Aiton, I. c. 396, No. 25 ! Spirit 

 specimens from Hort. Kew. Stem copiously branching, terete, 

 glabrous, thickening at the nodes ; internodes generally about 

 |-f in. long. Leaves sessile, connate, patent, orbicular-cordate, 

 acute or cuspidate, thick and fleshy, very slightly convex above, 

 more so below, with a narrow chestnut-coloured border on the 

 upper surface, within which is a series of dark-coloured points, 

 lamina often about -|in. long; leaves near the inflorescence smallei*. 

 Flowers in capitate peduncled cymes, which are subtended by two 

 small fleshy connate bracts ; pedicels ^-^ in. long. Sepals linear 

 acute, half as long as the petals. Petals ovate, subacuminate, 

 nearly | in. long. Stamens hardly exceeding the styles. Carpels 

 5, ovoid; styles subulate, diverging. 



This plant is well figured by Jacquin (Hort. Schoenbr. t. 471); 

 it has been considered by Harvey as a variety (/3 manjiiKilis) of C. 

 centanroides, but it seems to us distinct. Harvey under his var. 

 (i marginalis quotes Herb. Drege G889, but in this plant the leaves
