8 /i2 16, no. 89; Vi 17, no. 259; fr. 17 /4 17, no. 623. — A form with larger and 

 thinner leaves was collected at the edge of the Dicksimia-ioxest on C. Salsi- 

 puedes (buds 8 /i2 16, no. yj), another with exceptionally narrow leaves among 

 rocks near this place (fi. s /i2 16, no. 86). 



Masafuera: Scattered in the higher parts, locally abundant. Ridges and 

 plains above the Chozas village, 600—1350 m (fl. 15 /-_< 17, no. 490); slopes of 

 Los Inocentes, 480—1400 m, not uncommon. 



Area of distribution: Endemic. 



Convolvulaceae. 

 Dichondra Foist. 



*92. D. repens Forst. 



Masatierra: Pto Frances, by the stream, c. 40 m. 



Masafuera: Outer part of O. de las Casas, among grass (fr. 27 /o 17, 

 no. 551). 



Xew for Juan Fernandez. A rather typical D. repens; the young leaves 

 are sericeous, the older sparingly pubescent below and glabrous above, the 

 peduncles 2 cm long or even longer. Compare Hallier in ENGLER's Jahrb. 

 XVIII (1892) 83. REICHE, FI. de Chile V. 173 includes all forms under D. re- 

 pens Forst. 



I suspect this to have been collected by BERTERO, for MoNTAGNE, Prodr. 

 Fl. Fern. 356 enumerates »Uredo Hydrocotyles Bert. Hab. ad folia Hydrocotyles?» 

 No Hydrocotyle has ever been reported from the islands; sterile Dichondra may 

 perhaps be mistaken for a species of that genus. 



Area of distribution: Subcosmopolitan (Eastern Asia, India, Africa, 

 Mascarene Islands, Australia, Xew Zealand, North and Central America, South 

 America to Patagonia and Chile, Juan Fernandez). 



Calystegia R. Br. 



93. C. tuguriorum R. Br. — Syn. C. Hantelmanni Phil., Johow, Estud. 85. 



Masafuera: Q. de las Casas (no. 412, also observed by Johow); Q. de 

 las Vacas, abundant in the outer part; Q. del Varadero. Forming dense carpets 

 on the canyon walls. 



Both J. D. Hooker and HEMSLEY united C. Hantelmanni with C. tugurio- 

 rum, but Johow kept them separate, declaring that the latter is a small herb, 

 not attaining the size of C. septum. However, CHEESEMAN, Man. X. Z. Flora 

 476 states that the stem is slender, prostrate or climbing, often clothing trees 

 and shrubs to a considerable height. During his monographical studies HAL- 

 LIER came to the conclusion that the two species are identical [ENGLER's Jahrb. 

 XVI (1893) 548;, and I have found it better to follow him. 



Area of distribution: Xew Zealand; Chatham Islands; South Chile (Val- 

 divia); Masafuera.
