7. A. obovata, F. Muell. Herb. A small tree attaining about 20 ft., 

 the branches and underside of tlie leaves minutely and often sparingly silky- 

 pubeseent. Leaves obovate or broadly elliptical, obtuse, narrowed^ into a 

 short petiole, coriaceous, glabrous above, 3 to 5 in. long. Flowers lu axd- 

 lary clusters on pedicels about as long as tlie flowers, but attainuig 3 hues 

 then in fruit. Calyx-segments a little above 1 line diameter, orbiculnr, 

 ciliolate, membranous, the outer ones rather thicker and pubescent. Corolla 

 small, spreading sometimes to nearly 3 lines diameter, the lobes broad and 

 obtuse ; scales of the throat ovate-acuminate or linear, sometimes very small, 

 or one or two of them cpiite deficicut. Anthers often shortly excccchug the 

 coroUa. Ovary densely hairy, at least round the circumference, tapei-uig uito 

 a short thick glabrous style', 5-celled; ovules laterally attached Iruit ob- 

 OToid or oblong, i in. long or more, usually 1-seeded. Seed obovate com- 

 pressed ; hilum linear, lateral ; albumen not very thick ; P«ty^'^'^';f^''°7' 

 thin, and flat ; radicle very shod.— Sersalma obovata, K.Br. Irod. 5dU ; A.

 Howick's group, P. Mueller. In establishing the genus Senalma, Brown had seen the 

 seed only of 5. sericea, and was not aware that in the present species it was albuminous. 



ChrysojJiyll im myrsinodendron, F. Muell. Fragm. vi. ined., from Herbert river, -O'^f ^-;J{' 

 appears to me to be a form or state of this species; the flowers are .m^^^l^/^^l^'T' J"Vh^ "l 

 rently imperfcet, the scales in the throat of the coroUa are small and irregular, ^-ij J»°^5 . "'" 

 1 or 2 of them abortive, but in the Howers I examined I never found tte.u "liol > J- « '^"t- 

 There appears to me to be some kind of dimorphism or partial umsexuality in se^eial spe 

 cies of Achras. 



8. A. myrsinoides, A. Cunn. mm. A slender twiggy f^^-^^^.,?;„f7?,^J 

 tree, the voung branches' and leaves more or less pubescent or ^il^OY^X 

 full-grown leaves glabrous above or sometimes ou both sides. Leaves .Jioi -^ 

 petiolate, mostly ovate or broadly elliptical, but sometimes obovate, ob u.e, 

 narrowed at the base, 1 to 2 or rarely 3 in. long, the veins usually prommem. 

 Rowers not numerous, in axillary clusters or almost solitary, on recurmt pe- 

 dicels longer than the flower (usually about 3, sometimes 4 lines), tomemo^^- 

 pubescent. Calyx-segments 5, of which the 2 ""^'^^""'f?''^; than the

 tube, broad, truncate; scales of the throat linear. Ovary very villous, 



ovules laterally attaelied. Fruit not seen.
