34 DR. MAXWELL T. MASTERS ON THE 
believe P. ovata to belong to the section Astrophea, even if, as 
is probably the case, I have been in error in assigning some of 
the specimens mentioned by MM. Triana and Planchon to this 
species on insufficient evidence.

d Planch. l. c. p. 158. 
“Inter Tulua et Buga, n.2447, et inter Yotoco et Vijes (Cauca), 
Nov. Granat., 2247; alt. 1025, Mart. 1876. Vulgo 'dejarre-

The leaves of the living plant are described by M. André as 
dark green, the sepals greenish externally, paler within, the 
outermost coronal threads blackish violet at the base, white at 
the tips, the succeeding threads blackish violet capitate, rose- 
coloured at the ends, the innermost corona glandular, blackish 
violet, the stamens, ovary, and stigmas green. |

* Prope Vijes (Cauca), Nov. Granata, alt. 1050 met.; in rupi- 
bus arenosis aridis. Hd. André n. 2704." 
M. André's specimens have no flowers, and represent a form of 
ihis eminently variable species with ovate 3-lobed leaves, some- 
what coriaceous and more or less downy on both surfaces.

& Planchon, l. c. p. 170, pro parte. 
(1) * Portachuelo (Cauca), Nov. Granata, alt. 1000 met. ; in 
rupib. arenos. aridissim.; flor. albidi. Hd. André n. 1626" A 
form with hirsute pubescence, without subjacent tomentum ; some 
of the marginal hairs gland-tipped ; fruit yellowish, with a few 
scattered setze.—(2) “ Chinaota prope Fusagasuga, Nov. Granat., 
alt. 1100 met. In sepibus regionis aridæ arenose. Ed. André 
n. 1626 (bis)."—'* Rio Dagua, prope La Laguna, Nov. Granat., alt.

M. André makes the observation *adsunt glandule pedicellate 
brunne:s quarum pediculus vasis spiralibus preditus est glandu- 
larum Drosere instar." Thereareno flowers or fruit. These last 
represent a form with denser and more copious pubescence than 
the foregoing, the coarser hairs springing from a felted mass of
