MUSACEAE 
Classification and genera : the M. are closely related to the other 
Scitamineae to which they are joined by Benth. -Hooker, and less 
closely to the Liliiflorae on one hand and the Orchids on the other. 
1 . Museae (odd sepal anterior ; ovules oo in each loc. ) : Ravenala, 
Strelitzia, Musa. Old World (exc. i sp. of Ravenala). 
2. Heliconieae (odd sepal posterior; ovules i per loc.): Heliconia. 
Confined to America. 
Muscari Tourn. ex Mill. Liliaceae (V). 40 sp. Medit., Eur., As. M. 
racemosum Mill, (grape-hyacinth) in Brit. The upper firs, of the 
raceme are neuter, serving only to give extra conspicuousness to the 
infl. (cf. Centaurea Cyanus) ; the lower are homogamous and bee- 
visited. 
Mussaenda Burm. ex Linn. Rubiaceae (1. 7). 30 sp. trop. (exc. Am.). 
One sepal is large, leafy, and brightly coloured, and helps to make the 
fir. conspicuous (cf. Euphorbia, Salvia). 
Musschia Dum. Campanulaceae (1. 1). 2 sp. Madeira (p. 148). The 
capsule opens by many transverse slits betwen the ribs. 
Mutisia Linn. f. Compositae (xii). 50 sp. S. Am. Many are climbers 
(a rare habit in C.) with the ends of the leaf-midribs prolonged into 
tendrils. All are shrubs with large heads of firs. 
Myanthus Lindl. = Catasetum Rich. 
Myoporaceae. Dicotyledons (Sympet. Tubiflorae). 5 gen. with 86 sp. 
chiefly Austr. and neighbouring Is. (1 sp. in each of the following 
areas: — Sandw. Is., E. As., Mauritius, Afr., W. Ind.). Most are trees 
or shrubs, with alt. or opp. entire exstip. leaves, which are often 
covered with woolly or glandular hairs, and frequently very reduced 
in size. Firs, solitary, or in cymose groups, axillary, $ , regular or 
zygomorphic. K (5), C (5), A 4, didynamous; anther loculi confluent. 
G (2), 2 -loc. or by segmentation 3 — io-loc., in the former case with 
1 — 8, in the latter with 1, ovule in each loc. Ovule pendulous, 
anatropous. Drupe. Endosperm. Chief genera: Pholidia, Myoporum. 
Placed in Lamiales by Benth.- Hooker, in Labiatiflorae by Eichler (see 
Bliithendiag.). 
Myoporineae (Benth. -Hooker) = Myoporaceae. 
Myoporum Banks et Soland. Myoporaceae. 25 sp. Austr., E. As., 
Sandw. Is. , Mauritius. M. laetwn Forst. f. (N. Z.) yields useful timber. 
Myosotidium Hook. Boraginaceae (iv. 1). 1 sp. Chatham Is. (p. 148). 
Myosotis Linn. Boraginaceae (iv. 4). 30 sp. Old World temp. 8 in 
Brit, (scorpion-grass, forget-me-not). The corolla-mouth is nearly 
closed by scales, and in some sp. there is a coloured ring at the en- 
trance forming a honey guide (see Life of Sprengel, in Nat. Science 
Apr. 1893). The colour of the corolla changes as it grows older (see 
order). 
Myosurus Linn. Ranunculaceae (3). 5 sp. temp. M. minimus L. 
(mouse-tail) in Brit. The receptacle is much elongated, 
Myrcia DC. Myrtaceae (1). 190 sp. trop. Am.
